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 Botany

Smithsonian Contributions to History and Technology

Smithsonian Contributions to the Marine Sciences

Smithsonian Contributions to Museum Conservation

Smithsonian Contributions to Paleobiology

Smithsonian Contributions to Zoology

In these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institutions throughout the world.

Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affiliation with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines. General requirements for manuscript preparation are on the inside back cover of printed volumes.

ABSTRACT

Adamski, David, Robert S. Copeland, Scott E. Miller, Paul D. N. Hebert, Karolyn Darrow, and Quentin Luke. A Review of African Blastobasinae (Lepidoptera: Gelechioidea: Coleophoridae), with New Taxa Reared from Native Fruits in Kenya. Smithsonian Contributions to Zoology, number 630, vi + 68 pages, 62 figures, 13 maps, 2 tables, 2010. — Twenty-five species of African Blastobasinae (Lepidoptera: Coleophoridae) are reviewed; 12 species are redescribed, and 13 species are described as new. Rearing of Lepidoptera ancillary to sampling efforts targeted for fruit flies (Diptera: Tephritidae) and their parasitoids was conducted in and near forested areas in coastal, central highland, and western highland habitats in Kenya. Reared moths were associated with fruits of 64 plant species in 34 families. Two new species, Blastobasis millicentae and Neoblastobasis perisella, were discovered in mixed original type series of species described by Meyrick and also reared from fruit. Eight new species, Blastobasis acirfa, B. aynekiella, B. chuka, B. elgonae, B. kenya, B. glauconotata, and Neoblastobasis ximeniaella, and N. wangithiae, are known only from specimens reared from fruit. One new species, Blastobasis catappaella, was reared from fruit and collected at black light. Finally, two new species, Neoblastobasis laikipiae and Blastobasis mpala, are known only from black light samples. DNA barcodes augmented the ability to discriminate between some closely related species within several genera. Male specimens of Blastobasis kenya, B. acirfa, and B. aynekiella and some associated female conspecifics, in particular, had distinctly different barcodes but were not initially diagnosed using standard morphological features. Subsequently, corroborative morphological features were found to support the DNA barcode data, and both data are discussed herein. Lectotypes are designated for Blastobasis arguta Meyrick, 1918; B. byrsodepta Meyrick, 1913; B. egens Meyrick, 1918; B. eridryas Meyrick, 1932; B. extensa Meyrick, 1918; B. indigesta Meyrick, 1931; B. industria Meyrick, 1913; and B. trachilista Meyrick, 1921. Zenodochium arguta Meyrick, 1918 is transferred to Calosima Dietz, 1910, new combination, and Tecmerium irroratella Walsingham, 1891 and Blastobasis extensa Meyrick, 1918 are transferred to Holcocera Clemens, 1863, new combinations. Neoblastobasis indigesta (Meyrick, 1931), revised status, is transferred to Blastobasis Zeller, 1855. Syndroma Meyrick is a junior synonym of Holcocera Clemens, 1863, and Syndroma lignyodes Meyrick, 1914 is transferred to Holcocera, new combination. The first African records for Holcocera, Calosima, and Neoblastobasis are reported. A key for all African Blastobasinae is included, together with photographs of the adults and illustrations of the male and female genitalia. Distribution maps are provided for all new species reared from fruits. All taxonomic decisions such as new species, lectotype designations, synonymies, and transfers are attributed to the senior author.

Keywords: Lepidoptera, Blastobasis, Calosima, Holcocera, Neoblastobasis, Africa, fruit, DNA barcodes, cytochrome c oxidase I mitochondrial gene.

INTRODUCTION

Collaboration among the International Centre of Insect Physiology and Ecology (ICIPE), the Smithsonian Institution’s National Museum of Natural History (USNM), the National Museums of Kenya (NMK), and the Department of Integrative Biology, University of Guelph, in understanding the Lepidoptera of Kenya has provided an opportunity to review the Blastobasinae (Coleophoridae) of Africa. From 1999 to 2004, Copeland directed an insect-rearing program from native fruit at sampling sites throughout Kenya. Much of the data from this study, which focused primarily on fruit flies (Tephritidae), has been published elsewhere (Copeland et al., 2002, 2004, 2005, 2006; De Meyer et al., 2002; White et al., 2003; Barr et al., 2006; Copeland and Wharton, 2006; De Meyer and Freidberg, 2006). Additionally, this study has provided the largest sample of reared Blastobasinae known from the African continent.

From 1998 to 2006, Miller (Miller, 2000) intensively sampled moths with black light at Mpala Research Centre (MRC) in central Kenya, thus providing a long-term view of the Blastobasinae at a single site. In order to provide a context for these samples, we examined the type material of all the previously described species of Blastobasinae from Africa. We used classical morphological characters and DNA barcodes (Hebert et al., 2003; Burns et al., 2007, 2008) to assess species limits. Although we are still accumulating samples of Blastobasinae from additional African localities, we are publishing this paper now to provide a taxonomic framework for further studies and to make the fruit-rearing data available for further analysis.

In the modern keys to moth families in Africa, only Delvare and Aberlenc (1989) and Holloway et al. (1987) included Blastobasinae; Janse (1932–1964), Pinhey (1975), and Scholtz and Holm (1985) did not. We follow Hodges (1998), who treated Blastobasidae sensu Meyrick (1894) as one of four subfamilies within Coleophoridae. Both Hodges (1998) and Adamski and Brown (1989) agree on the monophyly of the Blastobasinae. These small- to medium-sized moths can be identified by the following combination of characters: forewing with pterostigma between Sc and R_1, base of CuA_2 at or near right angle to cubitus, subcubital retinaculum present in female, spiniform setae on abdominal terga, aedeagal sclerite present, valva divided, and anellus setose.

This work was supported by USAID grant PCE-G-00-98-0048-00 (in collaboration with the International Centre of Insect Physiology and Ecology and its African Fruit Fly Initiative) and in part by USDA/CSREES/IFAFS grant 00-52103-9651, both awarded to R. A. Wharton, