SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION

The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Institution, Joseph Henry articulated 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 not strictly professional.” This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series:

Smithsonian Annals of Flight

Smithsonian Contributions to Anthropology

Smithsonian Contributions to Astrophysics

Smithsonian Contributions to Botany

Smithsonian Contributions to the Earth Sciences

Smithsonian Contributions to Paleobiology

Smithsonian Contributions to Zoology

Smithsonian Studies in History and Technology

In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of professional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. Each publication is distributed by mailing lists to libraries, laboratories, institutes, and interested specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available.

Introduction

The genus Peleopoda as herein defined consists of thirteen species which have been previously associated with at least five genera in a number of different families including the Gelechiidae, Xyloryctidae, Stenomidae, and Oecophoridae. One species in the present study is described as new. This report presents the first review of this genus for the Nearctic and Neotropical Regions and includes all the species known to occur in these areas. Previous studies on species and genera included here have been brief, largely lacking in illustrations or keys, and primarily devoted to the description of new taxa.

Undoubtedly, the lack of more comprehensive studies on the part of previous workers has been due to the paucity of specimens. A similar lack of material was experienced during the course of the present study even though efforts to obtain specimens have been made by the author and many other people while conducting field studies in both the Nearctic and Neotropical Region. Due to these efforts a number of species are now represented by a much larger series over a more adequate portion of their geographical range. A large number, however, are still known from only one or two specimens and distribution data is inadequate for most of the species.

History

The genus Peleopoda was established by Zeller (1877) for a new species, lobitarsis, which he described from a single male from Panama. Busck (1908) described a new genus of Gelechiidae, Durrantia, for a Zeller species, piperatella, noting: “The type has veins 7 and 8 in the forewings stalked; I include as generic character ‘or coincident’ in order not to exclude another closely related and very similar, undescribed Texan species, which I believe congeneric, in spite of this single difference.” Walsingham (1912) added four additional species to Durrantia from Central and South America. In the same study he described a new genus of Gelechiidae, Theatria, with one included species, spudasma, which he related to another genus, failing to note that the venational characters were identical to those of the four species of Durrantia he had described on the preceding two pages.

Busck (1911) redescribed Peleopoda Zeller, noting that though Zeller’s generic description was totally inadequate for absolute determination he felt assured in applying the name to the genus before him and gave the characters accordingly. He included three new species from French Guiana on which he based his characterization of the genus.

Busck (1912) described yet another genus in the Gelechiidae, Dolidiria, for a single new species, arcanella, noting: “The genus is nearest to and a direct development from Durrantia Busck, differing only in veins 7 and 8 of the forewings being coincident instead of stalked.”

Meyrick (1916) described a new genus of Oecophoridae with the following comment: “… Mr. Busck has regarded this genus as identical with Peleopoda Zell., with which conclusion I do not agree; Zeller’s type species is indeed unknown to both of us, but the accuracy and reliability of Zeller’s work entitles us to read his description literally; …; the characters as given point to a genus allied to Cryptolechia and quite distant from the present, and the superficial appearance as shown by the figure confirms this.” Meyrick (1922) in his review of the Oecophoridae lists Peleopoda Zeller with one included species, lobitarsis, and indicated that he had not studied material of this genus and species and that the characters in the original description were incomplete and doubtful. In 1925 Meyrick described a new species of Durrantia from Peru and noted: “Dolidiria Busck is a synonym of Durrantia; the genus belongs to the Xyloryctid group, and is closely allied to Odites.” On the same page Meyrick gives a revised description of the genus Peleopoda Zeller and comments as follows: “Having obtained a fine example of the type-species, P. lobitarsis, from Jurimaguas, Peru, I find that my conjectural reference of it to the Oecophoridae was mistaken, and it is really nearly related to Durrantia, and also to Xylorycta.”

Meyrick (1930) described the second species assigned to Peleopoda, semocrossa, from Bolivia and indicated that it was closely related and similar to lobitarsis. Busck (1934) listed Peleopoda and the two described species in the Stenomidae part of the “Lepidopterorum Catalogus” series. Gaede (1939) listed Peleopoda in the Oecophoridae part of the same series and only included one species, Lobitarsis.

Clarke (1955) listed Durrantia in the Xyloryctidae and illustrated the wings and genitalia of the two Meyrick species in his study of the Meyrick types in the British Museum (Natural History).

Clarke (1956) described a new genus in the Oecophoridae, Pseuderotis, for a new species, Cannescens, from Argentina. Clarke (1963) listed Peleopoda in the Oecophoridae portion of his Meyrick Types study and illustrated the wings and genitalia of semocrossa.

Biology

DISTRIBUTION.—As pointed out previously the distributional data for Peleopoda are far from complete, but the Neotropical character of the genus is readily observable. The two species that occur in the Nearctic Region (piperatella, obiterella) have distributions which indicate only a fringe penetration at best. The large concentration of species in Central America could suggest that area as the center of origin for the group with subsequent dispersal both north and south, but primarily south.

It is very likely that the genus is more abundant in South America than present information indicates. Undoubtedly, further collecting will produce additional records of known species as well as new species.

LIFE HISTORY.—As is the case for a vast majority of Microlepidoptera in the Neotropics very little is known of the life histories of the species included here. Except for Bourquin’s (1957) casual account of his observations on P. cannescens there are no published studies of the biology of any Peleopoda species. Host plant data from specimens have been utilized wherever possible and host plants have been listed for four species including P. cannescens. From these data, species in the genus are now known to feed on plants in the families Malpighiaceae, Verbenaceae, Polygonaccae, and Platanaceae. In addition, there is one questionable record of P. resurgens on a species of Orchidaceae which is discussed in further detail under that species.

Classification

While engaged in studies on the related family Stenomidae, my attention was first directed to the group of moths included in this study. Several of the species and genera have been formally assigned to that family at one time or another and specimens are most usually found mixed with undetermined and unsorted stenomid material in collections. The primary reason for this is the possession by these species of a number of characters which have been distinctive for the Stenomidae, i.e., veins 6 and 7 of the hind wing stalked, absence of pecten on the basal segment of the antennae, and general shape of the wings. Examination of the genitalia, however, indicates a clear relationship with the family Oecophoridae and when studied carefully there are supportive characters to be found in the venation for this placement.

The presence of spines on the gnathos and the general shape and modification of the valvae in the male genitalia are frequently encountered in the Oecophoridae as is the long ovipositor in the female genitalia. These characters rarely occur in the Stenomidae. Although the stalking of veins 6 and 7 in the hind wing is typically a stenomid characteristic the stalking or coincidence of veins 7 and 8 in the forewing is oecophorid as well as the tendency of veins 3 and 4 in the hind wing to be approximate or stalked.

The question of proper placement of Peleopoda within the family Oecophoridae is a very difficult one. The family is in great need of study, particularly the Neotropical representatives. The existing higher classification is essentially that established by Meyrick (1922) in his world catalog for the family. Unfortunately, Meyrick did not include characters of the genitalia in his studies and the five categories into which he divided the family are virtually useless since they are based on very superficial characters of the antenna and termination point of vein 7 in the forewing. Thus, until further comprehensive studies are made, the relationships of the large number of genera in the family must remain uncertain.

There is a possibility that future studies on the Neotropical Oecophoridae will indicate that the species included here should be further divided into either genera or subgenera. There are several venation and genitalic characters which could be evaluated in this fashion. Without sufficient comparative information for other Neotropical genera, however, it seems more advisable to take a conservative approach for the time being.

TYPE SPECIES.—Peleopoda lobitarsis Zeller.

Head with loosely raised scales; antenna slightly serrulate in male, simple in female, basal segment without pecten but in most species a row of spreading scales at base; maxillary palpi developed, simple; labial palpus long, recurved, extending beyond vertex, second segment roughened beneath with appressed scales, apical segment smooth, only slightly shorter than second; tongue developed, scaled at base. Legs with hind tibia thickened with dense scales. Forewing with 12 veins, 11 with fusion of 7 and 8; 1b furcate; 2 arising well before angle; 3, 4, and 5 separate or approximate; 6 to termen below apex; 7 and 8 stalked or coincident, 11 from middle of cell or before. Hind wing with 8 veins, 7 with fusion of 3 and 4; 1b furcate at base; area between fork point of attachment for hair pencil; 2 remote; 3 and 4 connate, stalked or coincident; 5 connate, approximate or remote to 3+4; 6 and 7 stalked.

MALE GENITALIA.—Symmetrical or asymmetrical; uncus bifid; gnathal plate separate or divided, spiny; valvae with moderate to large lobes from costae frequently overlapping medially; anellus with or without lateral lobes; aedeagus with ductus ejaculatorius attached at base, cornuti present or absent.

FEMALE GENITALIA.—Ovipositor moderately long to long, telescoping; ostium bursae typically sclerotized, sometimes membranous, in some species extruded beyond body wall; ductus bursae typically membranous, in one species partially sclerotized; corpus bursae membranous, signa present or absent.

