SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION

Emphasis upon publication as a means of “diffusing knowledge” was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: “It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge.” This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series:

Smithsonian Contributions to Anthropology

Smithsonian Contributions to Astrophysics

Smithsonian Contributions to Botany

Smithsonian Contributions to the Earth Sciences

Smithsonian Contributions to the Marine Sciences

Smithsonian Contributions to Paleobiology

Smithsonian Contributions to Zoology

Smithsonian Studies in Air and Space

Smithsonian Studies in History and Technology

In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world.

Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover.

ABSTRACT

Krombein, Karl V. Biosystematic Studies of Ceylonese Wasps, IX: A Monograph of the Tiphiidae (Hymenoptera: Vespoidea). Smithsonian Contributions to Zoology, number 374, 121 pages, 64 figures, 1982.—Forty-six species are recorded from Sri Lanka in the following subfamilies: Anthoboscinae with one species of Anthobosca Guérin; Tiphiinae with 30 species of Tiphia Fabricius; Myzininae with five species of Mesa Saussure and two of Hylomesa Krombein; Methochinae with three species of Methocha subgenus Methocha Latreille, four species of Methocha subgenus Dryinopsis Brues, and one species of Karlissa Krombein. Thirty-seven species are known from both sexes, and nine from only one sex. Thirty-one species occur only in Sri Lanka, and 15 are found also in India or are more widely distributed in the Oriental Region. Specific hosts are unknown, but it is presumed that all taxa are parasitic on coleopterous larvae in the soil, in rotting wood, or in cavities in twigs or sound dead timber.

The 33 new taxa are Anthobosca ceylonica, Tiphia leclercqi, T. kaszabi, T. sakagamii, T. knutsoni, T. hillyardi, T. bouceki, T. moczari, T. tsunekii, T. gurneyi, T. kurczewskii, T. bakeriana, T. weismani, T. pulawskii, T. wittmeri, T. wirthi, T. carvalhoi, T. vanlithi, T. hirashimai, T. dayi, T. fennahi, T. wahisi, T. sabroskyi, Mesa karunaratnei, M. flavipennis, Hylomesa anomala, Methocha (Methocha) litoralis, M.

Introduction

The Tiphiidae, with 46 known species, is one of the largest families of Ceylonese aculeate wasps. Thirty-seven species are known from both sexes, and nine from only one sex. In addition, it is probable that some species, especially of Tiphiinae, still await discovery because three species of Tiphia are known only from uniques and three others from two to five specimens each. Tiphiidae occur from sea level to at least 2700 meters altitude and in both the Dry Zone and Wet Zone with the average rainfall ranging from 860 to 3900 millimeters.

Thirty-one species are known only from Sri Lanka, and 15 occur also in India or are more widely distributed in the Oriental Region. I anticipate that thorough collecting in South India will probably demonstrate that some of the 31 species apparently endemic to Sri Lanka occur also in that country.

So far as known, all Tiphiidae parasitize coleopterous larvae. Members of most subfamilies parasitize larvae of Scarabaeidae in the soil or decaying wood, but Hylomesa of the Myzininae parasitizes larvae of Cerambycidae in burrows in wood, and all members of the Methochinae parasitize larvae of Cicindelidae either in the soil or in cavities in twigs. Putative hosts are reported for the Ceylonese Methochinae in the discussion of that subfamily. Hylomesa longiceps (Turner) was reared in India from a cerambycid larva in dead wood. Hosts of the other Ceylonese Anthoboscinae, Tiphiinae, and Myzininae are unknown but are presumed to be scarabaeid larvae.

Until this time relatively few species of Tiphiidae have been described from Sri Lanka. The earliest was Tiphia decrescens Walker, 1859. Twenty years passed before Smith (1879) described T. consueta. Bingham described Methoca [sic] nigra in 1896, a species he synonymized a year later as the opposite sex of T. consueta. Cameron described Methoca [sic] rugosa in 1897, a species now placed in Karlissa. Cameron described Myzine ceylonica in 1900, a species now recognized as the opposite sex of the Indian Mesa petiolata (Smith).

This present contribution also constitutes number XIII of my series “Studies in the Tiphiidae” but will not be published under that series title. The preceding number in that series is “A New Genus of Methochinae with Notes on the Subgenera of Methocha Latreille (Hymenoptera Aculeata),” Proceedings of the Entomological Society of Washington, 81:424–434, 5 figures, 1979.

ACKNOWLEDGMENTS

My field work in Sri Lanka was funded by Smithsonian Research Foundation Grant SFG-0-6955, and travel was provided in part by grants from the Secretary's Fluid Research Funds.

Within Sri Lanka I am indebted to Co-Principal Investigator W.T.T.P. Gunawardane, assistant in entomology, Department of National Museums, for planning itineraries and arranging accommodations for our field parties. I am particularly grateful to P.B. Karunaratne, former curator of insects at the Museum, who accompanied me on many of the field trips which resulted in the collection of a majority of specimens on which this study is based.

I am indebted to the following for the loan of material: P.H. Arnaud, Jr., California Academy of Sciences (San Francisco); C. Besuchet, Natural History Museum, Geneva, Switzerland (Geneva); P.

SYSTEMATICS

Six subfamilies are currently recognized in the primitive wasp family Tiphiidae (Brothers, 1975), the Anthoboscinae, Thynninae, Tiphiinae, Brachycistidinae, Myzininae, and Methochinae. Four of these subfamilies occur in Sri Lanka, but the Brachycistidinae are found only in the desert areas of the southwestern Nearctic Region, and the Thynninae range throughout the southern half of the Neotropical Region and in New Zealand, Australia, and Melanesia westward to Celebes and northward into the Philippines.

The habitus illustrations (Figures 1–8) of both sexes of the Ceylonese subfamilies of Tiphiidae should assist readily in placement of these wasps in the proper groups.

The fully winged females of the Anthoboscinae, Tiphiinae, and Myzininae except Hylomesa Krombein have well-developed modifications for fossorial existence, such as the enlarged femora and tibiae armed on the outer surface with stout thorns. The female of Hylomesa is unique in having a porrect quadrate head with the mandibles placed anteriorly (Krombein, 1968, pl. 1: figs. 6, 7), whereas the other tiphiid females from Sri Lanka have the head short and transverse with the mandibles placed ventrally. Female Methochinae are remarkable in being completely wingless and very antlike in appearance; however, they lack the characteristic node between the thorax and main part of the abdomen. Females of Anthoboscinae differ from those of the Tiphiinae and Myzininae in having extensive yellow maculations, whereas those of the latter two subfamilies are entirely black or black and red. Females of Tiphiinae have a propodeal areola and the tegulae covering the axillary sclerites of the forewing, whereas the propodeal areola is lacking in Myzininae, and the tegulae are smaller and do not completely cover the axillary sclerites.

Males of Tiphiinae, Myzininae, and Methochinae are separated from those of all other Ceylonese wasps by having the apex of the eighth abdominal sternum protruding as a stout recurved aculeus. Males of Anthoboscinae lack such an aculeus and have more extensive yellow maculations than other tiphiids. Male Tiphiinae are stouter than those of Myzininae and Methochinae and lack notauli on the scutum, whereas the notauli are weakly defined and oblique in the latter two subfamilies. Finally, males of Myzininae differ from those of Methochinae in having a nodose first abdominal segment.

TREATMENT OF INDIVIDUAL TAXA

The Ceylonese taxa are treated according to their respective subfamilies. Under each subfamily heading is a discussion of the number of genera and species included, their distribution, and biological data. There follows a key to the genera and species of each subfamily.

In the section following the key are detailed treatments of each of the species. The references cited beneath each specific heading include the original description and those of any synonyms, notes on type fixation when appropriate, and all other references citing the taxon.

Several paragraphs of discussion follow on such subjects as distribution, synonymy, type fixation where required, and differentiating characters. Next are descriptions of the female and male when both sexes are known. Finally there is a listing of the specimens examined arranged by province and district.

Label data are given in full for the type series of all new species. Label data for specimens of previously described taxa have been consolidated insofar as possible. For example, one consolidated record under “4. Tiphia oswini Turner” reads “9art, 12art, Nuwara Eliya (includes Galway Natural Reserve, One Tree Hill, Mt. Pidurutalagala), 1900 m, 6500–8200 ft, 2 Jan, 14 Feb, 4 Mar, 28 Apr, 10, 27–29 May, 10 Jun, 30–31 Jul, 28 Sep–1 Oct, 8 Oct, 21 Nov, Brinck et al., Davis et al., Hevel et al., Karunaratne et al., Keiser, Krombein et al., Messersmith et al. (USNM, Colombo, Basel, Lund).” Following the number of specimens and locality are specific dates of collection, except that the year is omitted. Dates are followed by names of collectors, except that only the name of the first collector is cited from a label bearing the names of two or more collectors. Finally the depositories in which the specimens are located are cited in parentheses. The only abbreviation used is USNM (former United States National Museum collections deposited in the National Museum of Natural History, Smithsonian Institution); other depositories in parentheses are more fully identified in paragraph 3, “Acknowledgments.”

Family TIPHIIDAE

Key to Subfamilies of Ceylonese Tiphiidae

Subfamily ANTHOBOSCINAE

The only representative of this subfamily is Anthobosca ceylonica, new species, a species distinct from all other Ceylonese tiphiids in that both sexes are profusely maculated with pale yellow. Other distinguishing characters are mentioned in the foregoing key to subfamilies.

The genus Anthobosca occurs chiefly in the Southern Hemisphere where a number of species have been described from Australia, South America, and Africa, but none from the Orient. To date, the genus has not been recorded from India, and the closest geographical relative of A. ceylonica is A. arabica Turner, described from Aden and known only from the female.

A Chilean species of Anthobosca has been recorded as a parasite of a scarabaeid larva in the soil. It is presumed that the single Ceylonese species has a similar host, for the female wasp has the legs strongly modified for fossorial use.

1. Anthobosca ceylonica, new species

FIGURES 1, 2, 9

This Dry Zone species, known only from the northwestern part of Sri Lanka, is distinguished from its closest geographical relative, the Arabian A. arabica Turner as follows: clypeal margin gently rounded instead of truncate; apex of pygidium shagreened rather than finely punctate; marginal cell narrowly truncate at apex, not rounded, and extending slightly beyond third submarginal cell; clypeus with a yellow spot; scutellum lacking a yellow band; and wings slightly infumated rather than hyaline.

Most of the type series was collected 22–25 May 1976 just north of the Modaragam Aru near Kokmotte Bungalow, Wilpattu National Park. One female and 10 males were collected with hand nets, and 16 males were caught in a Malaise trap. We revisited this locality during January and October 1977 and February 1979 and set the Malaise trap at the identical site, but we obtained no additional specimens. Two females were collected in January 1978 at two localities only 15 miles north of the type-locality.

The female paratypes are 7.5 mm and 11.0 mm long. Both females have larger yellow markings than does the holotype, and in addition each has a small lateral spot on scutum, a small spot above on mesopleuron, a spot at base of propodeum and a pair of median spots on posterior surface, and small spots at apices of outer surface of all femora. Male paratypes are 5.4–10.0 mm long. There is considerable variation in the number and size of yellow maculations, and smaller specimens are darker. The most brightly marked specimen has larger spots on the abdomen, the spots on second meeting on midline, and those on third and fourth are narrowly separated, the femoral and propodeal markings are more extensive, and the first abdominal tergum has a small oblique spot on side. The least maculated specimen has much smaller maculations on front, vertex, abdominal terga, femora and tibiae, the pronotum has only a posterior band on dorsum and tiny spot on lateral surface, and yellow spots are lacking on scutellum, postscutellum, mesopleuron and propodeum.

Subfamily TIPHIINAE

Tiphia Fabricius is the only genus of Tiphiinae that occurs in Sri Lanka. It is one of the most difficult genera in the Ceylonese wasp fauna insofar as specific discrimination is concerned. There are many species; sex associations are sometimes difficult because of the sexual dimorphism, and some species exhibit a disconcerting degree of variability in punctation and reddening of the appendages. Thirty species have been collected in Sri Lanka, 21 species occurring in Sri Lanka only, and nine occurring also in India. It is more than likely that some Dry Zone species now known only from Sri Lanka will be found in South India also when more thorough collecting is done in that area. Furthermore, six Ceylonese species are known from less than six specimens, three of them from uniques, so it is quite probable that we have not yet obtained the entire tiphiine fauna. Bingham (1896:431) recorded T. rufofemorata Smith from Sri Lanka, but this was certainly a misidentification of this Indian species; considering the locality from which he recorded it, I suspect that he had a female of what is described herein as T. dayi, new species.

The wealth of material collected during my 12 field trips in Sri Lanka has enabled me to make sex associations in 23 of the 30 species obtained. Previously, only the two sexes of T. oswini Turner had been associated. Of the seven remaining species, all of them new, three are known only from females (T. moczari, T. tsunekii, and T. weismani) and four only from males (T. bakeriana, T. kaszabi, T. sabroskyi, and T. wahisi).

Ideally, sex associations are based on the capture of mating pairs; however, only rarely are species of Tiphia taken in copula, suggesting that the female mates only once and for a relatively brief period. The only records I have are my capture in copula of a pair of T. dayi, new species, and of a pair of T. consueta Smith. P.B. Karunaratne captured newly emerged females and males of T. hirsuta Smith on the ground at the Colombo Museum but observed no mating. I have seen two newly emerged females of T. dayi and one of T. tsunekii resting quietly on foliage. I suspect that they were ready to mate and were releasing a pheromone to attract males. Newly emerged wingless females of a new mutillid genus and species to be described by Børge Petersen behave similarly, and the pair is often caught on the foliage or in flight.

The rarity of mating pairs requires that sex associations be based on other criteria. One important criterion is the capture of both sexes at several localities. These data must be considered together with characters such as coloration of the legs, antennae and wings, the shape and color of the tegulae, and comparative density of the punctation which is sometimes similar in the two sexes.

Female species with light red legs and antennae usually have males with similar coloration except that parts of the legs, especially the hind tarsi, and the dorsal surface of the antennae may be infuscated. Species having such coloration in both sexes are T. carvalhoi, new species, T. hillyardi, new species, T. kurczewskii, new species, T. pulawskii, new species, T. palmi Krombein, T. sakagamii, new species, T. tegulita Allen, T. vanlithi, new species, and T. wirthi, new species. The female of T. gurneyi, new species, has predominantly reddish legs, but not the male. The male of T. bouceki, new species, has reddish legs, but not the female. The females of T. weismani and T. tsunekii have light red legs, but the males are unknown.

Females of T. dayi, T. fennahi, new species, and T. hirashimai, new species, have dark legs except for the bright red mid and hind femora. Legs of their respective males are mostly dark, and the sexes are associated on the basis of relative density of punctation, size and occurrence at some of the same localities, and, in the case of T. dayi, on the basis of the capture of a pair in copula.

Similarly colored wings in both sexes is extremely unusual. It occurs only in T. pulawskii, which has bright yellow wings in both sexes. Normally, the female forewing is darker, ranging from infumated to infuscated, whereas in males the forewing is clear or only slightly infumated. Two species, T. hillyardi and T. hirsuta, have yellow forewings in the female but clear or lightly infumated wings respectively in the male.

The shape of the tegula is the same in both sexes, and the color is usually similar, so these are useful corroborating characters for sex associations. Most species have tegulae with a more or less circular outline (Figure 41) and with the length only slightly greater than the width, but nine species have elongate tegulae (Figure 42) with the length at least 1.5 times greater than the width. Frequently the tegula is opaque black in both sexes, but there are some species with the posterior part and outer edge transparent and light brown or testaceous, and so part of the axillary sclerites of the forewing may be seen, and other species have the entire tegula transparent and testaceous or light red, so all of the axillary sclerites may be seen.

Emergence from the soil may occur during periods of inclement weather. At Nuwara Eliya during a continual overcast and very light drizzle, newly emerged males and females were alighting on foliage, but no mating was observed. During a period of two hours, we collected a female of T. pulawskii, new species, five pairs of T. oswini, three females of T. moczari, and eight females and 25 males of T. dayi. On the Adams Peak Trail under constant overcast and intermittent heavier showers, we collected the type series of T. leclercqi, new species (1art, 5art), and the unique female of T. tsunekii.

Hosts of the Ceylonese Tiphia are unknown. It is presumed that they will consist of subterranean scarabaeid larvae, as has been ascertained for a number of species from India, China, Korea, and Japan. Females of the Ceylonese species have a pecten of spines along the posterior margin of the foretarsus and an armature of short coarse thorns covering the outer surfaces of the mid and hind tibiae (Figure 4a,b). These are normal for the genus and indicate that the females lead a fossorial existence searching for host larvae. Some Ceylonese species have the tarsal pecten composed of shorter, weaker spines than is normal, and the mid and hind tibiae may bear fewer and weaker thorns. These developments suggest that the host larvae may occur in a more friable substrate such as sand or decaying wood.

The limited distribution and scarcity of some species suggests that they may be host specific or confined to hosts in very specialized ecological niches. Taxonomic difficulties due to variability in wide-ranging, common species may be associated with a broad host spectrum.

I have named certain new species for some collaborators on the Smithsonian Ceylonese Insect Project and others for some of the specialists who furnished identifications of prey, hosts, or parasites of Ceylonese solitary wasps.

5. Tiphia leclercqi, new species

This species is known only from a short series from Adams Peak, 1530–1770 m, an area of extremely heavy rainfall. It is closely related to T. oswini Turner and T. kaszabi, new species. The female of T. leclercqi differs in having a strong median crest on the lower front and in having the anterior escarpment of the scutum present only in the middle. The males of T. leclercqi and T. oswini are larger (6.0 mm long or more) than those of T. kaszabi (5.8 mm maximum length). The male of T. leclercqi has two interspaces on the upper front wider than an ocellus; these impunctate interspaces are lacking in T. oswini. Also, the lateral pronotal surface has only a few weak rugulae below instead of being strongly and closely rugulose on the lower half, and the apical margin of the clypeal lobe is more deeply emarginate, and the lateral angles are more acute and slightly upturned.

The paratypes are 6.0–7.0 mm long and agree very well with the allotype.

6. Tiphia kaszabi, new species

Tiphia kaszabi, known only from males, is most closely related to T. oswini Turner and T. leclercqi, new species, in having dark opaque tegulae rather than partly or entirely lighter, transparent tegulae as in other Ceylonese species with elongate tegulae. Tiphia kaszabi is smaller (5.8 mm maximum length) than its closest relatives (6.0 mm or longer), and the preapical impression of the first abdominal tergum has close, shallow elongate gouges rather than rounded punctures. The species is known from only three specimens from the Nuwara Eliya area.

Henry (Colombo), 1art is excluded from the type series because the head is lacking. A pair of paratypes has been deposited in the National Museums of Sri Lanka (Colombo), and a male paratype in the British Museum (Natural History).

Female paratypes are 6.1–6.5 mm long and agree well with the holotype in all essential details. Male paratypes are 3.8–5.1 mm long. Most males have the legs except coxae light red, but some specimens have brownish femora. The punctation is relatively less dense in some specimens, especially on upper front and mesopleuron, and somewhat more dense in a few.

8. Tiphia knutsoni, new species

The female of T. knutsoni is separated from the closely related T. hillyardi, new species, and T. bouceki, new species, by the infumated rather than light or deep-yellow wings. All three species have a strong frontal crest above antennae which distinguishes them from most other females with elongate tegulae. The male of T. knutsoni is the only one with elongate tegulae that also has a tuft of dense erect hair on the sixth abdominal sternum.

Both sexes of T. knutsoni key to T. tegelonga Allen in Allen's (1975) keys to Tiphia of the Indian subcontinent; however, the female of the latter species lacks a frontal crest, the punctures are smaller and much sparser on the head, pronotum, and mesopleuron, and the scutal escarpment and notauli are not connected. The male of T. tegelonga also is more sparsely punctate on the head, pronotum, and mesopleuron, and the stigma is two-thirds as long as the section of the costa beyond the stigma instead of only half as long.

Within Sri Lanka, T. knutsoni has been collected only in Udawattakele Sanctuary, Kandy, and Sinharaja Jungle in the Wet Zone. It occurs also in the Walayar Forest, South India.

ETYMOLOGY.—I am pleased to name this species for Lloyd V. Knutson, Insect Identification and Beneficial Insect Introduction Institute, U.S. Department of Agriculture, who has identified brachycerous Diptera prey of various Ceylonese sphecoid wasps.

10. Tiphia bouceki, new species

The female of T. bouceki is one of three species with elongate tegulae and a strong median crest on the lower front above the antennae. It differs from T. hillyardi, new species, in lacking strongly yellowish wings and in having dark antenna, tegula, and legs rather than light red. The light-yellow wings with amber veins and propodeal areola strongly narrowed posteriorly separate T. bouceki from T. knutsoni, new species, which has infumated wings with light-brown veins and a propodeal areola with apical width only slightly less than basal width. The male of T. bouceki lacks a tuft of dense erect hair on the sixth abdominal sternum, which separates it from T. knutsoni. It has a median carina on the lower front as does T. hillyardi, but it differs from that species in having only the fore and mid tibiae and tarsi red and the first abdominal tergum with the subapical impressed area two punctures in width.

Tiphia bouceki occurs primarily in the Dry Zone in Sri Lanka, but it occasionally enters the Wet Zone at moderate altitudes with medium rainfall. It occurs also in the Walayar Forest of South India. Three females and one male from Vavuniya were identified as T. decrescens Walker by Turner.

ETYMOLOGY.—The species is named for Zdenek Boucek, Commonwealth Institute of Entomology, London, our valued collaborator on Ceylonese Chalcidoidea.

11. Tiphia moczari, new species

This montane species is known only from a short series of females from the area around Nuwara Eliya in the Central Highlands. It shares with T. sakagamii, new species, the distinction of being the only small female with elongate tegulae that are transparent on the apical half, in having the legs light red except for the coxae, and in lacking a median crest on the lower front. Tiphia moczari is more sparsely punctate than T. sakagamii, having only a few scattered punctures on the upper front and on the mesopleural disk. It is presumed that the male will have similar coloration and also the very sparse punctation that is characteristic of some other montane species such as T. pulawskii, new species, and T. dayi, new species.

ETYMOLOGY.—The species is named for Laszlo Moczar, Szeged University, Hungary, collaborator on Mesitiinae (Bethylidae) and Ceropalinae (Pompilidae).

PARATYPES.—1art, same locality as holotype but 6–7 Feb 1979, K.V. Krombein, P.B. Karunaratne, T. Wijesinhe, S. Siriwardane, T. Gunawardane (USNM); 3art, Galway Natural Reserve, Nuwara Eliya, 6200 ft, 10 Jun 1978, P.B. Karunaratne, V. Kulasekare, L. Jayawickrema (USNM); 1art, Nuwara Eliya, 27–29 May 1975, D.H. Messersmith, G.L. Williams, P.B. Karunaratne (USNM). Paratypes have been deposited in the National Museums of Sri Lanka (Colombo) and in the British Museum (Natural History).

The paratypes are 6.5–7.3 mm long and agree in most details with the holotype. The median carina of the propodeal areola may be longer but it is never complete, and the ridge on the posterior propodeal surface may occur on the apical third.

12. Tiphia tsunekii, new species

This species is known only from the unique, newly emerged female holotype from Adams Peak, an area of very heavy rainfall. The specimen was resting quietly on a leaf of an herbaceous plant, probably waiting for a male to mate with her.

The female of T. tsunekii is readily recognized by a combination of the large size, short tegula, light red legs, nonsulcate hind basitarsus, inflated mid and hind tibiae, and moderately infumated wings. It is closest to T. gurneyi, new species, in size, dense punctation of head and thoracic dorsum, and inflated mid and hind tibiae but differs in having lighter red legs, suberect golden pubescence on head and thoracic dorsum, and in possessing a median carina on the propodeal areola.

ETYMOLOGY.—I am pleased to name this handsome species for my good friend and respected colleague Professor Katsuji Tsuneki of Mishima, Japan.

MALE.—Unknown.

13. Tiphia gurneyi, new species

The female is close to T. tsunekii, new species, and shares with it the large size, dense punctation of head and thoracic dorsum, short tegula, nonsulcate hind basitarsus, and inflated mid and hind tibiae. It differs from T. tsunekii in having only mid and hind femora and tibiae red rather than all legs except coxae, somewhat more infumated wings, a broader propodeal areola sometimes lacking the median carina, and in having cinereous rather than golden pubescence on head and thoracic dorsum.

The putative male of T. gurneyi also is large, has coarse punctation on head and thoracic dorsum, dark legs, lacks a tuft of erect hairs on sixth sternum, has a median ridge on hind tibia, and a weak subapical denticle on inner edge of mandible.

The holotype, allotype, and paratype female and most paratype males are from localities in the Wet Zone, but one paratype male is from the Dry Zone.

ETYMOLOGY.—The species is named for Ashley B. Gurney, a valued colleague for many years, to whom I am particularly grateful for numerous identifications of orthopterous prey of solitary wasps.

14. Tiphia nilgirensis Allen

FIGURES 58, 62

Tiphia (Tiphia) nilgirensis Allen, 1975:72, 73, pl. 6: fig. 39 [art; Nilgiri Hills and Coimbatore, South India; type in Leiden Museum].

Females of T. nilgirensis, T. palmi Krombein, and T. kurczewskii, new species, share with T. tsunekii, new species, and T. gurneyi, new species, the distinction of being the only five taxa with inflated mid and hind tibiae (2.0–2.5 times as long as broad). The females of these species also agree in having short tegulae and in lacking a median groove on the inner surface of the hind basitarsus and a submarginal carina on the propodeal dorsum. Tiphia nilgirensis, T. kurczewskii, and T. palmi are much smaller than T. tsunekii and T. gurneyi and more sparsely and delicately punctate. The former three species are easily separated because T. nilgirensis has dark legs and lacks a median groove on lateral pronotal surface, whereas the legs except coxae are red in T. palmi and T. kurczewskii.

The male of T. nilgirensis has dark legs, the sixth abdominal sternum lacks a tuft of dense erect hair, the inner surface of the hind tibia has a median ridge, and the mandible has a preapical denticle in unworn specimens.

The species occurs both in Sri Lanka and South India. In the former country it is found in both the Dry Zone and the Wet Zone and at altitudes near sea level to 2100 ft.

15. Tiphia kurczewskii, new species

The female of this species is another of the few with inflated tibiae, 2.0–2.5 as long as wide. It is smaller and more sparsely punctate than T. tsunekii, new species, and T. gurneyi, new species. It is similar to T. palmi Krombein in having the legs red except coxae but differs in having the apex of the pygidium delicately wrinkled and shagreened rather than smooth and glossy and in having the hind tibia less strongly inflated, with the length 2.5 times the width rather than 2.1 times.

The males of T. kurczewskii and T. palmi are among the four species in which the legs are entirely red except the coxae. These two species lack a tuft of dense suberect hair on the sixth abdominal sternum and a longitudinal ridge on the inner surface of the hind tibia. The former species differs from the latter in having the marginal cell extend farther toward the apex of the forewing than the second submarginal rather than having the two cells subequal in this respect. Also, in T. kurczewskii the lateral surface of the propodeum has closer weaker carinae on the posterior and upper areas.

Tiphia kurczewskii occurs both in Sri Lanka and South India. In the former country it is found mostly in the Dry Zone at rather low altitudes, although it is quite common in Colombo where the average annual rainfall is 2400 mm.

ETYMOLOGY.—The species is named for Frank E. Kurczewski, Syracuse University, New York, who has made substantial contributions to our ethological knowledge of solitary wasps.

Tiphia palmi Krombein, 1938:187 [new name for T. rufipes Smith, not Latreille, 1797].

Tiphia (Tiphia) rufipes Smith.—Allen, 1969:396–398 [type redescription]; 1975:63, 64 [description].

Tiphia palmi is the fifth species in which the mid and hind tibiae of the female are inflated. That sex is distinguished by its small size (5.9–7.0 mm long), relatively sparse punctation, the lack of a median groove on inner surface of the hind basitarsus, the lack of a submarginal carina on the dorsal propodeal surface, entirely light red legs except coxae, hind tibia only twice as long as wide, and the glossy pygidial apex. The male also has light red legs, the second submarginal cell extends as far toward the wing apex as the marginal cell, the mandible lacks a preapical denticle, and the margin of the clypeal lobe is truncate or slightly emarginate.

The species occurs throughout the Indian subcontinent. Within Sri Lanka it occurs in both the Dry Zone and the Wet Zone and at altitudes ranging from sea level to 1000 ft.

Tiphia (Tiphia) batorea Allen, 1975:34, 35 [art; Coimbatore, South India; type in Leiden Museum]. [New synonymy.]

This small species is relatively abundant and occurs chiefly in the Dry Zone in altitudes ranging near sea level to some 2000 ft. It occurs also in India as far north as Deesa.

I have examined the types of T. decrescens and T. batorea and find them to be conspecific. The syntype series of T. conscia Nurse consists of six females from Deesa, one collected in October 1898 and five in June 1901. These specimens have the wings weakly tinged with yellow, the tegula, tibiae, and tarsi usually reddish, and the hind margin of the propodeum testaceous. Most Ceylonese females have the wings infumated, lack the reddish tegula, tibiae, and tarsi and testaceous margin of the propodeum, but there are a few specimens having the coloration of Nurse's type series, and I have no hesitation in making this synonymy. I have selected one of the June 1901 specimens as lectotype because the 1898 specimen is aberrant in having three rather than five carinae composing the propodeal areola. Turner suggested that T. decrescens was the opposite sex of T. policarinata Magretti, 1892; I exclude the latter from the synonymy because I have not seen the type from Burma. Turner also synonymized T. nervosa Nurse under T. decrescens. M.C. Day informed me (in litt.) that there were two syntypes of T. nervosa in the British Museum (Natural History) but could locate only one in 1981. I have examined this syntype and find that it is not T. decrescens or any other species occurring in Sri Lanka. Accordingly, I have removed T. nervosa from the synonymy of T. decrescens pending study of the second syntype.

The sex association is based on the collection of both sexes together, though not in copula, on three different dates in Gampaha Botanic Garden, on two different dates in Kandy, and on one date in Padaviya.

Females are readily distinguished by the normal tegula, lack of a groove on the inner surface of the hind tibia, the inflated, broadened mid and hind tibiae, and the quinquecarinate propodeal areola. Males are recognized by the normal tegula, the tuft of dense, suberect setae on the sixth abdominal sternum, predominantly dark legs except reddish fore and mid femora and tibiae, and the lengthy marginal cell.

18. Tiphia bakeriana, new species

This is known from single male from the Induruwa Jungle, Gilimale, an area of lowland rain forest with heavy rainfall averaging 3900 mm annually. It is distinguished by the normal tegula, predominantly dark legs, tuft of dense suberect hair on the sixth abdominal sternum, by having the marginal cell extending farther toward the wing apex than the second submarginal cell, the dark tegula, and lack of a light red apical margin of the pronotal disk.

ETYMOLOGY.—The species is named for Edward W. Baker, Systematic Entomology Laboratory, U.S. Department of Agriculture, in appreciation of his many identifications of parasitic mites infesting Ceylonese and other solitary wasps and bees.

19. Tiphia weismani, new species

This species is known only from the unique female holotype from a low altitude in the Wet Zone with moderate rainfall. It is distinguished from other females which lack a groove on the inner surface of the hind basitarsus by the normal sized tegula, lightly infumated wings, almost entirely red legs, and sinuous submarginal carina on the propodeal dorsum.

Tiphia (Tiphia) petri Turner.—Allen, 1969:399, 400 [redescription and designation lectotype T. brevipennis]; 1975:71, 72 [description]

I have examined the unique male types of T. hirsuta, T. tarsata, and T. clypealis and can confirm Allen's synonymy of the latter two under T. hirsuta. The species is quite common in several localities in Sri Lanka and South India, but males show decreasing amounts of red in the latter areas suggesting that there is a north-south cline in the taxon. For example, the type of T. hirsuta has the following light red: mandible except apical third, apical two-thirds of clypeus, flagellum beneath, foretibia, and fore and mid tarsi; the tegula is entirely testaceous. Males from South India and Sri Lanka have the mandible and flagellum beneath darker red, the clypeus with a narrower reddened apical half or sometimes red only laterally, at most the foretibia and tarsus a darker red, but these segments sometimes brownish, and the tegula is brown on the inner anterior angle. The posterior marginal groove on the tegula is well developed in the type of T. hirsuta, weaker in the South Indian population and evanescent in Ceylonese specimens.

Allen (1975) described the sensorium of the hind tibia as almost threadlike, but this must be based on his Nepalese specimens, for the type of T. hirsuta has the sensorium quite broad toward the apex as in Ceylonese and South Indian males. Concerning the type of T. hirsuta, Allen (1969) noted that the propodeal areola was 1.3 times as wide at base as at apex and 2.75 times as long as apical width, and that the lower part of lateral surface of propodeum was aciculate. My examination of the type has the base of propodeal areola 1.5 times as wide as apex (range 1.5–1.8 in Ceylonese specimens) and the length 2.1 times the apical width (range 1.8–2.1 in Ceylonese specimens). Also, the lower part of lateral surface of propodeum has closer, finer rugulae than the upper part; this feature varies in the Ceylonese population from having the same sculpture to a condition where the lower part is mostly shagreened.

The association of sexes is based on the fact that both sexes are the most hirsute of the Ceylonese and South Indian fauna and on the capture of both sexes flying together at several localities in Sri Lanka and South India.

The Ceylonese and South Indian females agree in all essential details with the entire syntype series of T. brevipennis Cameron not Lucas, described from Barrackpore, Bengal, India, and collected by Rothney. The syntype series consists of two females in Oxford University and three females in the British Museum (Natural History). One specimen in Oxford bears a label in Cameron's handwriting, “Tiphia/brevipennis/Cam. Type/Barrackpore.” The other Oxford specimen bears only a small label with what appears to be “U” or “V”; another label added later by C. O'Toole states that the specimen was “in Rothney/Coll. under/Tiphia brevipennis/Cameron…/Almost certainly a/syntype because Rothney's/annotated reprint indicates/two specimens.” The three specimens in the British Museum (Natural History) all bear labels in Cameron's handwriting. One label is “Tiphia/brevipennis/Cam. Type/Bengal,” another is “Tiphia/brevipennis/Cam. Type,” and the third is “Tiphia/brevipennis/Cam./Bengal.” Allen (1969), unaware of the specimens in Oxford, treated the first specimen cited above as the lectotype, although he called it “holotype.” The lectotype must be selected from material in the Rothney collection, and I am designating as lectotype the specimen bearing Cameron's label with “type” written upon it. The specimen is not in the best condition, for the abdomen was broken off during shipment, and the vestiture is largely denuded. It is, however, clearly identical with the other syntypes.

The female is distinguished from any of its congeners in the Indian subcontinent by a combination of the strongly yellowish wings, comparatively denser and longer vestiture on the abdomen, lack of a groove on inner surface of hind basitarsus, complete anterior ridge on pronotal disk, and the lateral surface of the propodeum completely and closely obliquely rugulose. The male also is readily distinguished by the combination of the dark legs, conspicuous tuft of dense suberect setae on the sides of the sixth abdominal sternum, the higher posterolateral process on fifth sternum overlying a pocket-like depression, the longer apical fringes on the terga, and comparatively denser appressed vestiture on the clypeus and lower front.

Tiphia hirsuta has a wide range, occurring from northern India and Nepal southward into Sri Lanka. In the latter country the species is most common in Dry Zone areas and at low altitudes, but there are a few records from the Hill Country to an altitude of 2100 ft and with moderately heavy rainfall.

FEMALE.—Length 9.6–12.5 mm. Black, the following medium red: mandible except base and apex, scape and flagellum beneath, posterior margin of pronotal disk and tegula posterolaterally.

22. Tiphia wittmeri, new species

FIGURE 60

The female of T. wittmeri is distinguished by the lack of an anterior ridge on the first abdominal tergum, of a groove on inner surface of hind basitarsus, of a submarginal carina on the propodeal dorsum, and the dark legs and noninflated mid and hind tibiae. The male also lacks a ridge on the first tergum and a submarginal carina on the propodeal dorsum as well as lacking a median tuft of dense suberect hair on the sixth abdominal sternum and a ridge on the inner surface of hind tibia, the marginal cell extends farther toward wing apex than second submarginal, the tegula is testaceous and transparent on apical half, and short rugulae are lacking behind the anterior pronotal ridge. The sexes are associated on the basis of having been captured together, although not in copula, at several localities in the lowland rain forests at Kanneliya, Weddagala, and Gilimale, and also in the Dry Zone at Lahugala Sanctuary. The species appears to be quite common in lowland rain forests with high rainfall but occurs sparingly at several Dry Zone localities with lower rainfall. Several males were collected on foliage of kenda, Macaranga digyna (Wight) Mueller-Argovensis, presumably attracted by secretions from the extrafloral nectaries on the upper leaf surface near attachment of the leaf stem.

Tiphia (Tiphia) consueta Smith.—Allen, 1969:408, 409 [art; redescription of type]; 1975:87, 88 [redescription].

Tiphia consueta Smith occurs in both the Wet Zone and the Dry Zone from sea level to at least 2100 ft. The association of sexes is based on both having been taken together at several localities, including a pair in copula, and on the fact that both have a complete median carina on the posterior surface of the propodeum.

Bingham's syntype series of M. nigra consisted of two specimens from Pundaloya (correctly Pundaluoya) collected by Green and three specimens in his collection from various parts of Tenasserim. Undoubtedly it is a mixed series, for I am not aware that any Ceylonese species occurs in Tenasserim. There are no specimens of Tiphia from Pundaluoya in the British Museum (Natural History), Zoologisches Museum (Berlin), or National Museums of Sri Lanka (Colombo), nor in the Ministry of Agriculture collection, Sri Lanka, where Green was employed. Bingham's identification label is now inexplicably on a male Tiphia from Aden in the British Museum (Natural History); this specimen cannot be part of Bingham's type series, for the tegulae are elongate, whereas Bingham's illustration is of a male with short tegulae. There are two unidentified Tiphia males from Tenasserim in the British Museum (Natural History) and the Zoologisches Museum (Berlin). Either or both may be syntypes of M. nigra, but designation of one as lectotype should await a revisionary study of the fauna of Tenasserim based on quantities of material as yet uncollected. I would prefer to designate one of the two Pundaluoya specimens as lectotype if either is ever found. Undoubtedly, it would be a senior synonym of one of my new species but would not take precedence inasmuch as T. nigra (Bingham) is preoccupied.

I believe it is unlikely that Bingham's male can be the opposite sex of T. consueta. The village of Pundaluoya is in a valley at about 3500 ft surrounded by hills of at least 4000 ft, and I have never collected T. consueta at more than 2100 ft. I collected at Pundaluoya for an hour in April 1981 but obtained no Tiphia.

Both sexes of T. consueta have a normal tegula, lack a transverse carina on the first abdominal tergum, have predominantly or entirely dark legs, and have a complete median ridge on the posterior propodeal surface. In addition, the female has a median groove on the inner surface of the hind basitarsus, and the legs are entirely dark except for the narrow apices of the tarsal segments. The male has a long marginal cell, lacks a preapical denticle on the inner surface of the mandible, has a median ridge on the inner surface of the hind tibia, and the preapical impression of the first abdominal tergum has subcontiguous punctures.

27. Tiphia hirashimai, new species

FIGURES 43, 45, 47, 49, 59

Tiphia hirashimai is the largest known Ceylonese Tiphia (art, 11.6–15.1 mm; art, 6.5–8.4 mm). The female is readily separated from those of all other Ceylonese species except T. dayi, new species, and T. fennahi, new species, by the bright-red mid and hind femora. In addition to being larger than those two species, T. hirashimai has a much more densely punctate front, and the clypeus has an evenly and broadly rounded apical margin. The male is distinguished by the predominantly black legs, lack of a tuft of dense suberect hair on the sixth abdominal sternum, the marginal cell extending farther toward apex of forewing than the second submarginal, the opaque, shagreened tegula, the median ridge on inner surface of hind tibia, the preapical denticle of the mandible, and the relatively very broad first abdominal tergum with weak and finely punctate preapical impression.

The species is known from a number of specimens from localities in a circumscribed area of the central Hill Country of the Wet Zone and seems to be abundant only in Kandy.

ETYMOLOGY.—I take pleasure in naming it for my colleague Yoshihiro Hirashima, Kyushu University, Fukuoka, Japan, collaborator on Ceylonese Nomiinae and Ceratininae.

A pair of paratypes has been deposited in both the National Museums of Sri Lanka (Colombo) and British Museum (Natural History).

FEMALE paratypes are 11.6–15.1 mm long and agree in most details with the holotype, except that lateral pronotal surface below groove may be obliquely rugulose, lower anterior area of lateral propodeal surface may have some dense, fine punctures, tegula may be 1.4 times as long as broad, head width may be 1.9 times as great as interocular distance at fore ocellus, and basal width of propodeal areola may be 1.5 times apical width. Male paratypes are 6.5–8.4 mm long and agree in most details with the allotype, but the head width may be 1.8 times the interocular distance, the lower front may have a median ridge, the tegula may be only 1.1 times as long as broad, the basal width of the propodeal areola may be 1.6 times as great as apical width, and in large specimens the first abdominal segment may be only 1.1 times as long as broad, and the clypeal lobe only 1.5 times as wide as antennal fossa.

28. Tiphia dayi, new species

?Tiphia rufo-femorata Smith.—Bingham, 1896:431 [art; Pundaloya, Ceylon; misidentification].

Tiphia rufofemorata Smith does not occur in Sri Lanka. Considering the altitude and locality, it is probable that Bingham misidentified as T. rufofemorata a female of the species described here as T. dayi. It is the only female with red femora that is likely to occur at Pundaluoya.

Tiphia dayi, T. fennahi, new species, and T. hirashimai, new species, are unique in the Ceylonese fauna in that the females have light-red mid and hind femora and a median groove on the inner surface of the hind basitarsus. The female of the latter species is considerably larger than the former two and is also easily distinguished by having the clypeal margin broadly and evenly rounded rather than having a relatively narrow median lobe extending beyond the rest of the margin.

Tiphia dayi occurs most commonly at higher altitudes and is rarely found below about 2000 ft elevation, whereas T. fennahi is more common at low altitudes and is not found higher than 2200 feet. Typical females of the two species are normally separated without difficulty because those of T. dayi are usually more sparsely punctate, having several impunctate areas on the upper front wider than an ocellus, many discal punctures on the mesopleuron separated by one to several times the diameter of a puncture, and the subapical band of punctures on the first abdominal tergum only one puncture wide across the middle. Females of T. fennahi are usually more densely punctate, the upper front with smaller and fewer impunctate interspaces, mesopleural punctures separated at most by the width of a puncture, and the preapical band of punctures of first tergum two punctures wide across the middle; however, the frontal and mesopleural punctation is occasionally denser in T. dayi, particularly at lower altitudes such as Udawattakele Sanctuary, Kandy, and the two species must then be separated by the preapical punctation on first tergum.

The males of T. dayi and T. fennahi have the legs predominantly dark, the sixth abdominal sternum without a tuft of dense suberect hair, the marginal cell extending farther toward apex of forewing than the second submarginal, the tegula dark, opaque, and normal in size, the inner surface of the hind tibia usually without a longitudinal ridge or narrow smooth strip, and the mandible with a preapical denticle on the inner margin. Males of these species are readily separated from each other by the shape of the first abdominal segment, which is 1.3–1.4 times as long as broad in T. dayi and 1.1 times as long as broad in T. fennahi, by the erect vestiture of the body, which is black in the former species and silvery, cinereous or light brown in the latter, and by the usually relatively sparser punctation of T. dayi.

ETYMOLOGY.—The species is named for Michael C. Day, British Museum (Natural History), London, collaborator on Ceylonese Pompilinae.

Badulla District: 1art, Badulla, 3000 ft, 14 Apr 1922, G.M. Henry (Colombo). Omitted from the type series are 1art, Ceylon, #6091, Nietner (Berlin) because the abdomen is lacking, 1art, Kitulgala (USNM) because the head is lacking, and 1art, Yatiyantota, Kegalla Dist. (Colombo) because it is very moldy. Paratypes have been placed in the National Museums of Sri Lanka (Colombo) and British Museum (Natural History).

Female paratypes are 6.9–10.6 mm long. The density of punctation is variable, the most densely punctate specimens having the upper front with only two impunctate interspaces as wide as an ocellus and most punctures on upper front separated by less than the width of a puncture, the pronotal disk similarly punctate, and the mesopleural disk with many punctures separated at most by half the diameter of a puncture; the punctation of the preapical impression of the first abdominal tergum, however, is quite constant. Male paratypes are 4.5–7.6 mm long. The following differences are noteworthy: vestiture may be brown in older specimens or those from lower elevations; mid tibia may be reddish beneath; the punctation is sometimes relatively denser; the inner surface of hind tibia may have a smooth median streak or ridge; and the first abdominal segment is 1.3–1.4 times as long as broad.

29. Tiphia fennahi, new species

Both sexes of T. fennahi resemble rather closely those of T. dayi, new species, the preceding species. Females of the present species are usually more closely punctate than those of T. dayi. The few females of the latter species with denser punctation on the head and thorax can be distinguished from those of T. fennahi by having the preapical band of punctures on first abdominal tergum 1 puncture wide across the middle rather than 2. Males are more easily distinguished, because those of T. fennahi have silvery, cinereous, or light-brown erect vestiture rather than black, and the first abdominal segment 1.1 times as long as broad rather than 1.3–1.4 times as in T. dayi. Furthermore, T. fennahi is common at low altitudes ranging upward to 2200 ft, whereas T. dayi is found from 2000 to 6200 ft. Tiphia fennahi occurs in both the Dry Zone and the Wet Zone, whereas T. dayi is restricted to the Wet Zone.

30. Tiphia wahisi, new species

This small species is known only from a short series of males taken in a Malaise trap near Wilpattu National Park in the Dry Zone and from a single male from a Malaise trap at Deniyaya in the Wet Zone. The characters which distinguish it are the normal tegula, second submarginal cell extending almost as far toward apex of forewing as the marginal cell, the lack of a tuft of dense erect setae on the sixth abdominal sternum, the mostly longitudinally oriented posterolateral process of the fifth sternum, and the light-reddish tarsi and antennal flagellum beneath.

The paratypes are 4.9–6.1 mm long and are otherwise very similar to the holotype.

31. Tiphia sabroskyi, new species

This species is known from a short series of males mostly from localities in the Dry Zone. It is very similar to the male of T. wittmeri, new species, a taxon which occurs mostly in the Wet Zone and quite sparingly in the Dry Zone. The male of T. sabroskyi may be distinguished by the normal tegula that is transparent except for inner anterior area, the second submarginal cell of the forewing not extending so far toward the apex as the marginal cell, absence of entirely red legs, lack of a tuft of dense erect hair on sixth abdominal sternum, presence of short rugulae behind anterior pronotal ridge, a sinuous submarginal ridge on dorsal propodeal surface, and the extremely sparse oblique rugulae on upper section of lateral propodeal surface.

ETYMOLOGY.—The species is named for Curtis W. Sabrosky, Systematic Entomology Laboratory, U.S. Department of Agriculture (retired), who has furnished identifications of some dipterous prey of Ceylonese solitary wasps.

HOLOTYPE.—art, Sri Lanka, Central Province, Kandy District, Hasalaka, 107 m, 16–19 Feb 1977, 1977, K.V. Krombein, P.B. Karunaratne, P. Fernando, D.W. Balasooriya (USNM Type 100280).

MALE.—Length 6.9 mm. Black, the following light red: mandible in middle, flagellum beneath, apex narrowly of all femora, fore and mid tibiae and tarsi, narrow apices of hind tibia and tarsal segments; tegula testaceous and transparent except inner anterior area opaque and dark. Vestiture white except apex of abdomen slightly yellowish. Wings clear, stigma black, veins light brown.

Head width 1.6 times interocular distance at anterior ocellus; mandible without preapical denticle on inner margin; clypeal lobe relatively narrow, 1.3 times as wide as antennal fossa, margin subtruncate, lateral angles rounded; lower front with contiguous small punctures, median ridge lacking; upper front with a narrow impunctate strip below anterior ocellus, punctures separated by 1 to 2 times the width of a puncture except several rows of contiguous punctures along eye margin, no impunctate interspaces as wide as an ocellus.

First abdominal segment 1.1 times as long as broad; preapical impression of first tergum shallow, with rather large punctures 1 puncture wide across middle and 2 punctures wide laterally; posterolateral process of fifth sternum low, arcuate, mostly transversely oriented; sixth sternum without tuft of dense suberect hair.

FEMALE.—Unknown.

PARATYPES.—EASTERN PROVINCE. Trincomalee District: 1art, China Bay, 0–100 ft, in Malaise trap, 27–31 Jan 1977, K.V. Krombein, P. Fernando, D.W. Balasooriya, V. Gunawardane (USNM). WESTERN PROVINCE. Colombo District: 1art, Gampaha Botanic Garden, 14 Jan 1977, K.V. Krombein, P. Fernando, D.W. Balasooriya, V. Gunawardane (USNM). UVA PROVINCE. Badulla District: 2art, Bandarawela, 7 Apr 1931, G.M. Henry (Colombo); 1art, Diyatalawa, Jun 1904 (Colombo). SOUTHERN PROVINCE. Hambantota District: 1art, Katagamuwa, 7–11 Feb 1936, G.M. Henry (Colombo). A paratype has been deposited in the National Museums of Sri Lanka (Colombo).

PARATYPES are 5.2–6.6 mm long. They are quite similar to the holotype in most details, but the mid tibia is sometimes infuscated on outer surface, the mandible may have a weak preapical denticle, the smooth area below fore ocellus may be lacking, and the margin of the clypeal lobe may be slightly emarginate.

Subfamily MYZININAE

This group is represented in Sri Lanka by five species of Mesa Saussure and two species of Hylomesa Krombein. One new species of Mesa and one new species of Hylomesa are known only from Sri Lanka; a second new Mesa occurs also in South India. The remaining four species were all described earlier, the three species of Mesa occurring in India also, and the one species of Hylomesa occurring through India and Southeast Asia to the Philippines.

Mesa was proposed as a genus by Saussure; later authors treated it as a subgenus of Plesia or Elis. Later Krombein (1937) re-elevated Mesa to generic rank. Myzine dimidiata Guérin, M. petiolata Smith, and M. claripennis Bingham are all transferred to the genus Mesa for the first time and are listed as new combinations therein.

Females of the four smaller species of Mesa (karunaratnei, new species, flavipennis, new species, petiolata, and claripennis) are similar in most details of coloration, vestiture and sculpture, as are the males of the same species. To conserve space I have described only M. karunaratnei in detail. Descriptions of the other three species are limited to a listing of the characters in which each differs from M. karunaratnei.

Hosts of the Ceylonese Mesa are unknown but are presumed to be larvae of scarabaeid beetles in the soil, because the legs of the female Mesa are strongly modified for fossorial use. Hylomesa longiceps (Turner) has been bred in India from the larva of a cerambycid beetle dwelling in timber. Presumably the new Hylomesa parasitizes such larvae also, because all specimens were captured while flying around dead standing or fallen tree trunks.

In addition to being the largest Ceylonese Mesa, it differs at once from other species in the female having the abdomen red on basal segments instead of being entirely black and in the male having most of the forewing dark, the abdomen black without yellow bands, and the pronotal disk margined anteriorly by a strong ridge. It is rather rare in Sri Lanka and appears to be restricted to Dry Zone areas below 2000 feet.

Black, the following cream: basal two-thirds of mandible, transverse bar on clypeal lobe, apex of antennal tubercles, base of tegula, and upper surface of foretibia and tarsus; posterior margin of pronotum testaceous. Apical two-thirds of forewing and apical third of hind wing strongly infumated. Erect vestiture whitish to cinereous, short on abdomen, longer on head and thorax.

Median lobe of clypeus gently emarginate at apex, lateral tooth small, rounded; front coarsely, contiguously punctate; ocelli in a low triangle, posterior pair margined behind by a row of shallow punctures, postocellar distance subequal to ocellocular distance and 0.62 times ocelloccipital distance; vertex with small punctures separated by at least the diameter of a puncture.

Pronotal disk margined anteriorly by a transverse ridge, behind this with moderate, subcontiguous punctures, laterally with longitudinal rugae on lower half which extend upward on anterior part, remainder of surface with scattered small punctures; scutum mostly with scattered punctures a bit larger than on pronotal disk; scutellar disk with coarser contiguous to subcontiguous punctures; mesopleural disk with contiguous punctures of same size as scutellar disk; dorsal surface of propodeum with contiguous smaller punctures except for a smooth area on each side behind spiracle; lateral surface with a narrow area of contiguous punctures above, elsewhere with oblique rugae; posterior surface with contiguous smaller punctures than on dorsal surface.

33.Mesa Karunaratnei, new species

Figure 14

The male of this species is unique among Ceylonese Myzininae in that the seventh tergum does not have a flattened pygidial area but has the dorsum slightly convex. The female has the forewing and veins strongly yellow as does M. flavipennis, new species. It is distinguished from that species by the sparse punctation of the front and virtually impunctate scutum.

The majority of the type series was captured in the garden of the Colombo Museum by P.B. Karunaratne, former curator in entomology, between 7:30 and 9:00 A.M. Females were crawling on the ground, and the males were flying low over the ground searching for females. Three males were collected while attempting to mate with newly emerged females on the ground. Two other males attempted to mate on the ground with a newly emerged female and male of Tiphia hirsuta Smith.

ETYMOLOGY.—I am pleased to name the species for P.B. Karunaratne, collector of most of the specimens and my companion during many collecting trips in his country.

MALE.—Length 12.3 mm, forewing 7.2 mm. Black, abdomen with faint blue reflections, the following lemon yellow: palpi, mandible except apex, clypeus, frontal tubercles, band on posterior half (middle) to third (side) of dorsal surface of pronotum and anterior angle of lateral surface, tegula, apex of mesosternum, narrow bands at apices of first to sixth abdominal terga, anterior margins of second to sixth bi-emarginate, tiny posterolateral spots on second to fifth sterna, fore and mid coxae beneath, apical half of forefemur, apical third of mid femur, apical sixth of hind femur, fore and mid tibiae externally, basal two-thirds of hind tibia, and all tarsi except apical segment. Wings clear, veins medium brown, stigma darker. Erect vestiture silvery, relatively dense but not long on head and thorax, shorter and sparser on abdominal dorsum; abdominal sternum with suberect short, relatively sparse setae.

Median lobe of clypeus gently emarginate at apex, lateral teeth small, rounded, and separated from each other by the diameter of first flagellar segment; front contiguously and finely pitted except for small smooth area in front of fore ocellus; ocelli in a low triangle, postocellar distance 1.1 times the ocellocular distance and 0.8 times the ocelloccipital distance, hind ocelli not margined by a punctate groove; vertex with punctures behind ocelli separated by about the diameter of a puncture and by about half the diameter of a puncture laterally; flagellum long and filiform, segments not noticeably widened toward apex.

PARATYPES.—8art, 7art, same label data as holotype (USNM); 2art, Colombo, 30 Sep 1924, at light, and 5 Oct 1938, G.M. Henry (Colombo); 1art, Colombo, 6 Sep 1966, P.B. Karunaratne (Ottawa). NORTH WESTERN PROVINCE. Puttalam District: 2art, Deduru Oya, 5 Mar 1958, R.L.A. Perera (Lawrence). MISCELLANEOUS. 1art, Ceylon, Nietner (Berlin). Paratypes of both sexes have been deposited in the National Museums of Sri Lanka (Colombo) and British Museum (Natural History). Male paratypes are in the Zoologisches Museum (Berlin), University of Kansas, and Canadian National Collection.

Female paratypes are 10.0–10.6 mm long and differ very little from the holotype; some specimens have the narrow apical rim of the pygidium delicately shagreened. Male paratypes are 9.6–13.0 mm long and agree with the allotype in all important details. The yellow spots on abdominal sterna are smaller in a few specimens and entirely lacking in one male which also has narrow bands on the terga.

34. Mesa flavipennis, new species

Figure 13

The females of M. flavipennis and M. karunaratnei, new species, are unique among the Ceylonese species in having the forewing strongly yellowish and with yellow veins. The female of M. flavipennis differs from M. karunaratnei in being comparatively more densely punctate especially on upper front, scutum, and scutellum and in having the apices of the second to fourth or fifth abdominal terga narrowly reddened. The males of M. flavipennis, M. karunaratnei, and M. petiolata (Smith) have long, filiform antennal flagella; M. flavipennis is readily distinguished from the latter two species by having the front with separated punctures instead of being contiguously pitted.

The type series was captured in several Dry Zone localities at altitudes not over 500 ft and on both the east and west coasts. Several males have been collected also in South India.

ETYMOLOGY.—The specific name is from the Latin flavus (yellow) plus penna (feather), in allusion to the strongly yellowish forewings of the female.

HOLOTYPE.—art, Sri Lanka, Southern Province, Hambantota District, Palatupana, 3–6 Feb 1975, K.V. Krombein, P.B. Karunaratne, P. Fernando, E.G. Dabrera (USNM Type 100282).

FEMALE.—Length 9.4 mm, forewing 5.5 mm. Black, mandible except apex, tegula, apices of tarsal segments and narrow apical bands on second to fifth abdominal segments dark red. Forewing membrane and veins strongly yellow, hind wing clear with testaceous veins. Erect vestiture glittering white.

Other details as noted for M. karunaratnei except as follows.

Frontal groove not well developed, its location marked by a row of subcontiguous punctures, upper half of front with punctures medially and laterally so that there are only 2 relatively small smooth areas; postocellar distance 0.8 times ocellocular distance and 0.7 times ocelloccipital distance; vertex laterally with some punctures separated by half the diameter of a puncture.

Pronotal disk with only a narrow median impunctate strip; scutum more closely but very sparsely punctate; scutellum with many of punctures separated by not much more than the diameter of a puncture.

Narrow apical margin of pygidium strongly shagreened.

ALLOTYPE.—art, same label data as holotype (USNM).

MALE.—Length 11.5 mm, forewing 6.2 mm. Coloration, vestiture, and other details as noted for M. karunaratnei except as follows.

Erect vestiture on abdominal dorsum denser.

Front with subcontiguous punctures; postocellar distance 0.9 times ocelloccipital distance; most punctures on vertex separated by half the diameter of a puncture.

Petiole of first abdominal segment 0.6 times as long as nodose posterior section of first tergum; second to fifth terga with smaller punctures mostly separated by about the diameter of a puncture; pygidial area of seventh tergum flattened, ovoid, central ridge higher than lateral carinae, surface between these with a row of punctures, apex not emarginate; genitalia of paratype (Figure 13).

Paratypes of both sexes have been deposited in the National Museums of Sri Lanka (Colombo) and British Museum (Natural History), and male paratypes are in the Canadian National Collection, the Natural History Museum in Basel, and the Oregon State University Collection, Corvallis.

Female paratypes are 7.8–10.4 mm long and are very similar in most details to the holotype except that three have only a narrow polished streak rather than a median groove on dorsum of propodeum, and four lack the narrow reddened apices on the abdominal segments. Male paratypes are 8.0–12.3 mm long and agree in all important details with the allotype. The pale markings on five specimens are ivory rather than yellow, and the smallest specimen from near Kokmotte Bungalow is more sparsely punctate, noticeably so on the head.

35.Mesa claripennis (Bingham), new combination

FIGURES 5,6, 11

Myzine claripennis Bingham, 1897:68 [art; Burma, Tenasserim; type in British Museum (Natural History)].—Nurse, 1902:82 [art, differentiated from M. hortata Nurse in key].

Myzine hortata Nurse, 1902:81, fig. 6 [art; Deesa; location of type unknown but probably unlabeled as type in British Museum (Natural History)].

Plesia (Mesa) hortata (Nurse).—Turner, 1908a:512 [art; Deesa and Pusa, Bengal].

Elis (Mesa) claripennis (Bingham).—Turner, 1912:718 [art, art; Burma, Ceylon, Bengal, Deesa; synonymizes this and M. hortata Nurse and describes art].

I have examined Bingham's type of M. claripennis and find that it agrees in all essential details with the Ceylonese population described below. The Nurse collection is in the British Museum (Natural History), but there is no specimen bearing a label “M. hortata.” Nurse's description agrees with M. claripennis, and I accept Turner's synonymy of M. hortata under M. claripennis. M.C. Day believes that Nurse may have removed the label from his type when Turner made the synonymy in 1912 and that an unidentified specimen from Deesa, 9–01, may be the actual type. I have a female of M. claripennis in my collection from Deesa, 11–01, sent to me in exchange many years ago by R.E. Turner. Turner sent it and two males also from Deesa identified as M. petiolata (Smith), but both sexes agree with his (1912) key characters for M. claripennis. The two males belong to two species, and neither agrees in genitalia with either M. claripennis or M. petiolata. One male of M. claripennis in the National Museums of Sri Lanka (Colombo) was identified by Turner as M. petiolata, and another was identified by him as the probable male of M. ceylonica.

Mesa claripennis is almost as widely distributed in Sri Lanka as M. petiolata. Like that species it occurs from sea level to at least 2100 ft and in both Wet and Dry Zone areas, although it is much more abundant in the Dry Zone. It also is widely distributed in the rest of the Indian subcontinent (I have seen specimens from Coimbatore and Kodaikanal in South India as well as from Deesa), and it has been recorded from Pusa in Bengal, Burma, and Tenasserim. Dates of collection in Colombo suggest that the species may breed throughout the year.

Mesa claripennis is unique among Ceylonese males in that the antennal flagellum is reddish beneath, relatively shorter, and with the segments toward apex becoming gradually broader so that the flagellum has a slightly clavate appearance. The female is the only species with the wings weakly yellowish and with the median lobe of the clypeal margin broadly rounded instead of being subtruncate and weakly tridentate.

FEMALE (Figure 6).—Length 8–10.5 mm, forewing 6.2–7.0 mm. Black, mandible except base and apex and tegula at apex reddish, apices of tarsal segments brownish. Forewing membrane slightly yellowish, hind wing clear, veins amber. Erect vestiture glittering white, slightly tinged with yellowish on head.

Other details as noted for M. karunaratnei, new species, except as follows.

Apex of clypeal lobe gently rounded; upper half of front with most punctures separated by once to twice the diameter of a puncture; postocellar distance 0.6 times ocellocular distance and 0.5 times ocelloccipital distance; hind ocelli margined behind by a row of punctures but not grooved; punctures on vertex separated by the diameter of a puncture or less.

Pronotal disk with punctures as small as on front, separated by about half or more the diameter of a puncture; side of pronotum on lower half obliquely striate or the striae evanescent; scutum with a few more scattered punctures.

MALE (Figure 5).—Length 7.5–12.0 mm, forewing 5.1–6.7 mm. Coloration, vestiture, and other details as in M. karunaratnei except as follows.

Suberect vestiture on abdomen relatively denser.

Median lobe of clypeus more shallowly emarginate, lateral angles broadly rounded not dentate; postocellar distance 0.6 times the ocellocular and postocellar distances; hind ocelli occasionally margined behind by a very shallow punctate groove; punctures on vertex separated by half the diameter of a puncture; flagellum shorter, segments on apical half becoming slightly wider toward apex so that flagellum appears somewhat clavate.

Elis (Mesa) petiolata (Smith).—Turner: 1912:717, 718 [art, art; Bengal, Bombay, Ceylon].

Smith's syntype series in Oxford University consists of two males, each bearing a hand-written label “Ind.” The genitalia are identical with specimens from Sri Lanka and South India except that the dorsal edge of the cuspis is a bit more strongly curved. The punctation of front and dorsum of propodeum, conformation of antenna, and coloration of forecoxa are similar except that one syntype has the apex of forecoxa with a tiny yellow spot. One syntype has a larger creamy area on forefemur than any other specimens; the other syntype has an apical band on the second tergum divided into three spots, and that on the sixth tergum is absent on the sides. I have selected as the lectotype the larger specimen (11 mm) with greater extent of creamy markings. Its genitalia were split to facilitate examination of the internal surface.

I have examined the type of M. ceylonica Cameron and, based on Ceylonese material, I agree with Turner's association of sexes in this species.

Both sexes of M. petiolata are easily distinguished from the other Ceylonese species of Mesa. The dark wings of the female separate it from all but the larger M. dimidiata (Guérin), which differs in having several of the abdominal segments red; also the punctures on dorsal surface of pronotum and posterior surface of propodeum are coarser and closer in M. petiolata. The males of M. petiolata and M. dimidiata are the only Ceylonese Mesa with black forecoxae; the larger size, infumated wings, and black abdomen readily separate the latter from the former species.

Mesa petiolata is widely distributed in Sri Lanka from sea level to at least 2100 ft and in both Dry and Wet Zone areas, although it is much more common in the Dry Zone. It occurs also in India. I have seen specimens from Karikal in Pondichery State, and Walayar Forests in Kerala State and Coimbatore, and it has been recorded from Pusa, Bombay, and Barrackpore. Dates of collection in Colombo suggest that the species may breed throughout the year.

FEMALE.—Length 7.8–10.2 mm, forewing 5.0–6.5 mm 20786 6.5 mm. Black, mandible except apex and tegula dark red. Forewing strongly yellow and with yellow veins on basal third, apical two-thirds strongly infuscated and with brown veins, hind wing clear on basal half, slightly infumated on apical half. Erect vestiture glittering white, slightly tinged with yellow on head.

Other details as noted for M. karunaratnei, new species, except as follows.

Median third of upper half of front smooth, the third adjacent to eye subcontiguously punctate; postocellar distance 0.8 times the ocellocular distance and 0.6 times the ocelloccipital distance; vertexal punctation denser, some punctures separated by half the diameter of a puncture, others more separated.

Pronotal disk with punctures somewhat larger and tending to be confluent in longitudinal rows, the central rows separated by about the diameter of a puncture, rows on sides by half the diameter of a puncture; scutum smooth anteriorly in middle, laterally and posteriorly with a few punctures separated by about the diameter of a puncture; scutellum with punctures in middle separated by the diameter of a puncture, laterally by half the diameter of a puncture; mesopleural disk with punctures separated by half the diameter of a puncture.

Narrow apical margin of pygidium shagreened.

MALE (Figure 12).—Length 10.0–14.0 mm, forewing 6.0–8.0 mm. Coloration, vestiture, and other details as noted for M. karunaratnei except as follows.

Pale markings creamy, base of clypeus black, lateral surface of pronotum not spotted, bands on abdominal terga narrower, that on first sometimes separated on midline, that on sixth occasionally separated into 3 spots, some spots on sterna occasionally lacking, coxae all black as is hind femur, fore and mid femora pale at extreme apex, and only basal third of hind tibia pale. Erect vestiture on abdominal dorsum denser.

Apical emargination of clypeal lobe a bit deeper, the teeth more prominent, separated from each other by 0.8 times the diameter of first flagellar segment; postocellar distance 0.8 times both ocellocular and ocelloccipital distances, hind ocelli margined behind by a shallow depression; punctures on vertex separated by half the diameter of a puncture.

Propodeal dorsum finely, irregularly and closely rugulose-reticulate, lateral and posterior surfaces more delicately so.

Petiole of first abdominal segment 0.4 times as long as nodose section of first tergum; second to fifth terga with small punctures separated by about the diameter of a puncture; pygidial area of seventh tergum flattened, ovoid, central ridge higher than lateral carinae, surface between these with a row of punctures, apex not emarginate; genitalia (Figure 12).

Hylomesa longiceps (Turner).—Krombein, 1968:12–15, fig. 1, pl. 1: fig. 1 [art, art; Ceylon, India, Assam, Burma, Malaysia, Philippines].

This handsome species is readily distinguished from its only Ceylonese congener, H. anomala, new species, by the characters listed in the foregoing key. All species of the genus are collected rather uncommonly, and I suspect that this is due to their being primarily arboreal creatures. Presumably they prefer to parasitize beetle prey in dead standing timber rather than in wood on the ground.

Hylomesa longiceps is noteworthy in that it is the most widely distributed species of the genus with records of capture in Sri Lanka, India, Assam, Burma, Malaysia, and the Philippines. Within Sri Lanka it occurs both in the Dry Zone forests and in areas of moderate rainfall.

It is also the only Hylomesa for which we have any information on host preferences. Turner (1912) stated that T.R. Bell “informed me that he bred this species from the larva of a longicorn beetle.” This statement is at variance with the label data on the only female H. longiceps bearing a Bell label: “in dead wood with longicorn larvae 14–1–07.”

FEMALE.—Length 15–23, forewing 10–16 mm. Black, head except apex of mandible and hypostomal area and occasionally the ocellar triangle, varying from light to dark red; scape, pedicel, and from 1 to 4 of basal flagellar segments also red; abdomen occasionally with metallic blue reflections; forewing entirely infumated or with basal area lighter in some specimens, the darkened area with violaceous reflections.

Head elongate, from above with length (apex of antennal insertions to occiput) subequal (0.94–1.0) to width across eyes; in larger specimens the sides of head are somewhat rounded out behind eyes so that eyes are not so protuberant as in smaller specimens; clypeal keel weak, present only on basal half or two-thirds, clypeal margin with median teeth weak, slightly separated; median frontal sulcus extending halfway to anterior ocellus; front with punctures moderate in size and contiguous or almost so; vertex with more scattered punctures on anterior third and almost impunctate on posterior two-thirds; ocellocular distance 2.17–2.43 times the postocellar distance and 0.42–0.44 times the ocelloccipital distance; anterior ocellus closer to apices of antennal tubercles than to occiput; head beneath with rounded posterolateral angles; distance between occipital and hypostomal carinae subequal to length of hypostomal area.

Anterior margin of pronotal disk strongly ridged, anterior half with coarse, confluent to subconfluent punctures arranged in longitudinal rows; scutum with subconfluent, coarse punctures except posteriorly somewhat more crowded; scutellum with punctures separated by half or more the diameter of a puncture but more crowded posteriorly; inferior margin of hind femur obtusely angulate near apex; apex of hind tibia on inner surface without heavy, flattened, short setae; punctures small on areas adjacent to cuneate space on propodeum, the disk posteriorly and laterally with larger, subconfluent pits; posterior surface of propodeum with mostly confluent or subconfluent pits.

Disk of first tergum strongly ridged anteriorly; last tergum shagreened on apical fourth.

MALE.—Length 12–17 mm, forewing 7–12 mm. Color as in female except that venter of head occasionally is all black and as many as 6 flagellar segments may be red.

Clypeal keel strong, present on basal two-thirds or three-fourths; median lobe of clypeus with a shallow emargination separating the 2 well-developed teeth; distance from apex of frontal platform to occiput 0.85–0.87 times the width across eyes; front with mostly contiguous to subcontiguous pits; vertex with smaller, more scattered punctures; ocellocular distance 1.9–2.8 times the postocellar distance and 0.59–0.71 times the ocelloccipital distance; occipital carina weak or evanescent dorsally; median flagellar segments 1.4–1.5 times as long as wide.

Pronotal disk anteriorly with a strong ridge, behind that with weak to strong punctures, sometimes rather scattered, sometimes arranged almost contiguously in a few transverse rows; scutum and scutellum with coarse, shallow, contiguous to subcontiguous pits; mesopleural disk with very coarse, contiguous to scattered pits; metapleuron usually without ridges above but occasionally with a few weak ridges; propodeal dorsum irregularly rugulose, the narrow median channel with a few transverse rugae, the posterior margin strongly ridged; lateral surface with a few strong rugae anteriorly, the rest of surface with coarse contiguous pits or irregularly rugulose; posterior surface varying from contiguously pitted to irregularly rugulose.

First tergum with strong transverse ridge anteriorly, the disk with scattered large punctures; sterna 3–5 with short, erect, relatively dense vestiture, but not velvety on sterna 5 and 6; genitalia (Figure 39) with gonostyle and cuspis broad, inner surface of each densely setose, digitus also broad and densely setose.

38. Hylomesa anomala, new species

FIGURE 40

This small species shares with H. ugandensis (Turner) the distinction of having the only females of the genus in which both the dorsum of the pronotum and of the first abdominal tergum lack a transverse anterior ridge. It differs from H. ugandensis in having the posterior fourth of the sixth tergum shagreened rather than polished, in having the mesopleural disk strongly produced in middle, and in having the anterior half of dorsal surface of pronotum coarsely and contiguously punctate in longitudinal rows.

The male of H. anomala lacks an anterior ridge on the pronotum but has a well-developed transverse ridge at base of disk of first abdominal tergum. It shares with H. dimidiaticornis (Bingham) the distinction of being the only Hylomesa male with specialized dense vestiture on any of the abdominal sterna. This is present on the fifth and sixth sterna in H. dimidiaticornis but on only the sixth in H. anomala.

The three males were captured while flying around a standing dead trunk in a wooded ravine through which a small stream flowed. The single female was taken while flying around a fallen dead trunk in a similar area about a kilometer away.

Subfamily METHOCHINAE

This peculiar subfamily with highly modified, wingless, antlike females and slender, winged males is represented in Sri Lanka by Karlissa Krombein with a single species, typical Methocha Latreille with three species, and Methocha subgenus Dryinopsis Brues with four species. Most species are known at present only from Sri Lanka, but M. (M.) litoralis, new species, occurs also on the east coast of South India.

So far as known all species of Methocha parasitize the larvae of cicindelid beetles dwelling in perpendicular burrows in the ground. Adlerz (1903, 1905) was the first to observe that the female Methocha approaches the entrance to the tiger beetle burrow, allows the beetle larva to clasp its mandibles around the constricted part of her thorax, and then paralyzes the larva by stinging it in the neck. Subsequently, the larva is dragged to the bottom of the burrow, and the wasp deposits an egg on the venter of the abdomen. The wasp then plugs the cell and fills the top part of the burrow with soil.

The host of Karlissa is unknown, but almost certainly it is the larva of one of the arboreal cicindelids which dwell in cavities in twigs and branches. The single known female of Karlissa was crawling on the trunk of a tree nearly a meter above the ground; an adult flightless cicindelid, Tricondyla coriacea Chevrolat, was captured elsewhere on the same tree. Shelford (1905, 1907) described the larva and its burrow of Neocollyris emarginata (Dejean), another arboreal cicindelid from Java. He surmised that the adult female Neocollyris oviposited through the woody outer tissue of the coffee twig into the central pith. When the egg hatched, the young larva excavated a burrow in the pith with an opening to the outside through the woody tissue. The mouth of the burrow was countersunk, and Shelford opined that the lower surface of the Neocollyris head completely plugged the burrow with its mandibles protruding into the countersunk area. Several taxa of Neocollyris occur in Sri Lanka. If the burrows of all genera of arboreal cicindelids are of similar construction, this may account for the remarkable mandibular development of female Karlissa (cf. Figures 22, 25). The two teeth at the apex of each mandible could be applied to the anterior margin of the cicindelid head in such a way that the head could be pried upward, thus exposing the beetle's neck to the wasp's sting.

Most of the Methocha males were captured in Malaise traps and were observed very infrequently around foliage or on the ground. We noted males entering traps as early as 6 A.M. at China Bay, Trincomalee, and one was attracted to an ultra-violet light trap. Some males entered traps later on cooler, windier days. Females were found crawling on the ground, usually in the vicinity of tiger beetle burrows. We noted mating or attempted mating three times by M. litoralis in the intertidal zone at Pesalai beach between 9:30 A.M. and noon.

Females were active during the day in partially or wholly shaded areas, but activity was severely limited in sparsely vegetated areas subject to intense sunlight. An exception to this was where the ground was damp, as in the intertidal habitat of M. litoralis. One damana (small open, sparsely vegetated area) across the Moderagam Aru near Kokmotte Bungalow, Wilpattu National Park, was inhabited by a small population of M. (M.) heveli, new species. On 24 May 1976 we reached the damana at 7:40 A.M. and captured two females on the bare gound at 7:45 and 7:55 A.M.; the ground by then was apparently too hot for further activity. Late in the afternoon females were again active, and we collected four females between 5:20 and 6:20 P.M. On the next day we reached the damana at 6:30 A.M. and collected five females between 6:35 and 7:11 A.M. We may have collected all of the adult females by that time, for we found none active between 5:10 and 6:25 P.M. We set small Malaise traps among shrubbery on the periphery of the damana but did not collect any males.

We followed Methocha females for lengthy periods at several locations but were unable to obtain a great deal of information. Our most successful observations were made at Pannika Villu, Wilpattu National Park, on the sand near the edge of the large villu (pond) on 1 November 1977. At 8:15 A.M., P.B. Karunaratne noted a small female of M. (Dryinopsis) taprobane, new species (11177 A; my code number, signifying month, day, and year), struggling with a tiger beetle larva at the burrow entrance of the latter. It appeared that the tiger beetle had grasped the wasp which allowed itself to be pulled into the burrow. The wasp came out almost immediately. It then walked around the burrow vicinity for more than five minutes. It went into the burrow at 8:16 A.M. and finally emerged at 8:37 A.M. Then it began to take in a grain of sand at a time. After several such trips we captured the wasp and excavated the burrow. The diameter of the perpendicular burrow was 2 mm at the entrance, and it narrowed to 1 mm farther down. At a depth of 42 mm there was a narrow, lump of dry sand. The entire burrow length was 78 mm, and the beetle larva was at the bottom with its head upward. It had a small egg on the venter of the abdomen opposite the dorsal hump. The egg was covered with a few grains of dry sand. The sand in which the burrow was excavated was very damp immediately below the surface. We put the larva in a cell in damp sand in a pill box for rearing. The wasp larva matured and spun an ovoid cocoon of delicate silk 5.5 mm long. Sand grains and chitinous parts of the host larva adhered to the outer surface of the cocoon. The adult wasp escaped when it eclosed but was probably a female.

At Ekgal Aru Reservoir on 22 February 1977, P.B. Karunaratne observed another small female M. (D.) taprobane (22277 A) on the sunny hard-packed earth of the drive near the Wildlife Department Circuit Bungalow. The wasp was plugging the burrow of a cicindelid larva and had filled the burrow to within 2 mm of the surface when we captured it. The plug was 5 mm thick of compacted earth. The next 45 mm of the burrow was empty, then there was a soft compacted thin plug directly on top of the head of cicindelid larva. The larva was in a nearly vertical cell at the bottom at a depth of 55 mm. We could find no egg on the larva, and it could not have been dislodged, because the excavation was made very carefully. We placed the beetle larva in a tin ointment box in damp soil, but no parasite developed.

We made a few observations on a small number of M. (M.) ubiquita, new species, females at Thawalamtenne on 18 February 1977. This was a flat area at mile post 30 on the Kandy-Mahiyangana Road. The locality had very low vegetation consisting mostly of grasses and prostrate broader leaved plants with occasional shrubs. The Methocha could not have been a very effective parasite, judged from the relatively small number of females compared with the numerous cicindelid burrows. At 10:12 A.M., I watched a female M. ubiquita (21877 A) on a bare spot in the meadow. In a minute it came to a spot that may have marked the plugged burrow of a small cicindelid larva. She began to burrow vertically, removing small grains of soil or sand 1–2 mm from entrance. In three minutes the burrow went downward the length of her body. She continued to back out of the burrow, sometimes pushing the soil behind her with her hind legs, sometimes carrying a grain or two out in her mandibles. This excavation went on till 10:25 A.M. At 10:38 A.M., I probed the burrow with a grass stem to a depth of 3/4 inches, but there was no reaction. We dug the burrow at 10:45 A.M. and found the Methocha about an inch below the surface with a plug of soil above her, and she was still digging. We did not find a beetle larva when we excavated deeper.

P.B. Karunaratne followed another M. ubiquita female (21877 B) for an hour-and-a-quarter. At about 10:45 A.M. she entered a large cicindelid burrow but was scared off by the larva in about half a minute. We dug up the burrow and found the beetle larva at a depth of 10 cm in rather heavy loam soil. There was no wasp egg on it.

At 1 P.M., D.W. Balasooriya found another M. ubiquita female (21877 C) digging as recorded above for 21877 A. She abandoned the burrow in a few minutes and started searching elsewhere. The burrow was only 2.5 cm long, and there was no sign of a beetle larva. This digging activity by 21877 A and C is certainly very puzzling, for there was no sign of a beetle larva in either case.

Several of the M. ubiquita females captured at Thawalamtenne had lost part of or all of their antennae. Quite likely these may have been amputated by a cicindelid larva when the Methocha probed the burrow.

Specific hosts are unknown for any of the Ceylonese Methochinae, but it is most unlikely that any of them are host specific. I believe that methochine females are highly opportunistic and will prey successfully upon any species of ground-dwelling or arboreal tiger beetle, provided that the host larva is neither too small nor too large. During my field work we collected Cicindelidae at every locality where they occurred. This enables me to suggest putative hosts for Ceylonese Methochinae as follows:

M. (M.) litoralis, new species—Cicindela biramosa Fabricius, C. distinguenda Dejean, C. sumatrensis Herbst

M. (M.) heveli, new species—Cicindela cancellata Dejean, C. ceylonensis ceylonensis W. Horn, C. c. diversa W. Horn, C. haemorrhoidalis Wiedemann, C. sexpunctata Fabricius, C. sumatrensis

Key to Ceylonese Species of Methochinae

39. Methocha (Methocha) litoralis, new species

FIGURES 32, 35

This distinctive species is known from two males and a long series of females taken at a single locality on the northwest coast of Sri Lanka on a narrow spit of land leading to Adams Bridge, the chain of small islets separating Sri Lanka and India. All Ceylonese specimens were taken in the intertidal zone of a sandy beach among stranded seaweed. The species is also known from a single female from Karikal, South India, a small city on the east coast 200 km north of the type-locality. Putative host larvae belonging to three taxa of Cicindelidae are listed in the discussion under “Subfamily Methochinae.”

Both sexes are distinguished from the other Ceylonese species of the typical subgenus by the much sparser and more delicate punctation; the male also has a more massive mandible and broader malar space, and the female has a pair of strong, acute mesosternal tubercles before the mid coxae instead of a pair of low obtuse teeth or transverse ridges.

ETYMOLOGY.—The specific name is from the Latin litoralis (of the seashore), an allusion to this restricted habitat.

PARATYPES.—4art, same data as holotype, 1 taken in copula with holotype and bearing code 12378 A (USNM); 1art, 14art, same data as allotype (USNM); 1art, 1art, same locality as holotype but 9 Apr 1981, in copula, K.V. Krombein (USNM). SOUTH INDIA. 1art, Karikal, 1 Jun 1932, P.S. Nathan (London). A pair of paratypes has been deposited in the National Museums of Sri Lanka (Colombo), and a female paratype has been placed in the British Museum (Natural History) and in Oxford University.

Female paratypes are 4.2 to 6.7 mm long, agree very well with the allotype in coloration, the punctation and sculpture is weaker in the smallest specimens, and the head width is 1.6–1.7 times the least interocular distance.

40. Methocha (Methocha) heveli, new species

FIGURES 31, 34

This species is known from both sexes from several localities in the Dry Zone. So far as known, it does not occur also in India, but there is a dearth of specimens from that country, so it may be collected eventually. Putative host larvae include some six taxa of Cicindelidae as listed in the discussion under the subfamily heading.

Methocha heveli is intermediate between M. litoralis, new species, and M. ubiquita, new species, in the comparative density of punctation. The genitalia and the blunt clypeal process with beveled apex distinguish the male from its congeners. The female has the apical mesosternal processes developed as blunt teeth or transverse ridges as in M. ubiquita, rather than acute teeth as in M. litoralis; it differs from M. ubiquita in the comparatively wider front, which is more strongly protuberant above the antennae and has several impunctate interspaces wider than the anterior ocellus.

ETYMOLOGY.—It is named for Gary F. Hevel, one of the Smithsonian Insect Project team leaders, who found the only two males in a Malaise trap.

Female paratypes range from 3.5 to 7.3 mm in length, are similar in coloration to the allotype, smaller specimens are more sparsely punctate and more delicately sculptured, and the posterior mesosternal teeth are occasionally reduced to transverse ridges.

41. Methocha (Methocha) ubiquita, new species

FIGURES 7, 8, 15–17, 30, 33

This is the most widely distributed species of typical Methocha in Sri Lanka, where it occurs in both the Dry Zone and Wet Zone and at altitudes up to some 2000 ft. It is not known to occur in India, but intensive collecting in South India may demonstrate its presence there. Putative host larvae include some 13 taxa of Cicindelidae as listed in the discussion under “Subfamily Methochinae.”

The male is the most densely punctate of the species of typical Methocha and has a distinctive beaklike clypeal process. The female also is the most densely punctate of that sex, has dark vestiture on the thoracic dorsum instead of white to cinereous, and has a comparatively narrower front.

ETYMOLOGY.—Its specific name is derived from the Latin ubique (everywhere), in allusion to its wide distribution in Sri Lanka.

A pair of paratypes has been placed in the National Museums of Sri Lanka (Colombo) and British Museum (Natural History). A male from Northern Province, Jaffna Dist., Elephant Pass, 2 Jan 23, G.M. Henry (Colombo) is not included in the type series because it lacks an abdomen.

Male paratypes are 4.5–10.8 mm long. In some specimens the normally dark parts of tibiae may be light brown. The clypeal process is occasionally heavier, and the median ridge on propodeum may be lacking dorsally, posteriorly, or both. The smallest specimens are comparatively more delicately sculptured and more sparsely punctate. Female paratypes are 4.0–6.0 mm long, and the coloration is rather uniform except that the propodeum rarely is brownish and there may be a reduced amount of red on the abdomen. Punctation and sculpture are also variable, smaller specimens being comparatively more sparsely punctate and with more delicate sculpture, and the largest specimen from Padaviya having subcontiguous punctures on front, pronotum, and scutum. Three specimens (Gilimale, Padaviya, Thawalamtenne) have the mesopleural rugulae finer and closer than in the rest of the series.

42. Methocha (Dryinopsis) taprobane, new species

FIGURES 18–20, 28, 38

This rather widely distributed species is the most common species of the subgenus Dryinopsis.

It occurs in both the Dry Zone and the Wet Zone but only in areas of moderate rainfall in the latter zone and at altitudes ranging near sea level to 2100 ft. Putative host larvae include some 13 taxa of Cicindelidae as listed in the discussion under the subfamily heading. This section also includes notes on the behavior of two females of M. (D.) taprobane and the larvae which they parasitized.

The male has light-red legs and small, relatively dense punctation on the mesopleuron; however, three of the 11 males have the mesopleuron more sparsely punctate, approaching the condition in M. (D.) anomala, new species, which also has light-red legs. Males of these two Dryinopsis may be separated by the genitalia (of. Figures 37, 38), by the ratio of ocellocular to postocellar distance (1.5 and 2.5 respectively), and by the lack of shagreening on the lateral area of dorsal surface of the propodeum in the present species.

Females of Dryinopsis are much more uncommon than those of typical Methocha. I am unable to distinguish significant differences among the seven available females in color, vestiture, punctation, and body proportions, and I believe that they are conspecific. The females are from five localities; males were collected at three of these (Ma Villu, Parayanalankulam, Pannika Villu), no males whatever at a fourth (Pooneryn), and one male of M. (D.) anomala at the fifth (Ekgal Aru); however, at the latter locality the two females were taken near the Circuit Bungalow, whereas the single male was collected a mile distant in the Sanctuary Jungle. The occurrence of two species at Ekgal Aru is of no significance, for all four species of male Dryinopsis have been collected in Udawattakele Sanctuary, Kandy. Females of M. taprobane and M. ceylonica, new species, are readily separated by the characters in the preceding key.

ETYMOLOGY.—The specific name is the Roman name for ancient Lanka.

MALE paratypes are 5.5–7.8 mm long and agree well in coloration with the holotype except that the femora are brownish in one specimen. There is some variation in density of punctation which is particularly noticeable on the mesopleuron. In a few specimens many of the discal punctures are separated by three or four times the diameter of a puncture, and in a few specimens these punctures are a bit larger, and many are separated by the diameter of a puncture.

FEMALE paratypes are 3.5–4.6 mm long and are similar in coloration to the allotype, except in several specimens the outer surface of the legs is darker brown as is the lower half of clypeal lobe. The head width is 2.2–2.4 times as wide as narrowest part of front, and the interocular distance at posterior ocelli is 1.5–1.6 times the least interocular distance.

43. Methocha (Dryinopsis) kandyensis, new species

FIGURE 29

This species of the Hill Country, known only from two males from Kandy and nearby Peradeniya, is the most easily recognized of the Ceylonese Dryinopsis males. The coloration of the legs is unique in that the basal fourth of mid and hind tibiae, and tarsi except apical segment, are testaceous as in Methocha (M.) ubiquita, new species, rather than having legs mostly light red as in M. (D.) taprobane, new species, and M. (D.) anomala, new species, or mostly black or dark brown as in M. (D) ceylonica, new species. Surprisingly, the genitalia are so similar to those of M. (D.) taprobane that the two species cannot be discriminated on that basis. Putative host larvae include some seven taxa of Cicindelidae as noted in the discussion under “Subfamily Methochinae.”

ETYMOLOGY.—The specific name is based on Kandy, capital of the last native kingdom.

HOLOTYPE.—art, Sri Lanka, Central Province, Kandy District, Peradeniya Botanical Garden, Jan 1971, Piyadasa and Somapala (USNM Type 100288).

MALE.—Length 7.3 mm, forewing 5.2 mm. Black, the following testaceous: palpi, middle third of mandible, narrow hind margin of pronotum, tegula, basal fourth of mid and hind tibiae, and all tarsi except apical segment; tip of mandible light red. Vestiture glittering white, relatively dense, short and suberect on head and thorax, sparser and subappressed on abdomen. Wings clear, stigma dark brown, veins lighter brown.

Head (Figure 29, drawn from paratype) width 1.3 times height from apex of clypeus to posterior ocellus, interocular distance at anterior ocellus 1.2 times least interocular distance; malar space evanescent; clypeal process broader than in M. (D.) taprobane, in profile blunter, heavier, not beaklike; ocellocular line 1.1 times postocellar line; second and third flagellar segments subequal in length and 1.2 times as long as first.

Pronotal disk without a strong anterior ridge, this area with a few fine transverse carinae behind which are fine punctures separated by the diameter of a puncture; scutum with small punctures, on median third anteriorly separated by half the width of a puncture, laterad of this and to parapsidal furrow the punctures confluent in transverse rows, area laterad of parapsidal furrow as on median section; scutellar disk with small punctures separated by half the diameter of a puncture, declivous lateral areas with smaller confluent punctures; mesopleuron with continuous crenulate groove above and anteriorly, disk with punctures slightly larger than in M. (D.) taprobane, mostly separated by 1 to 2 times the diameter of a puncture; propodeum without a median ridge, dorsal surface rounding gradually into posterior, dorsal surface with several median longitudinal rugulae, area laterad of these with small rugulose reticulations, posteriorly with larger rugulose reticulations, posterior surface finely and irregularly rugulose, lateral surface with a few coarse oblique rugulae on anterior half and very fine rugulose reticulations on posterior half.

Abdominal dorsum with fine punctures separated by one-and-a-half times to twice the diameter of a puncture; genitalia indistinguishable from those of M. (D.) taprobane (Figure 38).

FEMALE.—Unknown.

PARATYPE.—1art, same data as holotype but Kandy, Udawattakele Sanctuary, 1800 ft, in Malaise trap, 13–14 Aug 1973, G. Ekis et al. (USNM). The paratype is deposited in the National Museums of Sri Lanka (Colombo).

It is 8.1 mm long and is very similar in all details to the holotype except that there are two relatively strong transverse rugulae separating the dorsal and posterior surfaces of the propodeum.

44. Methocha (Dryinopsis) ceylonica, new species

FIGURE 37

This species, known only from two localities, is known from four males and one female. It occurs at Trincomalee in the Dry Zone and at Kandy in the Wet Zone with moderate rainfall, so we may expect it to have a relatively wide distribution in the country. Like M. (D.) kandyensis, new species, the male is very readily recognized by the coloration of the legs which are almost entirely dark in this species. The genitalia are indistinguishable from those of M. (D.) anomala, new species, which has almost entirely light-red legs. The comparatively greater postocellar distance and greater length of the third flagellar segment as compared to the first also distinguish this species from M. (D.) taprobane, new species, and M. (D.) kandyensis.

The sex association in M. ceylonica is based on having collected a male in a Malaise trap, 22 Sep 1980, on the topmost ridge in Udawattakele Sanctuary and the capture of a female on the ground, 14 Oct 1980, just a few meters from where the Malaise trap had been set. The dark brown tarsi of both sexes also suggest that this association is correct. The female is easily separated from that of M. taprobane by the characters cited in the foregoing key.

Putative host larvae include some eight taxa of Cicindelidae as listed in the discussion under “Subfamily Methochinae.”

ETYMOLOGY.—The specific name is based on one of the former names for its homeland.

(D.) kandyensis, in profile beaklike but stouter than in M. (D.) taprobane; punctation of front as figured for those 2 species; ocellocular line 2.1 times the postocellar line; third flagellar segment 1.1 times as long as second, 1.6 times as long as first.

