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 Paleobiology

Smithsonian Contributions to Zoology

Smithsonian Studies in Air and Space

Smithsonian Studies in History and Technology

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

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

Introduction

Following the completion of a review of Sesioidea classification (Heppner and Duckworth, 1981), specimens of the immature stages of the genus Millieria Ragonot became available and were found to have many characters anomalous to other Choreutidae known thus far, indicating that a new subfamily would be needed. Among these characters the most notable are double rows of spines on the abdominal tergites of the pupa (being only single rows in other Choreutidae) and the bisetose L-group on the larval prothorax (being trisetose in other Choreutidae). The adults of Millieria dolosana (Herrich-Schäffer), the only known member of this European genus, have most characters typical of other choreutids. Their biology, contrarily, is very distinct from other choreutids, being the only known leaf miners in the family. In addition, a new genus and new species from Florida was found to have anomalous immature characters, as well, yet with some conformity to Millieria. Further investigation also revealed affinities between Millieria, the Florida genus, and an undescribed moth from central Chile, which previously had been too unusual to relate to other known Choreutidae.

All these taxa are described below and associated within the new subfamily, Millieriinae. The immature characters of the subfamily, while divergent from other Choreutidae, demonstrate the characters showing the affinities of Choreutidae with Sesiidae and Brachodidae, the other two sesioid families. Thus, the Millieriinae are somewhat of a missing link between other Choreutidae and the remainder of the Sesioidea, further confirming their fundamental relationships.

FIGURE 1.—Hypothetical phylogeny of Millieriinae genera in relation to other Choreutidae and Sesioidea (characters listed in Table 1; characters 10–14 are charted for all three families to note some symplesiomorphies.).

REMARKS.—The most significant aspect of this group involves their bridging the gap between Brachodidae and Sesiidae, the other two families of Sesioidea, and the remaining Choreutidae genera. The larvae and pupae of choreutids until now were different from other Sesioidea in some characters, notably the single spine rows on the dorsum of the pupal abdominal segments. The bisetose pre-spiracular L-group setae of the larval prothorax, which is the same as in known Brachodidae (Sagalassa), also show that the higher choreutids have developed from some ancestral Brachodidae (other Choreutidae are trisetose). In Brachodidae and Millieriinae, the prothoracic bisetose L-group condition becomes the normal trisetose condition on the meso- and metathorax, like other Sesioidea.

The new genus from Florida (Phormoestes) shows similarities to Millieria in the larva, while the pupa has the basic characteristics of the new subfamily. The pupa diverges, however, by its unusual diffused spine rows. This new genus is certainly a tropical element. Immature characters are not known for the new genus (Nyx) from Chile. Additional characters that differentiate Millieriinae from other choreutids include the short or reduced larval prolegs; the closer prothoracic SD1 and SD2 setae (Millieria), which is similar to the condition in Sesiidae; and the D2 setae on abdominal segment 8. The D2 setae are equally close to D1 or closer than D1 setae; this relationship is the same in species of Brachodidae and Sesiidae, but the opposite of other Choreutidae. Although adults of Millieria appear like typical choreutids, larval characters like the long frontoclypeus and the reduced prolegs show differences from typical choreutids. In the new Florida genus the opposite is true. Thus from various larval characters and from the double rows of spines of the pupa, the Millieriinae very interestingly demonstrate the evolutionary connection between Choreutidae and Brachodidae. The Sesiidae probably are a separate offshoot from ancestral Brachodidae. Table 1 summarizes these and other characters to show a hypothetical phylogeny for Millieriinae and Sesioidea (Figure 1).

FIGURE 2.—Distribution of Millieriinae taxa (circle = Millieria; square = Nyx; triangle = Phormoestes).

The Millieriinae currently contain only three genera, each monotypic, distributed in a very disjunct pattern (Figure 2): one genus in Europe, one in Florida, and one in central Chile. Although the three genera are related, the distributional pattern leads one to conclude that other species, if not genera, remain to be discovered. The two New World genera both have hosts among the monocots, while the Millieria host is a dicot plant.

