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 Folklife Studies

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

Flint, Oliver S., Jr. Studies of Neotropical Caddisflies, XXXIX: The Genus Smicridea in the Chilean Subregion (Trichoptera: Hydropsychidae). Smithsonian Contributions to Zoology, number 472, 45 pages, 146 figures, 14 maps, 1989.—The genus Smicridea McLachlan is characterized for its adult, larval, and pupal stages, and the species found in the Chilean Subregion are revised.

Fourteen species are recognized in the subgenus Smicridea. These are placed in three species groups, with two additional species left unassigned. The S. annulicornis species group includes six species: annulicornis (Blanchard) (Rhyacophylax chilensis Navás, new synonym); decora (Navás) (Antarctopsyche annulicornis Ulmer and A. albescens Navás, new synonyms); manzanara, new species; penai, new species; pucara, new species; and tregala, new species. The S. frequens species group includes four species: anticura, new species; frequens (Navás); mucronata, new species; and turgida, new species. The S. smilodon species group includes two species: redunca, new species; and smilodon, new species. Smicridea complicatissima, new species, and S. matancilla, new species, are not assigned to a species group.

The subgenus Rhyacophylax contains only a single species in the Chilean Subregion: S. marina McLachlan, with Rhyacophylax magnus Ulmer, R. mendocensis Navás, and Smicridea (R.) zanclophora Flint as new synonyms.

Descriptions, figures of males and females, distribution maps, and keys are included for all recognized species of Smicridea of the Chilean Subregion (except for females of S. complicatissima and S. matancilla, which are unknown). The possible relationships of the Chilean members of Smicridea are discussed, and the morphological similarities of members of the S. frequens species group to the Australian genera Asmicridea and Smicrophylax are noted.

Introduction

The trichopterous fauna of Chile has been extensively studied for over a century. The first few Chilean caddisflies were described in the pioneering entomological studies of Blanchard (1851), Mabille (1888), and McLachlan (1871). In the first half of this century the field was dominated by the works of Banks (e.g., 1903), Navás (1918 through 1934), and Ulmer (1904 through 1913). Their works, typical of the era, were based primarily on external characters, with only slight usage of the genitalia. Beginning with Mosely (1934) in the 1930s, and continuing with Flint (1967 through 1983), Holzenthal (1986), and Schmid (1949), the use of genitalic characters has become standard in species discrimination. The types of many of the older species now have been restudied and their identities made known with modern illustrations of their genitalia. This state of knowledge, combined with extensive collections made in recent decades from throughout the Subregion, has resulted in a fauna that is very well known and quite easily identified.

The hydropsychid genus Smicridea McLachlan has remained an outstanding exception to this generalization. Six species of Smicridea were proposed between 1851 and 1932; three of these were illustrated by Schmid (1949), but the others remained poorly known. The genus is, however, widespread and very abundant; few collections that I have studied during the past 20 years did not contain representatives of Smicridea. Study of the original and subsequent descriptions, primary types, and constantly accumulating material have convinced me that errors of identification were common and that the taxonomic situation in the genus was exceedingly complex. Work was begun on a revision in the late 1970s and has progressed erratically ever since as new material has forced me to change my concepts frequently. For the last few years new material has been referable to known species and the taxonomic situation has seemed to stabilize.

I now recognize four of the preexisting species names as valid, and describe, herein, 11 new species of Smicridea. Many of these, especially in the annulicornis and frequens species groups, are exceedingly similar morphologically. However, after study of, and experience with, specimens, I am confident that other workers will be able to identify their material readily.

This, then, is a straightforward taxonomic revision of the species of the genus Smicridea found in the Chilean Subregion of the Neotropical Region. I define the Chilean Subregion (Flint 1983:1–2) as including all of Chile, and Argentina south of the ríos Neuquén and Negro.

LOCALITIES.—In 1975 the Chilean government reorganized their larger administrative units, establishing 12 Regions (generally referred to in Chile as Región I to XII) plus Metropolitana de Santiago and Territorio Chileno Antártico (Map 1). Within these regions are a series of 52 provinces. The country was previously divided into 24 provinces. Many of the province names are the same in both the old and the new systems. However, some old provinces were elevated to regions and divided into three to seven new provinces. Some old provinces did not change at all, but some had their boundaries redrawn, and a few totally disappeared.

This paper uses the new provincial terminology throughout. This means that in many cases the provincial names used differ from those that appear on the specimen labels, which are all labelled using the old provincial system. The appropriate new provincial names were determined by finding localities on a map labelled with the new names.

Locality information listed under the “Material Examined” section is essentially quoted from specimen labels. A number of localities were unknown to me, or the label data were insufficient to locate the site. I have attempted to ascertain the situation of these localities from the collector or a gazetteer and, when discovered, have included this or other supplemental data in brackets.

Within the “Type Material” sections, information quoted separately represents information from separate specimen labels.

ACKNOWLEDGMENTS.—This study was made possible only by the accumulation of large amounts of material from many localities, often in long series. This was accomplished primarily through the efforts of the eminent Chilean field naturalist, Sr. Luis E. Peña G. of Santiago, Chile. Since the late forties he has collected caddisflies and sent them to specialists for study: the first ten years to Dr. F. Schmid (he and this material now located at the Canadian National Collection, Ottawa), and since 1965 to me at the National Museum of Natural History (NMNH). These collections have been supplemented by those I have made during seven trips to the Subregion and by two made by Dr. D.R. Davis (NMNH). Extensive collections were also received for study from Dr. E.S. Nielsen from the Zoological Museum, University of Copenhagen.

I thank the following curators for allowing me to study primary types in their collections: Dr. P.C. Barnard, British Museum (Natural History), for S. murina McLachlan; Mlle S. Kellner-Pillaut, Muséum Nacional d'Histoire Naturelle, for S. annulicornis (Blanchard); Dr. F. Español C., Museo de Zoologia, Barcelona, for S. chilensis (Navás), S. decora (Navás), and S. frequens (Navás); and Dr. G. Petersen, Deutsches Entomologisches Institut, for S. albescens (Navás).

Mrs. Elaine R.S. Hodges (NMNH) prepared Figure 1, inked all the drawings, prepared the plates, and provided other valuable artistic support. Mr. George L. Venable (NMNH) prepared Figure 17. Drs. R.W. Holzenthal, University of Minnesota, and W.N. Mathis, NMNH, reviewed the manuscript of this paper, correcting many errors and making valuable suggestions. I am indebted to all of these individuals for their indispensable contributions.