REMARKS.—This taxon can be easily separated from the other genera of Oecophoridae by stalking of veins 6 and 7 in the hind wing and the bifid uncus in the male genitalia. The lack of sufficient material makes the definition of the genus on female characters extremely difficult at this time. The principal character used by Zeller in establishing this genus, the elaborate dorsal scale tufts on the tibia and tarsi of the hind leg, although present to varying degrees, were found to be seldom as elaborate and distinctive in the species other than the type species, lobitarsis.

REMARKS.—The type specimen of this species has not been located during the course of the present study. In the original description Zeller indicated the type was in the Staudinger Museum, which now is located at the Zoologisches Museum, Museum Fur Naturkunde de Humboldt—Universitat zu Berlin. Attempts to locate the type in that collection have been unsuccessful to date. The description and illustrations provided here were derived from the only other known specimen. It is from the Meyrick collection now in the British Museum (Natural History).

REMARKS.—This large and striking species is known only by the type specimen from Colombia. It appears to be closely related to the following species, P. semocrossa, but is readily separated by the development of the apex of one valva into an upright, clublike structure. Since P. semocrossa is also known only by a single speimen it is not possible to adequately determine the relative positions of these two species at this time.

Peleopoda semocrossa Meyrick

Hind wing white; cilia white.

MALE GENITALIA (slide JFGC 5606, type).—Uncus bifid, moderate. Gnathal plate fused. Anellus a simple band, without lateral lobes. Valvae asymmetrical, one shorter, wide at base tapering to narrow rounded apex, the other near uniform width to two-thirds, then narrowing sharply to less than one-third.

REMARKS.—In the original description of this species Meyrick notes, “Closely related and similar to the typical lobitarsis, but differs in stalking of vein 9 with 7, and brown mark in cilia.” Both this and the preceding species show a relationship in the genitalia to P. lobitarsis; however, they are much closer to each other than either is to P. lobitarsis. The distinguishing characters between P. semocrossa and P. navigatrix have been given in the remarks concerning the latter species.

REMARKS.—This species is nearest to P. thamnolopha on characters of the genitalia but is easily separated by the simple valvae in the male and a sclerotized ostium bursae in the female. P. thamnolopha, on the other hand, has a well-developed costal process on the valva in the male and a large membranous ostium bursae in the female.

The rather involved nomenclatural activities associated with this species have been summarized by Busck (1908), and I will not reiterate them here except to point out that my study verifies Busck’s conclusions entirely.

TYPE.—In the Naturhistorisches Museum, Vienna, Austria.

TYPE LOCALITY.—La Trinidad, Costa Rica.

HOST PLANT.—Unknown.

DISTRIBUTION.—Guatemala: Volcan Santa Maria (November). Costa Rica: La Trinidad (no date).

REMARKS.—This species is closely related to P. obiterella (Busck), and the distinguishing characters have been discussed in the remarks pertaining to that species.

Meyrick originally described P. thamnolopha in the African genus Asapharcha (Xyloryctidae) on the basis of the wing venation. Examination of the type, a female, and the only other known specimen, a male in the NMNH, clearly indicates placement in the Oecophoridae. Future studies may indicate that P. thamnolopha and P. obiterella represent a separate genus. At the present time, however, it seems more appropriate to include them in Peleopoda.

Peleopoda cannescens (Clarke), new combination

FIGURES 22–25; PLATE 2A; MAP 3

Pseuderotis cannescens Clarke, 1956, p. 256.

Alar expanse, 17–18 mm.

Antenna white shaded with light brown basally, light brown beyond. Labial palpus white, second segment shaded with brown exteriorly, apical segment shaded with brown at tip. Head, thorax white shaded with brown. Forewing white to pale yellow; costa shaded with brown from midpoint to apex; a spot in the middle of cell, one at end of cell, two in the fold, dark brown; a terminal and subterminal series of transverse spots, brown; entire wing randomly sprinkled with brown scales; cilia white mixed with pure yellow.

FIGURES 22–25.—Peleopoda cannescens (Clarke): 22, wing venation; 23, ventral view of female genitalia; 24, lateral view of aedeagus; 25, caudal view of male genitalia (aedeagus removed).

TYPE.—In the National Museum of Natural History.

TYPE LOCALITY.—Tigre, Argentina.

HOST PLANT.—Polygonom persicariodes H.B.K. [Polygonaceae], Platanus orientalis L. [Platanaceae].

DISTRIBUTION.—Argentina: Tigre (no date). Brazil: Nova Teutonia, 300–500 m (May, August, September); Pelotas (October).

REMARKS.—This species is nearest P. arcanella in size and maculation, but examination of the genitalia indicates that, although there is an indication of relationship with the P. arcanella group, there are some striking differences. P. cannescens has the gnathos fused, the valvae symmetrical and the vesica of the aedeagus unarmed in the males, whereas the P. arcanella group has the gnathos separate, the valvae asymmetrical, and the vesica armed. The females of P. cannescens have the ostium bursae unextruded, the bursa copulatrix more than three times the length of the ovipositor, and a single, small signum in the corpus bursae. In females of the P. arcanella group the ostium bursae is extruded beyond the body wall, the bursa copulatrix short, never more than twice the length of the ovipositor, and the two signa in the corpus bursae.

The life history of the species has been briefly described by Bourquin (1957). The larva lives and pupates beneath a white silk web on the leaves of Polygonum persicariodes and Platnus orientalis. The web causes a slight folding of the leaf and the larva orients itself beneath the web either along the leaf midvein or the central axis of the nest. Departure from the nest when disturbed is accomplished through an exit hole in the leaf.

MAP 3.—Distribution of Peleopoda cannescens.

It is very likely that Platanus orientalis is a secondary host plant since it is an introduced ornamental tree in Argentina. The case of Polygonum persicariodes is more difficult to analyze. This plant is an extremely widespread weed of moist environments from Mexico to Argentina. It may represent another secondary host or the primary host. On the other hand, P cannescens may well be a general feeder and utilize a broad spectrum of plants as hosts.

Dolidiria arcanella Busck, 1912, p. 5.

Alar expanse, 13–21 mm.

Antenna white basally, shaded with golden brown beyond. Labial palpus white, second segment shaded with brown exteriorly. Head, thorax white. Legs ranging from white to brown, forelegs always darkest, hind legs always lightest. Forewing ground color white frequently suffused with very pale yellow; costa narrowly edged with light yellow to golden brown from base to apex; spot at end of cell and discal spot a patch of golden brown with black center; entire wing randomly sprinkled with black scales; cilia ranging from pure white to alternating bands of pale yellow and brown. Hind wing ranging from white to pale yellow; cilia ranging from white to pale yellow tending to be darkest at wing apex.

MALE GENITALIA (slide WDD 2939).—Uncus bifid, short. Gnathal plate fixed, spines divided medially into two patches. Anellus wedge-shaped, lateral lobes moderate. Valvae asymmetrical; one simple, approximately uniform in width throughout, somewhat concave; the other shorter, approximately uniform in width to midpoint, reduced sharply at midpoint forming a fingerlike apical half, a small, setiferous ampulla on costa near midpoint. Aedeagus long, slightly curved, only slightly wider basally, vesica armed with two cornuti, one long, needlelike, approximately half the length of aedeagus, the other short, thornlike.

FEMALE GENITALIA (slide WDD 3824).—Ostium bursae sclerotized, extruded beyond body wall. Ostium with ventromedial excavation causing the extruded portion of the ostium bursae to appear heart-shaped in ventral view. Ductus bursae short, broad, membranous.

FIGURES 26–29.—Peleopoda arcanella (Busck): 26, wing venation; 27, ventral view of female genitalia; 28, lateral view of aedeagus, 29, caudal view of male genitalia (aedeagus removed).

REMARKS.—Busk described a separate genus for this species on the basis of veins 7 and 8 of the forewing being coincident rather than stalked although he noted its relationship with other species included in the genus Durrantia (= Peleopoda). Examination of the genitalia clearly demonstrates the close relationship of P. arcanella to other species included here and indicates that the venation character is of specific significance only.

MAP 4.—Distribution of Peleopoda arcanella.

This species appears most closely related to P. amabilis, but has several distinguishing characters in the genitalia. In the male genitalia P. arcanello has a wedge-shaped anellus and one valva sharply narrowed beyond the midpoint, whereas in P. amabilis the anellus is rectangular and the valvae are much wider apically than basally. In the female genitalia the extruded portion of the ostium bursae is heart-shaped in P. arcanella and irregularly excavate in P. amabilis.

Peleopoda amabilis (Walsingham), new combination

FIGURES 30–37; PLATE 2C; MAP 5

Durrantia amabilis Walsingham, 1912, p. 115.

Alar expanse, 13–27 mm.