The Millieriinae conform to certain basic characteristics of Choreutidae (small, usually l-segmented maxillary palpi; prominent ocelli; scaled haustellum; a forewing pterostigma; tortricoid abdominal apodemes; pupal dorsal spines), which distinguish the family from groups having a superficial resemblance in Gelechioidea, notably some Oecophoridae. Among the characters just noted, except for the scaled haustellum and the pterostigma, Oecophoridae have each character state the opposite of what is found among Choreutidae (Heppner, 1977:126). (Very rarely do some Gelechioidea have what appears to be a tortricoid abdominal apodeme arrangement.)

Pupation in a round lentil-like case of leaf material in mine on leaf surface (Figure 37); pupa protruded at adult eclosion.

REMARKS.—Millieria has always been viewed as a strange genus among the choreutid moths, primarily because of the unusual biology of its only included species, M. dolosana. As noted under the subfamily discussion, now that this genus has been found related to two unusual New World genera, its place in the phylogeny of the Choreutidae is more understandable. Previously it had only been thought somewhat related to Anthophila (Heppner and Duckworth, 1981:47) or Tebenna (Diakonoff, in press).

This European genus is morphologically distant from the New World genera of Millieriinae, yet relationships are evident in adult wing venation and larval chaetotaxy. The simple (i.e., distinct spine rows, as in Sesiidae) dorsal spines of the pupa and the overall facies of the adult in their resemblance to other Choreutidae indicate that this genus is less derived from some ancestor than are two New World genera, which appear much more advanced.

The larva of Millieria is most unusual for its head morphology, being very similar, both in head shape and the extent of the frontoclypeus, to larvae of leaf mining families like Gracillariidae. The reduction of the prolegs also conforms to this overall appearance of a gracillariid-like larva, apparently being due to the similar feeding habits of the larvae.

The pupa, as noted before, is striking in its similarity to pupae of Brachodidae and Sesiidae, with the two distinct rows of dorsal spines of the abdominal segments.

HOST.—Aristolochia clematitis Linnaeus and Aristolochia pistolochia Linnaeus (Aristolochiaceae) (Hering, 1957:114).

BIOLOGY.—The larvae are gregarious leaf miners of Aristolochia and make irregular blotch-like mines (Figure 37) on the dorsal surface of the leaves, with several larvae occupying one leaf mine. This larval behavior and biology is unique in the family as far as is known, although communal larvae are known in the hollow-stemmed host plants of Tebenna carduiella (Kearfott) from the United States. Except for the other Millieriinae, typical Choreutidae are leaf skeletonizers.

Pupation is within a lentil-shaped pupal case formed within the leaf mine. Millière (1856:39) gave the first description of the biology of this species. The biology or rearing record has also been noted by Hartmann (1880:54), Hering (1927:34, 1957:114), Spuler (1910:298), and Toll (1938:164). The species is bivoltine in Poland (Toll, 1938), but collection records do not show any clear generations further south, only overlapping generations.

REMARKS.—Adults of M. dolosana cannot be mistaken for any other choreutid from Europe. Of the choreutid genus Caloreas from the New World, there are only a few species that also have white hindwings. The genitalia are very distinct in Millieriinae, especially in the unique scaphium of the male. In the female the signum easily distinguishes the species. The species is very widespread in Europe and appears to be relatively common wherever the host plant occurs.

LARVA (Figures 42–50).—Head (Figures 43–44) hypognathous; frontoclypeus only ½ distance to epicranial notch. Stemmata in rectangular semicircle. Proleg short; crochets (Figure 45) in circle, biordinal. Prothorax with sclerotized dorsal shield; L-group bisetose on one pinaculum (trisetose on meso- and metathorax); SD2 distant to SD1; SV setae approximate on one pinaculum. Meso- and metathorax with L1 close to L2 and distant from L3; SD2 on mesothorax greatly elongated.

PUPA (Figures 51–53).—Head with blunt projection on front. Maxillary palpus prominent. Legs free at wing tips. Dorsal abdominal spines present in wide diffuse band composed of two rows on tergites A2–7 in males (A2–6 in females), with the two rows becoming more distinct progressively posteriorly; single band of spines on tergites A8–9. Abdominal segments A3–7 in males (A3–6 in females) movable. Cremaster not evident except for somewhat hook-tipped setae on posterior end (Figure 53). Pupation in a hollow flower pod (Figure 54) with flap-like opening; attached to ventral side of leaf of host along leaflet midrib; pupa extruded at adult eclosion.