The genus Smicridea is found from Colorado and Oklahoma in United States south to 46°S latitude in South America. Further collecting will probably extend its known range at least as far as the Straits of Magellan. Smicridea's apparent absence in northern Chile is probably real, resulting from that area's aridity.

Species of Smicridea are also common on the Greater and larger Lesser Antillean islands. Species were described from Australia and Tasmania (Mosely and Kimmins, 1953), but these have now been transferred to Asmicridea or Smicrophylax (Nebois, 1977, 1986).

The genus is both speciose, with over 100 described species, and very abundant in field collections. The larvae are found in flowing waters, from small spring seeps to the largest rivers. They use trap nets constructed on the substrate to strain out their food of particulate organic matter from the flowing water.

ADULT.—Ocelli absent. Spurs 1, 4, 4, or 1, 4, 2. Maxillary palpus (Figure 4) with first 4 segments short, fifth longer than basal four and multiarticulate, second segment with several rows of stout setae apically. Labial palpus (Figure 5) with first 2 segments short, third longer than first two, and articulate. Antenna no longer than forewing. Head dorsally (Figure 3) lacking well-developed sutures; with anteromesal and posterolateral warts well developed, anterolateral warts present but only weakly delimited. Meso- and metanota (Figure 2) without setal warts (but with areas of setae). Forewing (Figures 6, 7) without specially modified hairs on vein 1A; hind wing with R₂₊₃ undivided, M arising from R basally.

LARVA.—Labrum (Figure 8) simple, with large anterolateral brushes, dorsal surface sparsely setate. Mandibles with lateral surface bearing narrow dorsal and ventral flanges, with setae between; mesal face bearing a variable number and form of teeth; left mandible with a brush of setae. Labium (Figure 9) with submentum not deeply cleft apicomesally. Frontoclypeus with lateral margin not, or barely, expanded posterolaterally. Trochantin (Figure 10) a simple conical projection. Prosternum transverse without posterolateral sclerites. Pronotum divided on midline; meso- and metanotum entire. Abdomen without lateral line fringe; eighth and ninth sterna with sclerites bearing numerous setae; body surface with setae flattened and scalelike. Gills consisting of a central stalk generally bearing several whorls of smaller lateral filaments. Mesosternum with 1 pair of gills, metasternum with 1 or 2 pairs; abdominal segments 1–6 with a pair of ventral gills, segments 1–7 with a more lateral pair of ventral gills that consist of 2 stalks on segments 2–7; with 1 to 3 single, small filaments laterally on each side of segments 3–7. Anal claw without ventral teeth; brush well developed.

FIGURES 2–7.—Adult structures. Smicridea (S.) fasciatella McLachlan: 2, thorax, dorsal, anterior towards top; 3, head, dorsal; 4, left maxillary palpus, lateral; 5, left labial palpus, lateral; 6, wing venation. Smicridea (R.) signata (Banks): 7, wing venation.

Mandibles (Figure 16) inflated basally and bearing setae laterally and posteriorly on this portion; tapering regularly to a pointed apex, inner margin with large teeth near base and minutely serrate beyond. Head anteriorly with numerous setae. Antennae reaching tip of abdomen. Tarsus of midleg broadened and bearing lateral fringes. Thorax and abdomen with sparse setae; lacking lateral line fringe. Abdomen with broad single or bifid lateral gills; ventrally with branched gills. Hook plates (Figure 13) anteriorly on segments 2–8, posteriorly on 3 and usually 4. Apical processes (Figure 15) rodlike, bearing an apical brush of stout setae.

FIGURES 13–17.—Pupal structures. Smicridea (S.) annulicornis (Blanchard): 13, hook plates, dorsal (A=anterior, P=posterior, 2–8=segment number). Smicridea (S.) fasciatella McLachlan: 14, labrum, dorsal; 15, apical appendages, dorsal; 16, mandibles, ventral; 17, habitus, dorsal.

COMMENTS.—The name Antarctopsyche is a junior, subjective synonym of subgenus Smicridea, whereas Pellopsyche and Badallus are junior, subjective synonyms of the subgenus Rhyacophylax.

The above diagnoses (from Flint, 1974a) are based primarily upon the type species of the genus, S. fasciatella McLachlan, but have been emended where necessary to include known divergences in other recently discovered species of the genus.

The immature stages of the species treated herein have not been studied in detail, but those of the species known to me agree with the general diagnoses. However, there are some unusual modifications in certain of the species. Most larvae are quite typical in appearance, although varying considerably in vestiture of the abdomen, color pattern of the head, shape of the anterior margin of the frontoclypeus, etc. The larvae of redunca and smilodon, new species, have the head concave frontally with this area surrounded by a raised carina. The pupae offer some unusual modifications of the hook plates, although most species have the usual paired plates. The pupae of annulicornis (Blanchard) and manzanara, new species, have plate 4P fused mesally, forming a single transverse plate (Figure 13). Smicridea decora (Navás) has 5A fused also. The various species also differ greatly in the length and setation of their apical processes.

Key to Subgenera of Smicridea

Subgenus Smicridea McLachlan

The adults of this subgenus are characterized by several venational characteristics. In the forewing the two posterior crossveins (between M and Cu and Cu₁ and Cu₂) are separated from the crossveins connecting R and M by a distance two or more times that of the crossvein m-cu. In the subgenus Rhyacophylax all crossveins in the forewing are nearly in alignment. In the hindwing of the subgenus Smicridea, R₂₊₃ and R₄₊₅ are subparallel, R₄₊₅ is about as long as R₄ or R₅, crossvein r is present (although weak), and the basal portion of the radiomedial system is well separated from Cu₁. Subgenus Rhyacophylax, in contrast, has R₄₊₅ strongly divergent from R₂₊₃ basally, R₄₊₅ is about half as long as either R₄ or R₅, there is no crossvein r, and the basal portion of the radiomedial system is closely approximate to Cu basad of its apical fork. Subgenus Smicridea possesses in the male two pairs of internal, reticulate sacs in the subapical abdominal segments. Reticulate sacs are totally lacking in subgenus Rhyacophylax. In addition the hindlegs of subgenus Smicridea have two pairs of spurs, whereas subgenus Rhyacophylax males lack the spurs at midlength.

The species of the subgenus Smicridea that are treated here are placed into three species groups, except that two species that clearly do not belong in any currently recognized species group are left unplaced at this time.

The annulicornis species group contains annulicornis (Blanchard), decora (Navás), manzanara, new species, penai, new species, pucara, new species, and tregala, new species. These are characterized by the phallus of the male genitalia terminating in paired, lateral sclerites, cuplike mesally, that are longer than high, and the apicodorsal margin of the phallotheca not projecting significantly over the bases of the lateral sclerites. In the female, the eighth sternite does not have the mesal margin sharply constricted, although sometimes it is distinctly concave. The clasper receptacle is always a well developed pocket, often with the mesal face bearing dark reticulations. The species are quite large, with forewing length from 6–13 mm.