Antenna white basally, light brown beyond. Labial palpus white, second segment shaded from pale yellow to dark brown exteriorly. Head white to pale yellow. Thorax white shaded dorsally from pale yellow to dark brown. Legs white to pale yellow, tibia and tarsi frequently shaded with brown. Forewing white to pale yellow, costa, apex, termen, dorsum varyingly edged with yellow to brown; in some specimens a few darker scales at end of cell, and a few randomly sprinkled over wing; cilia white to pale yellow, darker at wing apex. Hind wing white; Cilia white, slightly darker at apex.

MALE GENITALIA (JFGC 11197).—Uncus bifid, short. Gnathal plate divided. Anellus rectangular; lateral lobes asymmetrical, one approximately twice as long as the other. Valvae asymmetrical, both expanded apically with the apical width at least twice that of width at midpoint; one valva with apically directed saccular process. Aedeagus slightly bent, tapering from base to apex; vesica armed with a single, long, slightly sinuate cornutus which slightly exceeds the length of aedeagus.

FEMALE GENITALIA (JFGC 11179).—Ostium bursae long, sclerotized, extruded beyond body wall. Ostium with ventral edge deeply excavated. Ductus bursae short, membranous, convoluted. Corpus bursae membranous, signa consisting of two sclerotized plates with invaginated median keels.

TYPE.—In the British Museum (Natural History).

TYPE LOCALITY.—Volcan de Atitlan, Guatemala, 2,500–3,500 ft.

HOST PLANT.—Lantana camara L. [Verbenaceae].

DISTRIBUTION.—Mexico: Cuernavaca, Morelos (June); Tamazunchale (June); 25 m N. Tamazunchale, S.L.P., 400 ft. (August); Cordoba, Ver. (July, September). Guatemala: Volcan de Atitlan, 2,500–3,500 ft. (no date); Chejel (no date); Volcan Station Maria (July). Venezuela: Aroa (no date).

REMARKS.—This species is extremely variable in both size and degree of maculation. In general, the larger specimens are readily recognized on the basis of their size; the smaller specimens, however, are frequently difficult to separate from closely related species such as P. pugnax on superficial characters such as maculation. Examination of the genitalia readily reveals characters distinctive for this species. In the male the shape and armature of the valvae and the single long sinuate cornutus in the aedeagus serve to distinguish P. amabilis from all other species in the genus. In the female the shape of the ventral edge of the ostium and the long, sclerotized ostium bursae readily separate the species from all others.

MAP 5.—Distribution of Peleopoda amabilis.

The host plant recorded for this species is based on one reared specimen in the USNM collection from Tamazunchale, Mexico. If P. amabilis occurs through the range of L. camara its distribution will be far wider than reported here. Lantana camara is widely distributed in tropical America and due to its ornamental value has been naturalized in the Old World. In some areas, such as Hawaii, it has become a troublesome weed.

Peleopoda resurgens (Walsingham), new combination

FIGURES 38–41; PLATE 2D; MAP 6

Durrantia resurgens Walsingham, 1912, p. 115.

Alar expanse, 20–22 mm.

Antenna white basally, light brown beyond. Labial palpus white, second segment shaded with brown exteriorly. Head, thorax white. Legs white, forelegs heavily shaded with brown exteriorly, mid and hind-legs lightly shaded with brown. Forewing white to pale yellow; three brown spots, one at middle of cell, one at end of cell and one in the fold; a series of elongate brown marks along termen from apex to tornus, entire wing randomly sprinkled with brown scales; cilia pale yellow. Hindwing and cilia pale yellow.

Male genitalia (JFGC 11177). Uncus bifid, moderate. Gnathal plate partially divided, spines divided into two patches. Anellus U-shaped. Valvae symmetrical, of approximately uniform width throughout, a costal lobe at apical two-thirds, a saccular process at basal one-third. Aedeagus short, bent, tapering from base to apex; vesica armed with two cornuti; one short, thornlike, one long, sinuate, extending three-fourths the length of aedeagus, spatulate at apex.

Female genitalia (WDD 3923, type). Ostium bursae long, sclerotized, extruded beyond body wall. Ostium with ventral edge slightly excavate, dorsal edge pointed with one side broadly and irregularly serrate, with broad, sclerotized flange encircling three-fourths of the extruded portion. Ductus bursae short, membranous. Corpus bursae membranous, signa consisting of two sclerotized plates with invaginated median keels.

TYPE.—In the British Museum (Natural History).

TYPE LOCALITY.—Volcan de Atitlan, Guatemala, 2,500–3,500 ft.

HOST PLANT.—Laelia sp.? [Orchidaceae].

DISTRIBUTION.—Mexico: Maiz, S.L.P. (no date). Guatemala: Volcan de Atitlan, 2,500–3,500 ft. (no date); Grutas de San Pedro Martir, Escuintla (August).

REMARKS.—This species is related to P. pugnax, but it is readily distinguished by the development of costal and saccular processes on the valvae and the size and shape of the cornuti in the male genitalia. In the female genitalia the shape of the dorsal edge of the ostium readily separates P. resurgens from P. pugnax.

The host plant recorded for this species is based on a single reared specimen in the NMNH labeled “reared from Laelia leaf (cocoon on).” Since the other known host plants in this genus are rather far removed from the orchids, it is rather doubtful that Laelia is the primary host. It would seem far more likely that the Laelia was utilizing the same host plant and the specimen accidentally pupated on the Laelia leaf. Further support for this speculation is provided by the fact that species of Byrsonima, known to be a host for one species of Peleopoda, are good orchid hosts and in Central America are very likely to have Laelia and other Laelia- like orchids growing on them. Under such circumstances a chance pupation on the orchid rather than the primary host could easily occur.

I have one specimen of what undoubtedly is a new species from Teffe, Brazil, which is very closely related to P. resurgens. The lack of adequate material precludes the description of this taxon at this time; mention is made here, however, in order to note its relationship to this species. The valvae of the undescribed species are much more elaborately developed and the coloration of the wings is much darker than that of P. resurgens.

Forewing whitish with margins narrowly shaded with brownish-yellow; a small brown spot at end of cell; entire wing sprinkled with brown scales; cilia pale yellow basally, white beyond. Hind wing shining white, cilia white.

MALE GENITALIA (slide JFGC 11182).—Uncus bifid, short. Gnathal plate divided. Anellus subrectangular, lateral lobes very small. Valvae slighty asymmetrical, simple, dilated apically. Aedeagus short, approximately twice as broad basally as apically, vesica armed with two cornuti, one short, broad with bladelike apex, one long, slender, needlelike.

FEMALE GENITALIA (slide WDD 3562).—Ostium bursae sclerotized, extruded beyond the body wall. Ostium with ventral, medial cleft extending to posterior edge of sternite 7. Ductus bursae sclerotized from inception of ductus seminalis to midpoint, membranous beyond. Corpus bursae membranous, signa consisting of two sclerotized plates with invaginated median keel.

TYPE.—In the British Museum (Natural History).

TYPE LOCALITY.—San Geronimo, Baja Vera Paz, Guatemale (pugnax). Tabernilla, Canal Zone, Panama (acompsa). Maracay, Venezuela (monotona).

Costa Rica: 9 mi NW Esparta (July); San Jose (no date). Venezuela: Maracay (August, November), Caracas (no date). Trinidad: Simla, Arima Valley (February); no specific locality (February). Colombia: Atlantico, Quatro Bocas (January). El Salvador: 13 km N San Salvador (February). Guatemala: Baja Vera Paz, San Geronimo (no date).

REMARKS.—This species is closely related to P. arcanella and P. resurgens. The male and female genitalia, however, provide a number of distinguishing characters. In the males, the shape of the valve and armature of the aedeagus readily separate P. pugnax. In the females the ventral, medial cleft of the ostium readily distinguishes this species.

I have examined the type of P. pugnax, a female without abdomen, and that of P. acompsa and found the two identical. The principal differences between the two in the original descriptions are size and a slight variation in maculation. The size factor is due to a sex differential, P. pugnax being described from a single female and P. acompsa from a single male. The maculation difference is insignificant when a large series of specimens from throughout the range of the species is examined. Since the type of P. pugnax is without abdomen it was impossible to examine the genitalia, but specimens from El Salvador which agreed in size and maculation with the type had identical genitalia to those of P. acompsa. A previous study (Duckworth, 1966) of Amsel types revealed the synonomy of P. monotona with this species.

The known distribution of P. pugnax follows closely the distribution of the host plant as given by Standley (1923). Standley lists Byrsonima crassifolia (L.) as occurring in Mexico from Sinaloa to Chiapas and Veracruz, Central America, West Indies, and northern South America.

Alar expanse, 18–20 mm.