REMARKS.—Phormoestes is a very curious genus of Choreutidae. At first view it appears more like an oecophorid, yet it does not conform morphologically to this family. The wing venation, head morphology, and immature characters conform to the basic characteristics of Choreutidae. This genus is very different from Millieria in many characters yet shows basic similarities. The wing venation of the two genera are quite similar, the only major difference being the stalked M_3 and CuA_1 veins of the hindwing of Millieria, which is also unusual for the family as a whole. The head morphology of Phormoestes shows considerable derivation from the Millieria line, with less lateral compound eyes and labial palpi having more subequal segments and a reduced ventral scale tuft. The maxillary palpi appear to be 1-segmented, but the base may be another segment almost fused to the galaea. The morphology of the caudal end of the head shows more similarities to the new genus from Chile, especially in the prominence of the occipital condyli, which are not evident in Millieria. The genitalia of P. palmettovora, especially the male genitalia, are very distinctive, notably the tubular tegumen-vinculum and the strong uncus and gnathos.

The larva of Phormoestes is very similar to that of Millieria in basic characters. The biordinal crochets of the prolegs are most distinctive for Phormoestes, being uniordinal in all other Choreutidae. However, in other characters the larvae are more similar to other choreutids than are larvae of Millieria.

The pupa is also very distinctive and appears considerably derived from the more primitive state found in Millieria.

ETYMOLOGY.—The name Phormoestes is Greek for “basket dweller,” referring to the pupal case.

DISTRIBUTION (Figure 2).—Known only from Florida.

FLIGHT PERIOD.—March to May.

HOST.—Sabal palmetto (Walter) Loddiges (Palmae).

BIOLOGY.—Alvah Peterson was the first to rear this species and in doing so to discover the species. Unfortunately he did not publish anything on the biology. The larvae are found boring within the minute flower pods of the sabal palm inflorescence. Thus, this feeding behavior would appear to enforce a reduced period of adult activity per year, since the palms only bloom from spring to early summer. Indeed the collection records for adults are only from March to early May. After sufficient feeding, the larvae apparently take one of the hollowed out flower pods and form a pupal case, having a flap on the distal end, and transport this case to the ventral side of one of the large palm leaves. The pupal case (Figure 54) is attached to the midrib of one of the many leaflets of the palm leaf. Although thus far not confirmed, it would appear that larvae (or pupae) overwinter in the pupal case and adults of the first generation emerge the following March, when the palms are again producing inflorescences. It is conceivable that over the period from March until May and possibly to early July, there could be two, perhaps even three generations, but this remains uncertain. However, freshly emerged adults have been taken in each of the three months from March until May.

REMARKS.—This is the only known species of Phormoestes. Although the host plant and the general appearance of the moths indicates a tropical element of the Florida fauna, no related moths are known in the neotropics except for the new species from Chile, which is a very isolated south temperate species. The genital morphology, in addition to wing coloration, will easily distinguish the species from the Chilean species or any other moth from Florida. The only diurnal Florida moth that has a remote resemblance to P. palmettovora is the unrelated Neomachlotica spiraea Heppner of the family Glyphipterigidae, but close examination will easily distinguish the two.

Nyx, new genus

TYPE-SPECIES.—Nyx puyaphaga, new species.

ADULT.—Small moths, 3.8–5.0 mm forewing length.

Head (Figure 7): Vertex and frons vestiture smooth. Labial palpus short, slightly upcurved, relatively smooth scaled; segments subequal. Haustellum scaled at base. Maxillary palpus (Figure 8) minute, 1-segmented with long distal seta. Pilifer large. Eye moderate. Ocellus small. Antenna filiform. Caudal end of head (Figure 11) with tentorial bridge subtending large ovate upper opening from small subquadrate lower opening, with prominent occipital condyli.

Thorax: Normal. Legs with normal tibial spurs.