The frequens species group is very similar to the annulicornis species group, and contains anticura, new species, frequens (Navás), mucronata, new species, and turgida, new species. The male genitalia are similar to those of the preceeding species group, but the lateral sclerites of the phallus are much shorter, usually as high as long, and the apicodorsal margin of the phallotheca projects, hoodlike, over the bases of the lateral sclerites. The eighth sternites of the female are sharply constricted on the mesal margin, resulting in a distinct, hatchet-like, apical lobe. The clasper receptacle is variable; rarely pocket-like, generally only deeply impressed, or rarely wholly lacking, and never is the cuticle darkly reticulate. The species are small, being 5–8.5 mm in forewing length.

The smilodon species group is not obviously related to any other New World group of species. It contains redunca, new species, and the closely similar smilodon, new species. They agree in having the apex of the phallus greatly modified and bearing paired apical knobs and large ventral hooks. The females are most similar to females of the annulicornis species group, but have a rather long eighth sternite with the basolateral angle greatly prolonged. The clasper receptacle is not pocket-like, but is very deeply impressed and the cuticle is not reticulate. The posteriomost of the vaginal sclerties is elongate and pyriform rather than short and transverse. The species of this group are also rather small, the forewings measuring 5.5–6.5 mm.

Smicridea complicatissima, new species, and S. matancilla, new species, are not assigned to a species group. They do not clearly fit into any currently recognized New World species group of the genus, nor do they seem related to each other, although they both posses very unusual phalli with processes or spines not seen elsewhere. The females are unknown for both species, thus there is no evidence about placement from this stage. They too are rather small with forewing lengths of 5–7 mm.

Smicridea (S.) chilensis (Navás).—Flint, 1974b:88.

This, one of the most ubiquitous caddisflies in the Chilean Subregion, appears to be most closely related to S. decora. The two are usually easily distinguished by the darker color and smaller eyes of annulicornis. The deeply cupped lateral plates of the phallus that lack any mesobasal shoulder and the very small or lacking dorsolateral lobes are diagnostic in the male genitalia of annulicornis. The genitalia of the female are similar to that of decora, but may be recognized by the shape of the clasper receptacle. In decora the outer face is unmodified, but in annulicornis there is a distinct, oblique posteroventral fold overhanging the opening slightly and a similar, but smaller, one anteroventrally.

ADULT.—Length of forewing, 6–10 mm. Color brown, appendages slightly paler, antennae annulate; forewings pale brownish, variable, marked with dark brown flecks, often producing a distinct pattern, other times producing a more uniform speckling. Eye of male in frontal aspect with diameter slightly greater than half of interocular distance. Fifth sternum with anterolatereral processes slightly longer than sternum; with 2 pairs of internal sacs, anterior pair as long as its segment, posterior pair distinctly shorter than its segment.

Male Genitalia: Ninth segment with anterior margin nearly vertical. Tenth tergum elongate, tip divided dorsomesally; tergite with apex rounded in dorsal, and enlarged and upturned in lateral aspect. Clasper with basal segment inflated apicad; apical segment elongate, bluntly pointed. Phallus tubular, base at right angles to stem, width of basal opening slightly more than twice diameter of stem, apex distinctly enlarged; lateral plate 1½–2 times longer than broad, ventral margin well above ventral margin of stem, in ventral aspect with mesobasal shoulder lacking, deeply cupped, and with inner margins slightly concave but with ventral margin usually more lateral than dorsal; dorsolateral lobe very small, or sometimes apparently lacking.

Female Genitalia: Eighth sternite roughly rectangular, with posteromesal angle at about 90°; anterolateral angle produced, rounded. Ninth tergum strongly produced anteroventrally. Clasper receptacle deep, pocket-like, produced ventromesally; in dorsal aspect about ½ length of tergum, in lateral aspect with a narrow anterior overhang and a broader, oblique posteroventral overhang. Vaginal sclerite narrow, transversely oval, with a small posteromesal lobe bearing a small opening.

TYPE MATERIAL.—Hydropsyche annulicornis Blanchard, type in MNHNP labeled: “MUSEUM PARIS Chili Gay 15–43”; “15–43”; “TYPE”; “Smicridea annulicornis Blanch (Blanchard's Type von Hydropsyche annulicornis Blanch. Ulmer vid. 1913).”

Rhyacophylax chilensis Navás: Type in MZB labeled: “Marga Marga (Chile) 1. 1919”; “Rhyacophylax chilensis Nav. P. Navas S.J., det.”; “Typus.” The pin is bare except for a balsam mount on the pin with art genitalia. However, both the original description and Schmid (1949) state that the type is a art! The art genitalia are annulicornis as are most other specimens determined as chilensis by Navás, and other examples from Estero Marga Marga at Los Perales. Based on this evidence about the identity of the type, I make this synonymy.

This species appears to be closely related to annulicornis by the structure of its genitalia, but is easily recognized by its generally whiter appearance and very large eyes of the male. The genitalia of the males of the two species are more difficult to distinguish, with decora tending to have proportionately broader lateral plates of the phallus with a more well-developed mesobasal shoulder. The female genitalia also show close similarity to those of annulicornis. In the latter species there is a distinct oblique lip posteroventrally across the opening of the pocket, but in decora there is only the simple curved dorsal margin.

ADULT.—Length of forewing, 8–13 mm. Color pale brown, with much white hair, antennae annulate; forewing mostly whitish with sparse brown marks often forming 2 conspicuous obliquely-transverse dark bands. Eye of male in frontal aspect with diameter almost as large as interocular distance. Anterolateral processes of fifth sternum slightly longer than sternum, with 2 pairs of internal sacs each only slightly longer than half length of segment within which it lies.

Male Genitalia: Ninth segment with anterior margin nearly vertical. Tenth tergum elongate, tip divided apicomesally; tergite rounded in dorsal, and enlarged and upturned in lateral aspect. Clasper with basal segment inflated apicad, apical segment elongate and bluntly pointed. Phallus tubular, basal portion at a 110° angle to stem, width of basal opening 4 times diameter of narrowest part of stem, apex only slightly inflated; lateral plate about as long as wide, ventral margin displaced from ventral margin of stem, in ventral aspect with a well developed mesobasal shoulder, deeply cupped and with mesal margin almost straight, dorsolateral lobe small.