Antenna white. Labial palpus white, second segment shaded with brown exteriorly. Head, thorax white. Legs white, fore- and midlegs shaded with brown in some specimens. Forewing white, costa narrowly edged with pale yellow in most specimens, maculation varies from uniform white to white with pale yellow patch at end of cell containing a few brown scales and entire wing randomly sprinkled with few to many brown scales; cilia white, in some specimens pale yellow basally. Hind wing white; cilia white.

MALE GENITALIA (JFGC 11196).—Uncas bifid, short; gnathal plate divided. Anellus reniform, without lateral lobes. Valvae symmetrical; broad basally tapering sharply near midpoint to rounded apex which bears thornlike process from coastal edge. Aedeagus long, near uniform width throughout, vesica armed with one long, sinuate cornutus which slightly exceeds the aedeagus in length, recurved apically with a short, thornlike process at tip.

FEMALE GENITALIA (WDD 3826).—Ostium bursae sclerotized, extruded beyond body wall. Ostium with ventral edge broadly excavated. Ductus bursae membranous, with sclerotized diverticulum at junction with ostium bursae. Corpus bursae small, membranous, without signum.

TYPE.—In the Museum of Comparative Zoology, Harvard University.

TYPE LOCALITY.—Texas (pipertatella); Texas (albella); Alpine, Texas, 7,000 ft. (montivola).

HOST PLANT.—Unknown.

DISTRIBUTION.—Texas: Dallas (no date); San Antonio (April); Brewster County, 7,000 ft. (April); Alpine, 6,000–7,000 ft. (April, May); Bosque County (March).

REMARKS.—This species is closely related to P. flaccescens, but, there are a number of distinguishing characteristics in the male genitalia. The shape of the valvae is completely different with P. piperatella possessing a thornlike processs from the apex which is absent in P. flaccescens. Also, the shape and armature of the aedeagus are quite distinctive in the two species and readily separate them. The female of P. flaccescens is not known so comparison of the female genitalia is not possible.

Examination of the genitalia of the types of H. albella Chambers and D. montivola Meyrick indicates that these two species are synonymous with Zeller’s P. piperatella. The species is somewhat variable in maculation and undoubtedly this variation was responsible for the description of the two synonymns. For many years Chamber’s H. albella stood as a synonym of Antaeotricha vestalis (Walsingham), a species of Stenomidae. Duckworth (1964), however, removed P. albella from synonymy and placed it in the genus Durrantia.

Forewing white, costa narrowly edged with pale yellow, spot at end of cell indistinct, pale yellow; cilia white. Hind wing white; cilia white.

MALE GENITALIA (WDD 3831).—Uncus bifid, short, setiferous. Gnathal plate divided. Anellus rectangular, indented dorsally and laterally, without lateral lobes. Valvae symmetrical; narrow, sharply constricted near midpoint, then very wide before tapering to acute apex. Aedeagus slightly curved, near uniform width throughout except apex, vesica without cornuti.

REMARKS.—This species is nearest the preceding species P. piperatella, and the distinguishing characters have been discussed in the remarks pertaining to that species.

This species is known only by the type and one additional specimen in the NMNH from western Venezuela. At first glance the distribution might appear rather disjunct; both localities, however, are at the eastern base of the Andes at approximately the same altitude and in the same type habitat. It is very likely that the species range is even greater than indicated by the known distribution.

Clarke (1955) illustrates the male genitalia and left wings of the type in the British Museum (Natural History) and the male specimen in the NMNH agrees completely with it.

Alar expanse 17–19 mm.

Antenna white basally, slightly shaded with brown beyond. Labial palpus white, second segment slightly shaded with brown exteriorly. Head white. Thorax white, lightly shaded with brown dorsally. Legs white, forelegs shaded with brown. Forewing yellow-white, costal one-half suffused with brown, a dark brown marginal shade extends along termen and is broken into brown spots from apex to beginning of costal cilia; spot at end of cell, spot in middle of cell, spot in fold, dark brown, cilia yellow-white, heavily shaded with dark brown at tornus. Hind wing white, cilia white.

MALE GENITALIA (WDD 3825).—Uncus bifid, each arm somewhat bulbous at apex and with dorsolateral keel. Gnathal plate fused, spines divided at midpoint into two patches. Anellus small, trifoil, without lateral lobes. Valvae asymmetrical, costal margins heavily sclerotized from base developed into prominent process near midpoint, bases of sacculus broad, fan-shaped, left valva with small setiferous lobe below costa, dentate flange on dorsum of sacculus. Aedeagus short, sharply curved at midpoint, ventrally membranous from midpoint; vesica without cornuti.

TYPE LOCALITY.—Bugaba, Chiriqui, Panama, 800–1,500 ft.