Forewing (Figure 14): Shape elongate, with somewhat pointed apex; evenly rounded tornal and anal margins. Pterostigma not very prominent, small, from Sc to R_3. Sc to wing length. R_1 to ¾ from base; R_2 separate; R_3 stalked with R_4 directly at their base; R_5 free, to apex. Chorda absent. Cell ¾ wing length, with vestigial median vein present. Median veins evenly spaced. CuA_1 and CuA_2 divergent; CuA_2 from near end of cell. CuP present at tornal margin. A1+2 with moderate basal fork; A_3 vestigial.

Hindwing: Shape elongate, with pointed apex and slight convexity along anal margin. Sc to ¾ from base. Radius to near apex. Cell to wing length, with vestigial vein slightly evident. M_1 to apex, near to Rs at end of cell; M_1 to M_3 evenly spaced. CuA_1 and CuA_2 divergent, with CuA_2 from near end of cell. CuP present at tornal margin. A1+2 fork ½ length of vein, A_3 almost subequal to A1+2 in length; A_4 short.

Abdomen: Normal. Coremata present beneath 8th sternite and with opening for eversion on intersegmental membrane between sternites 7 and 8.

Male Genitalia: Tegumen fused to vinculum. Saccus vestigial. Uncus present. Gnathos a blunt point with a recurved surface and strong lateral arms. Socius absent. Valva simple. Anellus a projected half-tube supporting aedeagus, without lateral process. Aedeagus very long, narrow, with apical denticious spines. Cornutus absent.

Female Genitalia: Ovipositor very long, with strongly sclerotized and sharp papilla analis. Apophyses very long and stout. Ostium simple, without a sterigma; 8th tergite with strong bladelike posterior projection. Ductus bursae membranous. Corpus bursae simple. Signum of small spines at ductus juncture with bursa.

Larva and pupa unknown.

REMARKS.—Nyx appears to be the most specialized member of the Millieriinae, with the modified ovipositor of the female being most derived and apparently designed to penetrate the host plant for egg deposition. The head and genital morphology of the genus point to a close relationship to Phormoestes, while the reduced maxillary palpus and loss of the chorda show a derived state. This is the first known choreutid genus with abdominal coremata.

ETYMOLOGY.—The generic name Nyx is derived from Greek for “puncture,” referring to the sharp ovipositor of the type-species females.

TYPE.—Holotype , USNM 100234.

TYPE-LOCALITY.—Chile: Angol, Malleco Prov., 5 Dec 1927, D.S. Bullock, ex Puya alpestris, USNM slide 77908.

PARATYPES (9 , 21 ).—Chile: Malleco Prov., Angol, 7 Nov 1928 (5 , 16 ), 14 Nov 1929 (, ), 16 Nov 1929 (2 , ), 5 Dec 1927 (, ), 10 Dec 1928 (), 17 Dec 1927 (), D.S. Bullock, ex Puya alpestris, USNM.

DISTRIBUTION (Figure 2).—Known only from central Chile.

FLIGHT PERIOD.—November to December.

HOST.—Puya alpestris (Poeppig) Gay (Bromeliaceae).

BIOLOGY.—The species was reared by D.S. Bullock in Chile, who thus obtained the only known specimens. Unfortunately, associated pupal shells and possibly larval specimens have become misplaced over the years and could not be located for this study. The female genitalia clearly show that the eggs must be inserted into the host plant, since the ovipositor is extremely stout and sharply pointed. It is not known into which part of the plant the egg is inserted or on what part the larva actually feeds. The host plant is one of the large yucca-like Chilean bromeliads.

REMARKS.—This species is very distinctive in external appearance and in genital characters. No known moth from Chile has any resemblance to it. The distribution of the host plant would also indicate that N. puyaphaga should not be found outside of Chile and the southern Andes Mountains. As noted in the description, one female paratype has dark hindwings; none of the males show such melanism. Chile has numerous species of Puya, as well as related bromeliads; thus it is possible that there are other members of the genus yet to be found on other species of bromeliads in this area of South America, which is relatively uncollected for microlepidoptera.

REQUIREMENTS FOR SMITHSONIAN SERIES PUBLICATION

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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