FIGURES 27–35.—Smicridea (S.) decora (Navás). Male genitalia: 27, lateral; 28, dorsal. Tip of phallus: 29, lateral; 30, ventral; 31, dorsal. Female genitalia: 32, lateral; 33, dorsal; 34, vagina, ventral; 35, eighth sternite, ventral.

Female Genitalia: Eighth sternite elongate, with posteromesal angle rounded, anterolateral angle produced, apex angulate. Ninth tergum produced almost totally ventrad. Clasper receptacle deep, pocket-like, produced ventromesally; in dorsal aspect about ⅓ length of tergum; in lateral aspect with a continuous, deeply sinuate anteroventral overhang. Vaginal sclerite narrow, transversely oval, with a small posteromesal sclerite bearing a small opening.

TYPE MATERIAL.—A. annulicornis Ulmer, type, in “Berliner Museum,” not seen, but description (very large eyes) and figure of art genitalia could only be the species here treated.

Smicridea (Smicridea) manzanara, new species

FIGURES 36–45; MAP 4

Although related to penai and pucara, this species is the most easily recognized of the three. The very long lateral plates of the phallus and, especially, the long slender dorsolateral lobes of the phallus are diagnostic. The differences in the females of the three species are rather slight. The deep, rounded clasper receptacle, with a large, reticulate surface area anteriad in combination with the distinctive anterior knobs of the internal plate offer the best means of identification.

ADULT.—Length of forewing, 10–11.5 mm. Color pale brown; appendages slightly paler, antennae annulate; forewing pale brown marked with darker brown flecks, generally producing an indistinct pattern. Eye of male in frontal aspect distinctly less in diameter than half of interocular width. Anterolateral process of fifth sternum distinctly larger than segment; with 2 pairs of internal sacs, each slightly shorter than segment within which it lies.

Male Genitalia: Ninth segment with anterior margin nearly vertical. Tenth tergum elongate with apex divided apicomesally; tergite with tip rounded in dorsal, upturned and pointed in lateral aspect. Clasper with basal segment slightly inflated apicad, paralled-sided basally; apical segment short, bluntly pointed. Phallus tubular, base at 110° angle to stem, width of basal opening less than 3 times the width of narrowest part of stem, apex inflated; lateral plate at least 3 times as long as broad, ventral margin confluent with venter of stem, in ventral aspect with mesobasal shoulder distinct, shallowly cupped, with dorsal and ventral margins deeply concave, dorsolateral lobe long and slender, nearly attaining apex of lateral plate.

FIGURES 36–45.—Smicridea (S.) manzanara, new species. Male genitalia: 36, lateral; 37, dorsal. Tip of phallus: 38, lateral; 39, ventral; 40, dorsal. Female genitalia: 41, lateral; 42, dorsal; 43, vagina, ventral; 44, internal plate, dorsal; 45, eighth stemite, ventral.

Female Genitalia: Eighth sternite elongate, inner margin sinuate, posteromesal angle produced and truncate, anterolateral angle produced, obliquely truncate. Ninth tergum produced ventrad and anteriad, very broad laterally. Clasper receptacle with inner surface strongly reticulate, produced mesally and posteroventrally, deep and pocket-like, with a large clasper groove anteriad; in lateral aspect with a deep ventral overhang on the surface of which is an oblique dark mark. Vaginal sclerites lightly sclerotized; posterior sclerite, trans4 arterse, with a darkened posteromesal lobe, anterior sclerite, trans4 arterse, darkened posteromesally. Internal plate darkened, with lateral arms produced posteriad and bearing distinct dark knobs from anterior margin.

Smicridea (Smicridea) penai, new species

FIGURES 46–55; MAP 5

This species, closely related to pucara and less so to manzanara, is recognized with certainty only by structures of the male phallus. In penai, the lateral plates are sharply upturned at the apex and more elongate with a larger mesobasal shoulder in ventral aspect. The females clasper receptacle is large and rounded in lateral aspect in this species, while the vaginal sclerites are distinctly formed and strongly sclerotized mesally.

ADULT.—Length of forewing, 9–11 mm. Color brown, appendages slightly paler, antennae annulate; forewing pale brown generally evenly flecked with dark brown, sometimes showing a distinct pattern. Eye of male in frontal aspect with diameter half that of interocular distance. Anterolateral process of fifth sternum length of sternum; with 2 pairs of internal sacs, each distinctly shorter than sternum.

Male Genitalia: Ninth segment with anterior margin nearly vertical. Tenth tergum elongate, tip divided apicomesally; tergite with tip rounded in dorsal, enlarged and upturned in lateral aspect. Clasper with basal segment inflated apicad; apical segment elongate, bluntly pointed. Phallus tubular, base at right angles to stem, width of basal opening 3–4 times width of narrowest part of stem, apex distinctly enlarged, lateral plate slightly longer than wide, ventral margin confluent with ventral margin of stem, tip sharply upturned, in ventral aspect with mesobasal shoulder distinctly produced mesad, shallowly cupped with ventral margin deeply concave, dorsolateral lobe large, about half as long as lateral plate.

Female Genitalia: Eighth sternite elongate, with posteromesal angle rounded, slightly produced; anterolateral angle produced into an apically enlarged lobe. Ninth tergum produced almost directly ventrad, broad laterally. Clasper receptacle deep, pocket-like, with inner surfaces strongly reticulate, produced mesad, and posteroventraliy; in lateral aspect with a deep posteroventral overhang. Vaginal sclerites with a narrow posterior bar and a broader, anterior sclerite, connected centrally by a strongly darkened structure bearing a posteromesal opening. Internal plate more strongly sclerotized mesad than laterally, with lateral arms extended posteriad, with a distinct knob-like depression centrally.

Smicridea (Smicridea) pucara, new species

FIGURES 56–65; MAP 6

This and penai are most closely related, with manzanara less similar. The apex of the phallus offers the most certain identification. In lateral aspect, the lateral plates of pucara are more evenly rounded apically and shorter, with a smaller mesobasal shoulder in 4 ventral aspect. The clasper groove and receptacle provide the best means of identifying the female. In pucara, the groove is very long and curved, and the receptacle is very shallow in lateral aspect.

ADULT.—Length of forewing, 9.5–11.5 mm. Color grayish brown, appendage paler, antennae annulate; forewing intensely marked with grayish brown flecks, producing a dark pattern. Eye of male in frontal aspect with diameter half that of interocular distance. Anterolateral process of fifth sternum slightly longer than sternum; with 2 pairs of internal sacs as long as segments within which they lie.

Male Genitalia: Ninth segment with anterior margin nearly vertical. Tenth tergum elongate, tip divided apicomesally; tergite with apex somewhat elongate in dorsal, and upturned in lateral aspect. Clasper with basal segment slightly inflated apicad, basal portion parallel-sided; apical segment elongate, bluntly pointed. Phallus tubular, basal portion at right angles to stem, width of basal opening slightly more than 3 times width of narrowest part of stem, apex inflated; lateral plate a bit longer than wide, ventral margin confluent with venter of stem, in ventral aspect with a well developed mesobasal shoulder, shallowly cupped, and with ventral margin deeply concave, dorsolateral lobe large, about half as long as lateral plate.

Female Genitalia: Eighth sternite elongate, posteromesal angle rounded; anterolateral angle produced into an apically enlarged lobe. Ninth tergum produced almost directly ventrad, broad laterally. Clasper receptacle with inner surface strongly reticulate only slightly produced ventromesally, with a long clasper groove; in lateral aspect with a rather shallow posterolateral overhang. Vaginal sclerites very lightly sclerotized, with an indistinct posterior sclerite with a darkened center and a slightly broader, pale anterior sclerite. Internal plate pale, indistinct, with lateral arms indistinctly produced posteriad.

Smicridea (Smicridea) tregala, new species

FIGURES 66–75; MAP 7

This distictive new species of the annulicornis species group is perhaps most easily confused with pucara, new species. The apex of the phallus offers the most distictive characteristics: the midventral keel at the apex of the phallus is distinct, as is the very large and well-defined ventrobasal lobe of the lateral plates. The female genitalia are less distinctive. The row of setae across the opening of the broad, deep clasper receptacle appears to be the best identifying characteristic.

FIGURES 56–65.—Smicridea (S.) pucara, new species. Male genitalia: 56, lateral; 57, dorsal; 58. Tip of phallus: 58, lateral; 59, ventral; 60, dorsal. Female genitalia: 61, lateral; 62, vagina, ventral; 63, dorsal; 64, internal plate, dorsal; 65, eighth sternite, ventral.

ADULT.—Length of forewing, 9–10 mm. Color dark gray-brown, appendages paler, antennae annulate; forewing dark gray-brown, with a few scattered pale flecks. Eye of male in frontal aspect with diameter ⅖ that of interocular distance. Anterolateral process of fifth sternum slightly longer than sternum, with 2 pairs of internal sacs, each as long as segment in which it lies.

FIGURES 66–75.—Smicridea (S.) tregala, new species. Male genitalia: 66, lateral; 67, dorsal. Tip of phallus: 68, lateral; 69, ventral; 70, dorsal. Female genitalia: 71, lateral; 72, vagina, ventral; 73, dorsal; 74, internal plate, dorsal; 75, eighth sternite, ventral.

Male Genitalia: Ninth segment with anterior margin nearly vertical. Tenth tergum elongate; tergite rounded laterally in dorsal, bluntly upturned in lateral aspect. Clasper with basal segment slightly inflated apicad, parallel-sided basally; apical segment elongate, bluntly pointed. Phallus tubular, basal section at 110° angle to stem, basal opening 3 times diameter of narrowest part of stem; apex enlarged, produced into a narrow midventral keel, lateral surfaces produced over base of lateral plate (unless plates are fully everted); lateral plate elongate, with a well-marked ventrobasal lobe in lateral aspect and in ventral aspect cup-like, with ventral margin very concave, dorsal margin straight, mesobasal shoulder well developed; dorsolateral lobe well developed, elongate, lying dorsally over lateral plate.

Female Genitalia: Eighth sternite elongate, posteromesal angle rounded; anterolateral angle very broad, obliquely truncate. Ninth tergum produced almost directly ventrad, broad. Clasper receptacle with inner surface strongly reticulate, deep, pocket-like, produced ventromesally, broadly open dorsally with a row of setae from inner face; in lateral aspect with a broad ventral overhang. Vaginal sclerites lightly sclerotized with a transverse posterior sclerite bearing a darkened central area, and a transversly rectangular anterior sclerite slightly darkened posteromesally. Internal plate lightly sclerotized with lateral arms produced posteriad and with anterolateral thickening.

Smicridea (Smicridea) anticura, new species

FIGURES 76–84; MAP 8

This species is quite similar to mucronata and turgida. From mucronata, it is to be recognized by a basoventral root and the absence of the ventral tooth of the lateral plate. From turgida, anticura is distinguished by the basoventral root being threadlike, the apex of the phallus being narrower, and the very large anterolateral processes of the fifth sternum.

FIGURES 76–84.—Smicridea (S.) anticura, new species. Male genitalia: 76, lateral; 77, dorsal. Tip of phallus: 78, lateral; 79, ventral; 80, dorsal. Female genitalia: 81, lateral; 82, dorsal; 83, vagina, ventral; 84, eighth sternite, ventral.

ADULT.—Length of forewing 5.5–8 mm. Color white, antennae annulate; forewing mostly white, marked conspicuously with scattered dark flecks. Eye of male in frontal aspect with diameter half that of interocular distance. Anterolateral process of fifth sternum very long, 2–2½ times length of sternum; with 2 pairs of internal sacs, each slightly longer than sternite within which it lies.

Male Genitalia: Ninth segment with anterior margin nearly vertical. Tenth tergum elongate; tergite with tip produced slightly and directed mesad in dorsal, and upturned and pointed in lateral aspect. Clasper with basal segment inflated apicad; apical segment elongate and bluntly pointed. Phallus tubular, base evenly curved into stem, basal opening slightly more than twice width of stem, apex distinctly inflated; apex of phallotheca produced into a trilobed plate over lateral plates, in ventral aspect with phallotheca apically broader than lateral plates; lateral plates rounded, cup-like in ventral aspect with a slight development of mesobasal angle, basoventral root large and thread-like; dorsolateral lobe small but distinct, lying laterally near base of lateral plates.

Female Genitalia: Eighth sternite with mesal margin sharply constricted; posteromesal angle nearly at 90°. Ninth tergum produced anteroventrally, broad laterally. Clasper receptacle deep, pocket-like, produced ventromesally; in lateral aspect with receptacle toward posterior third of tergum, with pocket clearly visible beneath broad, vertical overhang. Posterior vaginal sclerite dumbell-shaped with a central opening, anterior sclerite transverse, almost semicircular.

Smicridea frequens (Navás).—Schmid, 1949 [1950]:347–348 [sic Smicridia].—Flint, 1967:55.—Fischer, 1972:144.

Smicridea (S.) frequens (Navás):—Flint, 1974b:88.

This species and mucronata, new species, are very similar in appearance. Both are generally nearly white with dark flecks in coloration. They may only be distinguished with certainty by the structure of the male genitalia, and in particular by the apex of the phallus. In frequens there is, beneath the lateral plates, a small posteroventral plate that bears from its dorsal surface the erect phallotremal sclerites. In mucronata this plate is lacking and the phallotremal sclerites are rounded and central in position. The lateral plates of the phallus in mucronata bear a distinct, mesal tooth basally that is lacking in frequens. The females of these two species are even more difficult to tell apart. The apex of the clasper groove is near the middle of the ninth segment in frequens, but posteriad of the middle in mucronata. The posteriomost of the vaginal sclerites is very indistinct in frequens and usually represented by a pair of small sclerotized points laterally, but in mucronata it is strongly sclerotized, transverse, and bears a central pore.

ADULT.—Length of forewing, 5–8 mm. Color white, antennae annulate; forewings covered with white hairs, usually with a few pale brown spots, sometimes with 2 obliquely transverse pale brown bands. Eye of male in frontal aspect with diameter about half of interocular distance. Anterolateral process of fifth sternum slightly longer than length of sternum; with 2 pairs of internal sacs, each almost 1½ times length of segment in which it lies.

Male Genitalia: Ninth segment with anterior margin nearly vertical. Tenth tergum elongate, tergite obliquely truncate in dorsal view, upturned and pointed in lateral aspect. Clasper with basal segment inflated apically; apical segment elongate and bluntly pointed. Phallus tubular, base at 110° angle to stem, width of basal opening 4 times that of narrowest part of stem; apex slightly enlarged, ventral surface produced into a lip-like lobe beneath lateral plates bearing a pair of erect dark phallotremal sclerites from dorsal surface near center; lateral plate rounded apically with dorsobasal angle produced into a narrow lobe; dorsolateral lobes apparently absent.

Female Genitalia: Eighth sternite with mesal margin deeply constricted, posteromesal angle at about 90°, anterolateral angle greatly produced. Ninth tergum produced mostly anteriad, very broad. Clasper receptacle deeply impressed, produced mesad; in lateral aspect with deepest impression at level of center of tergum, without any visible pocket ventrad of opening. Vaginal sclerites with posterior one reduced to two small, inconspicuous lateral plates, anterior sclerite transverse with anterior margin broadly produced mesally.

Smicridea (Smicridea) mucronata, new species

FIGURES 94–102; MAP 10

As discussed more fully under frequens, these two species are very similar in structure and color. Most material of mucronata tends to be more strongly marked with dark flecks, and it will rarely be entirely in fuscate, a condition never seen in frequens. Differences between the species in males are found in structures at the apex of the phallus, and in females in the position of the clasper receptacle and the vaginal sclerites.

ADULT.—Length of forewing, 6–8.5 mm. Color varying from nearly white to dark gray-brown, appendages stramineous, antennae annulate; forewing varying from almost pure white with a few dark flecks to almost totally gray-brown with a faint pattern of pale flecks. Eye of male in frontal aspect with diameter half that of interocular distance. Anterolateral process of fifth sternum 1½ times length of sternum; with 2 pairs of internal sacs, each slightly longer than segment within which it lies.

FIGURES 94–102.—Smicridea (S.) mucronata, new species. Male genitalia: 94, lateral; 95, dorsal. Tip of phallus: 96, lateral; 97, ventral; 98, dorsal. Female genitalia: 99, lateral; 100, vagina, ventral; 101, dorsal; 102, eighth stemite, ventral.

Male Genitalia: Ninth segment distinctly produced dorsolaterally. Tenth tergum elongate, tergite slightly produced mesally in dorsal, upturned and pointed in lateral aspects. Clasper with basal segment inflated apicad; apical segment elongate, bluntly pointed. Phallus tubular, base curving into stem, width of basal opening barely twice diameter of narrowest part of stem; apex enlarged ventrad, dorsal surface produced slightly over lateral plates; lateral plates ovoid in lateral aspect, in ventral aspect distinctly cupped with ventral angle produced as a point directed mesad; dorsolateral lobe small but distinct, lying laterally near base of lateral plate.

Female Genitalia: Eighth sternite with mesal margin deeply angulate; posteromesal angle slightly less than 90° anterolateral angle strongly produced. Ninth tergum produced strongly ventrad, broad laterally. Clasper receptacle deeply impressed, produced mesad; in lateral aspect with deepest impression toward posterior third of tergum, without any visible pocket beneath posteroventral angle. Posterior vaginal sclerite with lateral parenthesis-like marks and a central pore; anterior sclerite transverse, anterior margin curved.

Smicridea (Smicridea) turgida, new species

FIGURES 103–111; MAP 11

This species seems the most closely related to anticura, new species, but differs in coloration and structure of the apex of the phallus. The color is dark with whiter spots in this species, but in all other species of the group it is basically white with dark flecks. The apex of the phallotheca is distinctly inflated in dorsal aspect in turgida, but nearly parallel-sided in the other species, and the basoventral root of the lateral plate in turgida is short and truncate, but slender and threadlike in anticura. The female of turgida is very easily recognized because the clasper groove is not impressed at all, whereas in all other species it is at least impressed or more commonly pocket-like.

ADULT.—Length of forewing, 6–8 mm. Color brown, appendages paler, antennae annulate; forewing brown, marked with white producing a mottled effect Eye of male in frontal aspect with diameter half that of interocular distance. Anterolateral process of fifth sternum length of sternum; with 2 pairs of internal sacs, very large, 1¼ to 1 ½ times length of segment within which they lie.

Male Genitalia: Ninth segment with anterolateral margin slightly produced dorsad. Tenth tergum elongate; tergite with tip produced slightly in dorsal, produced and upturned in lateral aspect. Clasper with basal segment inflated apicad; apical segment short, blunt. Phallus tubular with base at right angles to stem; basal opening 3 times width of narrowest part of stem; apex enlarged especially in dorsal and ventral aspects; lateral plates deflected somewhat ventrad by development of a bilobed dorsal projection of stem, in ventral aspect with stem much broader than plates; lateral plates rounded, cup-like in ventral aspect with only slight development of mesobasal angle; with basoventral root short and truncate; dorsolateral lobe small but distinct, lying laterally near base of lateral plate.

FIGURES 103–111.—Smicridea (S.) turgida, new species. Male genitalia: 103, lateral; 104, dorsal. Tip of phallus: 105, lateral; 106, ventral; 107, dorsal. Female genitalia: 108, lateral; 109, vagina, ventral; 110, dorsal; 111, eighth sternite, ventral.

Female Genitalia: Eighth sternite with mesal margin deeply sinuate, posteromesal angle rounded. Ninth tergum produced anteroventrally. Clasper receptacle absent; with a shallow dorsolateral clasper groove whose dorsal margin projects slightly in dorsal aspect. Vaginal sclerites with posterior one narrow, dark, strongly curved, with a minute central pore; anterior sclerite broad, anterior margin curved.

Smicridea (Smicridea) redunca, new species

FIGURES 112–120; MAP 12

This species and smilodon, new species, are closely related. They are readily told apart by the male phallus and less confidently by the female clasper receptacle. The male phallus bears a pair of apical lobes that have a ventral point and the ventral hooks are directed basally in redunca; in smilodon the apical lobes lack ventral points and the ventral hooks point directly ventrad. The females of the two species are exceedingly similar; the venter of the clasper receptacle in redunca bears a dark process that is lacking in smilodon.

ADULT.—Length of forewing 6–6.5 mm. Color generally gray-brown, appendages paler; antennae annulate; forewing with ground color pale brown, heavily irrorate with dark brown.

Smicridea (Smicridea) complicatissima, new species

FIGURES 129–132; MAP 13

This morphologically distinct species is of unknown relationship. Unique features include the ventromesal projection of the ninth sternum and the very large phallus that is membranous anteroventrally, lacks any ventral articulation with the clasper bases, and bears numerous spines and a large convoluted median lobe. Although suggestive of some species of the S. nigripennis species group, such as S. tarasca Flint, I believe this resemblance is convergent. All species of the nigripennis species group are black, sometimes with a pair of transverse, white lines, and the phallus is sclerotized anteroventrally and is distinctly articulated with the clasper bases. But complicatissima is a mottled brown color and the entire basoventral region of the phallus is membranous.

FIGURES 129–132.—Smicridea (S.) complicatissima, new species. Male genitalia: 129, lateral; 130, dorsal. Tip of phallus: 131, dorsal; 132, lateral (9S = apex of ninth sternum).

ADULT.—Length of forewing, 7 mm. General color dark brown, appendages paler, antennae annulate; forewing dark brown with scattered pale flecks producing an obscure irroration. Eye of male in frontal aspect with diameter half that of interocular distance. Anterolateral process of fifth sternum slightly shorter than sternum; with 2 pairs of internal sacs each distinctly shorter than the segment within which it lies.

Male Genitalia: Ninth segment with anterior margin vertical; sternum produced posteriad as a broad thin lobe between claspers. Tenth tergum divided apicomesally; tergite short, narrow, and upturned in lateral, and narrow apicad in dorsal aspect; in lateral aspect very broad basally. Clasper with basal segment slightly inflated apicad; apical segment elongate. Phallus with usual sclerotized anteroventral margin and articulation with clasper bases lost and area membraneous (ninth sternal process seeming to serve as a support or have an articulatory function with phallus midventrally); apical region non-tubular, composed of a broad ventral scoop-like lobe, two pairs of lateral spines, dorsalmost being much the smaller, a paired, complex central structure whose parts are compressed mesally and has the ventral area produced slightly posteriad and bears a darkened, ribbon-like dorsal sclerotization, and a short, thin dorsal lobe whose apex is weakly bilobed; apical region partially covered by a membranous connection from tenth tergum.

Subgenus Rhyacophylax Müller

As discussed under “Genus Smicridea McLachlan” (and see Flint 1974a), the two subgenera are easily characterized in the adult stage, but not in their immature stages. The manner of separation of the veins R₂₊₃ and R₄₊₅ and the proximity of the the radiomedial system basally to the cubital system in the hindwing are sufficient for the recognition of the two subgenera. In addition, the males in Rhyacophylax lack the reticulate, internal sacs in the terminal abdominal segments that are present in the subgenus Smicridea. The males of Rhyacophylax lack the two preapical spurs on the hindlegs rather than having the full complement of four spurs as in the nominate subgenus.

The only species of subgenus Rhyacophylax known from the Chilean Subregion was placed in the magna species group (Flint 1974a). Now, with the synonymy of magna, this becomes the murina species group. The only other known species that shares the paired apicodorsal processes and lack of an apicoventral lobe on the phallus is S. (R.) appendiculata Flint, which is herein placed in the murina species group. These two species are mostly allopatric, with murina extending north to south along the Pacific Rim from Nicaragua to Chile, and appendiculata extending east and west from Brazil into Paraguay. An area of potential overlap exists along the eastern foothills of the Andes in Bolivia and northwestern Argentina.

This is probably the most widespread species in the genus. With the above synonymy established, it is known from Nicaragua south along the Andes to west central Argentina and Chile. I have specimens from Nicaragua, Costa Rica, Panama, Colombia, Venezuela, Ecuador, Peru, Bolivia, Argentina, and Chile (only those from the Chilean Subregion are listed in the “Material Examined,” below). There seem to be some rather stable size differences between populations. Specimens from the Province of Mendoza, Argentina, are the largest, the forewing length being 7–8 mm. Chilean specimens are rarely as large, and are commonly about a millimeter smaller. Those from Salta, Argentina, north to Central America are the smallest, with forewing lengths of ∼5 mm. The structure of the male genitalia remains very constant throughout its range, however. The pair of hornlike lobes apically from the top of the phallus are distinctive; the internal sclerites are rather simple and linear. The morphology of the male genitalia is very distinctive, being approached to some degree only by appendiculata. Both species have similar internal sclerites in the phallus, but the phallus of appendiculata is greatly enlarged apically, and its paired processes are longer and more slender than those of murina.

ADULT.—Length of forewing, 5.5–7 mm. Color grayish brown, body fuscous, appendages stramineous; forewing grayish brown, with darker marks over crossveins of chord, and a paler subterminal band (paler areas may have a yellowish cast). Eye of male in frontal aspect with diameter about half that of interocular distance. Fifth sternum with anterolateral processes 1½ times as long as sternum; lacking internal sacs.

Male Genitalia: Ninth segment with anterolateral margin produced upward and angulate. Tenth tergite in lateral aspect with tip barely upturned and produced, with ventrolateral margin heavily sclerotized, forming a distinct rim; in dorsal aspect with tip slightly produced and rounded, broad laterally. Clasper with basal segment long, parallel-sided; apical segment with tip pointed in dorsal aspect. Phallus tubular, with basal and apical sections meeting at about 90° apical section slightly enlarged apicad, tip with a pair of hooked processes directed dorsomesad; internal sclerites long, slender enlarged apically, with a ventral curved plate.

Female Genitalia: Internal plate in posterodorsal aspect with lateral arms parallel, anterior bridge transverse. Vagina with anterior bar bearing posterolateral processes about 1/3 as long as bar; centrally with a small, dark pore.