HOST PLANT.—Unknown.

DISTRIBUTION.—Venezuela: Rancho Grande, Aragua, 1100 m (January) Panama: Bugaba, Chiriqui, 800–1,500 ft. (no date).

REMARKS.—This species does not appear to be closely related to any other species in the genus. The female is unknown and of the two existing male specimens of the species, only one has an intact abdomen. Very likely additional specimens of both sexes would permit a clearer assessment of the relationship with other species in the genus.

P. spudasma is readily separated from the other species in the genus by the shape of the arms of the uncus and the valvae with heavily sclerotized costa developed into a prominent process in the male genitalia.

Although the localities are somewhat disjunct, I have compared the specimen from Venezuela with the type specimen and they agree perfectly in all aspects. The type is without abdomen so it was impossible to compare characters of the genitalia.

Publication in Smithsonian Contributions to Zoology

Manuscripts for serial publications are accepted by the Smithsonian Institution Press, subject to substantive review, only through departments of the various Smithsonian museums. Non-Smithsonian authors should address inquiries to the appropriate department. If submission is invited, the following format requirements of the Press will govern the preparation of copy. (An instruction sheet for the preparation of illustrations is available from the Press on request.)

Copy must be typewritten, double-spaced, on one side of standard white bond paper, with 1½″ top and left margins, submitted in ribbon copy with a carbon or duplicate, and accompanied by the original artwork. Duplicate copies of all material, including illustrations, should be retained by the author. There may be several paragraphs to a page, but each page should begin with a new paragraph. Number consecutively all pages, including title page, abstract, text, literature cited, legends, and tables. The minimum length is 30 pages of typescript and illustrations.

The title should be complete and clear for easy indexing by abstracting services. Taxonomic titles will carry a final line indicating the higher categories to which the taxon is referable: “(Hymenoptera: Sphecidae).” Include an abstract as an introductory part of the text. Identify the author on the first page of text with an unnumbered footnote that includes his professional mailing address. A table of contents is optional. An index, if required, may be supplied by the author when he returns page proof.

Two headings are used: (1) text heads (boldface in print) for major sections and chapters and (2) paragraph sideheads (caps and small caps in print) for subdivisions. Further headings may be worked out with the editor.

In taxonomic keys, number only the first item of each couplet; if there is only one couplet, omit the number. For easy reference, number also the taxa and their corresponding headings throughout the text; do not incorporate page references in the key.

In synonymy, use the short form (taxon, author, date, page) with a full reference at the end of the paper under “Literature Cited.” Begin each taxon at the left margin with subsequent lines indented about three spaces. Within a taxon, use a period-dash (.—) to separate each reference. Enclose with square brackets any annotation in or at the end of the taxon. For references within the text, use the author-date system: “(Jones, 1910)” or “Jones (1910).” If the reference is expanded, abbreviate the data: “Jones (1910, p. 122, pl. 20: fig. 1).”

Simple tabulations in the text (e.g., columns of data) may carry headings or not, but they should not contain rules. Formal tables must be submitted as pages separate from the text, and each table, no matter how large, should be pasted up as a single sheet of copy.

For measurements and weights, use the metric system instead of (or in addition to) the English system.

Illustrations (line drawings, maps, photographs, shaded drawings) can be intermixed throughout the printed text. They will be termed Figures and should be numbered consecutively; however, if a group of figures is treated as a single figure, the individual components should be indicated by lowercase italic letters on the illustration, in the legend, and in text references: “Figure 9b.” If illustrations (usually tone photographs) are printed separately from the text as full pages on a different stock of paper, they will be termed Plates, and individual components should be lettered (Plate 9b) but may be numbered (Plate 9: figure 2). Never combine the numbering system of text illustrations with that of plate illustrations. Submit all legends on pages separate from the text and not attached to the artwork.

In the bibliography (usually called “Literature Cited”), spell out book, journal, and article titles, using initial caps with all words except minor terms such as “and, of, the.” (For capitalization of titles in foreign languages, follow the national practice of each language.) Underscore (for italics) book and journal titles. Use the colon-parentheses system for volume, number, and page citations: “10(2): 5–9.” Spell out such words as “figures” and “plates” (or “pages” when used alone).

For free copies of his own paper, a Smithsonian author should indicate his requirements on “Form 36” (submitted to the Press with the manuscript). A non-Smithsonian author will receive 50 free copies; order forms for quantities above this amount with instructions for payment will be supplied when page proof is forwarded.