Pronotal disk without an anterior ridge, this area with a few transverse carinae behind which are fine punctures mostly separated by the diameter of a puncture; scutum with small punctures, anteriorly on middle of disk separated by half the diameter of a puncture, laterad of this to parapsidal furrows with closer punctures, some of which are confluent transversely, area laterad of parapsidal furrow with more separated punctures; scutellar disk with small punctures separated by half the diameter of a puncture, declivous lateral areas with smaller confluent punctures; mesopleuron with continuous crenulate groove anteriorly and above, surface of disk with small punctures mostly separated by half the diameter of a puncture; propodeum without a median ridge, dorsal surface rounding gradually into posterior, the juncture without transverse rugulae, middle of dorsal surface with a few radiating rugulae, laterad of these the surface shagreened and with small rugulose reticulations, posterior surface with small rugulose reticulations becoming weaker toward apex, lateral surface with close oblique rugulae on basal half, posterior half with fine rugulose reticulations arranged in oblique rows.

Abdominal dorsum with fine puncture; separated by one-and-a-half times to twice the diameter of a puncture; genitalia (Figure 37).

ALLOTYPE.—art, same locality as holotype, but 14 Oct 1980, K.V. Krombein (USNM).

FEMALE.—Length 5.0 mm. Black, glossy; mandible red near tip; palpi testaceous; apical half of flagellum and tarsi dark brown; sixth tergum and fifth and sixth sterna chestnut. Vestiture sparse, erect and black on top of head, thoracic dorsum and first 2 terga, silvery and suberect on face and third through fifth terga, the setae on those terga directed posteriorly.

Balasooriya, V. Gunawardane (USNM). One paratype has been deposited in the National Museums of Sri Lanka (Colombo).

The paratypes are 8.0–8.4 mm long and are very much like the holotype except that the tarsi are lighter brown in two specimens.

45. Methocha (Dryinopsis) anomala, new species

This species and M. (D.) ceylonica, new species, differ from the other two Ceylonese males of the subgenus in having the ocelli closer together so that the ocellocular distance is twice or more the postocellar distance instead of being 1.5 times or less. These two species also differ in having the lateral area of the dorsal propodeal surface strongly shagreened and in having the cuspis of the genitalia digitate rather than blunt (cf. Figures 37, 38). The almost entirely light-red legs of M. (D.) anomala separate it at once from M. (D.) ceylonica which has almost entirely dark-brown legs.

Methocha anomala occurs in both the Dry Zone and Wet Zone, in areas ranging from light to heavy rainfall. Putative host larvae include some eight taxa of Cicindelidae as noted in the discussion under “Subfamily Methochinae.”

ETYMOLOGY.—The specific name is based on the Greek anomalos (strange).

HOLOTYPE.—art, Sri Lanka, Eastern Province, Amparai District, Ekgal Aru Sanctuary Jungle, 100 m, in Malaise trap, 19–22 Feb 1977, K.V. Krombein, P.B. Karunaratne, P. Fernando, D.W. Balasooriya (USNM Type 100290).

Vestiture glittering white, relatively dense, short and suberect on head and thorax, sparser and subappressed on abdomen. Wings clear, stigma dark brown, veins light brown.

Head width 1.4 times height from apex of clypeus to fore ocellus, interocular distance at anterior ocellus 1.3 times the least interocular distance; malar space evanescent; clypeal process narrow, in profile beaklike; punctation of front as in M. taprobane, new species (Figure 28), ocellocular line 2.5 times postocellar line; second and third flagellar segments subequal, 1.5 times as long as first.

Pronotal disk without anterior ridge, this area with a few transverse carinae behind which are fine punctures mostly separated by diameter of a puncture; scutum with small punctures, on raised median area these separated by half the diameter of a puncture, laterally and posteriorly the punctures subcontiguous except narrow areas laterad of parapsidal furrow with sparser finer punctures; scutellar disk with small punctures separated by half the diameter of a puncture, declivous lateral areas with smaller confluent punctures; mesopleuron with continuous crenulate groove above and anteriorly, disk with fine punctures mostly separated by 2 to 3 times the diameter of a puncture; propodeum without median ridge, dorsal and posterior surfaces rounding gradually into each other and not separated by transverse rugulae, central area with coarse, irregular rugulose reticulations, lateral area strongly shagreened and with fine rugulose reticulations laterally and posteriorly, posterior surface with small rugulose reticulations becoming weaker toward apex, lateral surface with close oblique rugulae on anterior half, and fine rugulose reticulations tending to be in oblique rows on posterior half.

Wickwar (London), is not included in the type series because it lacks a head.

The male paratypes are 8.0–8.5 mm long and agree well in all details except that the tarsi of the Udawattakele and Kanneliya specimens are brown.

Genus Karlissa Krombein

Karlissa Krombein, 1979:428 [type-species: Methoca [sic] rugosa Cameron, by original designation].

The species on which this unusual genus is based has been known for more than eight decades only from the unique male type of M. rugosa Cameron from Ceylon. I recognized that it constituted a new genus of Methochinae when I studied the type in 1965. In proposing the genus Karlissa, I suggested that its rarity might be due to its leading an arboreal existence and that it might parasitize larvae of arboreal tiger beetles dwelling in borings in twigs and branches.

I searched unsuccessfully in Sri Lanka for Karlissa during 11 trips from 1969 to 1980. Finally, on my twelfth trip in 1981, a serendipitous event occurred leading to the capture of the second male. I had been collecting small Hymenoptera and Coleoptera in leaf litter on the downslope of the bund at Palatupana tank. This is on the xeric southeast coast of the Dry Zone and is a locality where I had collected during eight previous trips. At 0915 bladder pressure from a diuretic caused me to move 10 meters away beneath a ranawara tree. Just as I completed this urgent elimination, I noted a male Karlissa clinging to a low plant. Several minutes earlier or later and I might have missed it. Two days later we captured the first known female Karlissa crawling on a trunk of an adjacent ranawara, as well as an adult flightless cicindelid, Tricondyla coriacea Chevrolat, its putative host.

A generic diagnosis of the male was published in 1979, and the following diagnosis is presented for the female.

FEMALE.—Head (Figures 24, 25): maxillary palpus 6-segmented, labial palpus 4-segmented; mandible stout, concave on inner surface, apex with 2 equal teeth (Figure 25b); apical margin of clypeus deeply and narrowly emarginate between median lobe and the greatly produced lateral lobes; apex of labrum with a narrow lateral process extending beyond margin of median clypeal lobe; front with a pair of acute tubercles above antennal insertions; ocelli in an equilateral triangle; antenna as in Methocha subgenus Methocha.

Thorax (Figure 26): scutum, scutellum, and mesopleuron completely fused, sutures absent that separate these sclerites in Methocha subgenus Methocha; mesosternum with a small median fovea but without median carina, margined posteriorly by a weak carina before mid coxae; tibial calcaria 1–1–1; outer surface of mid and hind tibiae with a single preapical spine.

Abdomen as in Methocha.

46. Karlissa rugosa (Cameron)

FIGURES 24–27, 36

Methocha rugosa Cameron.—Krombein, 1968:3 [confirmed as Methochinae].

Karlissa rugosa (Cameron).—Krombein, 1979:431–433, figs. 1, 2.

This rare species was known only from the unique holotype male until I captured a pair in the Dry Zone in 1981. The type bears two labels, a small square with a pencilled “11” probably referring to the figure accompanying the description and Cameron's label “Methoca/rugosa/Cam. Type.” Cameron cited no collector and stated in his original decription that the specimen came from Ceylon. His 1897 paper described a number of new Hymenoptera mostly from India, but it included 22 species from Ceylon. Ten of these were cited as being from Trincomali (Yerbury), six as Ceylon (Yerbury), and five as Ceylon (Rothney); the sixteenth, M. rugosa, presumably was collected by either Yerbury or Rothney.

My male was a teneral specimen clinging to a plant beneath a ranawara tree (Cassia auriculata Linnaeus, Leguminosae). It fell to the ground and I picked it up. If my theory is correct that Karlissa preys upon larvae of arboreal flightless cicindelids breeding in borings in twigs or branches, then this male presumably fell onto the plant from a branch overhead. We found the female two days later crawling downward on a trunk of another ranawara about a meter above the ground and a few meters from where the male had been captured. Earlier on this latter date I collected an adult flightless cicindelid, Tricondyla coriacea Chevrolat, on the same tree; it is the putative host of Karlissa.

The holotype is in reasonably good condition except that most of the flagellar segments are missing (note Cameron's figure) as well as the terminal segment of left foretarsus, left mid and hind tibiae and tarsi, and the right foretarsus except for the basal segment. Some vestiture, especially upon eyes, has been abraded, probably the result of the specimen having been preserved in formalin or some other liquid preservative when collected.

MALE.—Length 11–15 mm, forewing 8–9 mm. Black, glossy; mandible, scape, fore trochanter, femur and tibia darker red than palpi, antennal pedicel and first 4 flagellar segments which are lighter red; fifth flagellar segment infuscated at apex above; apex of pronotum narrowly reddened in type as are outer and hind margins of tegula in both specimens. Forewing hyaline to basal vein, the apical half infuscate; apical third of hind wing infuscate.

REQUIREMENTS FOR SMITHSONIAN SERIES PUBLICATION

Manuscripts intended for series publication receive substantive review within their originating Smithsonian museums or offices and are submitted to the Smithsonian Institution Press with approval of the appropriate museum authority on Form SI–36. Requests for special treatment—use of color, foldouts, casebound covers, etc.—require, on the same form, the added approval of designated committees or museum directors.

Review of manuscripts and art by the Press for requirements of series format and style, completeness and clarity of copy, and arrangement of all material, as outlined below, will govern, within the judgment of the Press, acceptance or rejection of the manuscripts and art.

Copy must be typewritten, double-spaced, on one side of standard white bond paper, with 1¼″ margins, submitted as ribbon copy (not carbon or xerox), in loose sheets (not stapled or bound), and accompanied by original art. Minimum acceptable length is 30 pages.

Front matter (preceding the text) should include: title page with only title and author and no other information, abstract page with author/title/series/etc., following the established format, table of contents with indents reflecting the heads and structure of the paper.

First page of text should carry the title and author at the top of the page and an unnumbered footnote at the bottom consisting of author's name and professional mailing address.

Center heads of whatever level should be typed with initial caps of major words, with extra space above and below the head, but with no other preparation (such as all caps or underline). Run-in paragraph heads should use period/dashes or colons as necessary.

Tabulations within text (lists of data, often in parallel columns) can be typed on the text page where they occur, but they should not contain rules or formal, numbered table heads.

Formal tables (numbered, with table heads, boxheads, stubs, rules) should be submitted as camera copy, but the author must contact the series section of the Press for editorial attention and preparation assistance before final typing of this matter.

Taxonomic keys in natural history papers should use the alined-couplet form in the zoology and paleobiology series and the multi-level indent form in the botany series. If cross-referencing is required between key and text, do not include page references within the key, but number the keyed-out taxa with their corresponding heads in the text.

Synonymy in the zoology and paleobiology series must use the short form (taxon, author, year:page), with a full reference at the end of the paper under “Literature Cited.” For the botany series, the long form (taxon, author, abbreviated journal or book title, volume, page, year, with no reference in the “Literature Cited”) is optional.

Footnotes, when few in number, whether annotative or bibliographic, should be typed at the bottom of the text page on which the reference occurs. Extensive notes must appear at the end of the text in a notes section. If bibliographic footnotes are required, use the short form (author/brief title/page) with the full reference in the bibliography.

Text-reference system (author/year/page within the text, with the full reference in a “Literature Cited” at the end of the text) must be used in place of bibliographic footnotes in all scientific series and is strongly recommended in the history and technology series: “(Jones, 1910:122)” or “…Jones (1910:122).”

Bibliography, depending upon use, is termed “References,” “Selected References,” or “Literature Cited.” Spell out book, journal, and article titles, using initial caps in all major words. For capitalization of titles in foreign languages, follow the national practice of each language. Underline (for italics) book and journal titles. Use the colon-parentheses system for volume/number/page citations: “10(2):5–9.” For alinement and arrangement of elements, follow the format of the series for which the manuscript is intended.

Legends for illustrations must not be attached to the art nor included within the text but must be submitted at the end of the manuscript—with as many legends typed, double spaced, to a page as convenient.

Illustrations must not be included within the manuscript but must be submitted separately as original art (not copies). All illustrations (photographs, line drawings, maps, etc.) can be intermixed throughout the printed text. They should be termed Figures and should be numbered consecutively. If several “figures” are treated as components of a single larger figure, they should be designated by lowercase italic letters (underlined in copy) on the illustration, in the legend, and in text references: “Figure 9b.” If illustrations are intended to be printed separately on coated stock following the text, they should be termed Plates and any components should be lettered as in figures: “Plate 9b.” Keys to any symbols within an illustration should appear on the art and not in the legend.

A few points of style: (1) Do not use periods after such abbreviations as “mm, ft, yds, USNM, NNE, AM, BC.” (2) Use hyphens in spelled-out fractions: “two-thirds.” (3) Spell out numbers “one” through “nine” in expository text, but use numerals in all other cases if possible. (4) Use the metric system of measurement, where possible, instead of the English system. (5) Use the decimal system, where possible, in place of fractions. (6) Use day/month/year sequence for dates: “9 April 1976.” (7) For months in tabular listings or data sections, use three-letter abbreviations with no periods: “Jan, Mar, Jun,” etc.

Arrange and paginate sequentially EVERY sheet of manuscript—including ALL front matter and ALL legends, etc., at the back of the text—in the following order: (1) title page, (2) abstract, (3) table of contents, (4) foreword and/or preface, (5) text, (6) appendixes, (7) notes, (8) glossary, (9) bibliography, (10) index, (11) legends.