Systematic Relationships

The annulicornis and frequens species groups of Smicridea seem to be most closely related to each other with no other New World species of subgenus Smicridea remotely approaching them in appearance. Although some of the subgenus Rhyacophylax species, e.g., S. dithyra Flint or S. mesembrina (Navás), seem to show a condition whereby the apex of the phallus is closed by a pair of plates, these species are true members of the subgenus Rhyacophylax exhibiting all the diagnostic characteristics of the subgenus. However, these plates are differently formed and articulate from different points, thus I believe that they are analagous not homologous.

The Australian genera Smicrophylax and Asmicridea (Neboiss 1977, 1986), show great similarity in general appearance and especially in the apices of the phallus to the frequens species group of subgenus Smicridea. Both of the Australian genera do have the internal abdominal sacs and short lateral filaments from the fifth sternum as do the species of the subgenus Smicridea. I have cleared specimens of Smicrophylax ulmeri (Banks) and Smicridea frequens (Navás) and compared them side by side and find most differences noted by Neboiss (1977:68) are due to differences in interpretations of figures and words. The only real differences apparent between the two genera are a small, second spur on the foreleg and a much larger anal area of the hind wing in Smicrophylax; in all other areas they are virtually identical. The apicolateral phallic lobes of Smicrophylax are not concave mesally as they are in the frequens species group of the subgenus Smicridea, but convex; otherwise the genitalia are nearly identical. I believe that the Australian genus Smicrophylax and/or Asmicridea are most likely the sister group of the frequens species group, but probably the more pleisiomorphic of the two due to the presence of the second apical spur of the foreleg. Probably the annulicornis species group is derived from the frequens species group by a further development of the apicolateral plates of the phallus.

This suggests that the genus Smicridea is paraphyletic. However, because the resolution of this and other problems of phylogeny of Smicridea requires a thorough analysis of this and related genera, beyond the scope of this paper, I am leaving the basic nomenclatorial status as it currently exists. The relationships of the smilodon species group and the unplaced species are totally problematic. There is some possibility of a relationship between complicatissima and members of the nigripennis species group (Flint 1974a), but even this is questionable (see the section “Smicridea (Smicridea) complicatissima, new species”). The genitalia of these species are so different from anything known to me that no close relationship anywhere within the genus is apparent.

REQUIREMENTS FOR SMITHSONIAN SERIES PUBLICATION

Manuscripts intended for series publication receive substantive review (conducted by their originating Smithsonian museums or offices) and are submitted to the Smithsonian Institution Press with Form SI-36, which must show the approval of the appropriate authority designated by the sponsoring organizational unit. Requests for special treatment—use of color, foldouts, case-bound covers, etc.—require, on the same form, the added approval of the sponsoring authority.

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 manuscripts and art.

Copy must be prepared on typewriter or word processor, double-spaced, on one side of standard white bond paper (not erasable), 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 hierarchy of heads in the paper; also, foreword and/or preface, if appropriate.

First page of text should carry the title and author at the top of the page: second page should have only the author's name and professional mailing address, to be used as an unnumbered footnote on the first page of printed text.

Center heads of whatever level should be typed with initial caps of major words, with extra space above and below the head, but no other preparation (such as all caps or underline, except for the underline necessary for generic and specific epithets). 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 numbered table captions.

Formal tables (numbered, with captions, boxheads, stubs, rules) should be submitted as carefully typed, double-spaced copy separate from the text; they will be typeset unless otherwise requested. If camera-copy use is anticipated, do not draw rules on manuscript copy.

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

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

Text-reference system (author, year:page used within the text, with full citation in “Literature Cited” at the end of the text) must be used in place of bibliographic footnotes in all Contributions Series and is strongly recommended in the Studies Series: “(Jones, 1910:122)” or “…Jones (1910:122).” If bibliographic footnotes are required, use the short form (author, brief title, page) with the full citation in the bibliography.

Footnotes, when few in number, whether annotative or bibliographic, should be typed on separate sheets and inserted immediately after the text pages on which the references occur. Extensive notes must be gathered together and placed at the end of the text in a notes section.

Bibliography, depending upon use, is termed “Literature Cited,” “References,” or “Bibliography.” Spell out titles of books, articles, journals, and monographic series. For book and article titles use sentence-style capitalization according to the rules of the language employed (exception: capitalize all major words in English). For journal and series titles, capitalize the initial word and all subsequent words except articles, conjunctions, and prepositions. Transliterate languages that use a non-Roman alphabet according to the Library of Congress system. Underline (for italics) titles of journals and series and titles of books that are not part of a series. Use the parentheses/colon system for volume (number): pagination: “10(2):5–9.” For alignment and arrangement of elements, follow the format of recent publications in the series for which the manuscript is intended. Guidelines for preparing bibliography may be secured from Series Section, SI Press.

Legends for illustrations must be submitted at the end of the manuscript, with as many legends typed, double-spaced, to a page as convenient.

Illustrations must be submitted as original art (not copies) accompanying, but separate from, the manuscript. Guidelines for preparing art may be secured from Series Section, SI Press. All types of illustrations (photographs, line drawings, maps, etc.) may be intermixed throughout the printed text. They should be termed

Figures and should be numbered consecutively as they will appear in the monograph. If several illustrations are treated as components of a single composite figure, they should be designated by lowercase italic letters on the illustration; also, in the legend and in text references the italic letters (underlined in copy) should be used: “Figure 9b” Illustrations that are intended to follow the printed text may be termed Plates, and any components should be similarly lettered and referenced: “Plate 9b.” Keys to any symbols within an illustration should appear on the art rather than in the legend.

Some points of style: Do not use periods after such abbreviations as “mm, ft, USNM, NNE.” Spell out numbers “one” through “nine” in expository text, but use digits in all other cases if possible. Use of the metric system of measurement is preferable; where use of the English system is unavoidable, supply metric equivalents in parentheses. Use the decimal system for precise measurements and relationships, common fractions for approximations. Use day/month/year sequence for dates: “9 April 1976.” For months in tabular listings or data sections, use three-letter abbreviations with no periods: “Jan, Mar, Jun,” etc. Omit space between initials of a personal name: “J.B. Jones.”

Arrange and paginate sequentially every sheet of manuscript in the following order: (1) title page, (2) abstract, (3) contents, (4) foreword and/or preface, (5) text, (6) appendixes, (7) notes section, (8) glossary, (9) bibliography, (10) legends, (11) tables. Index copy may be submitted at page proof stage, but plans for an index should be indicated when manuscript is submitted.
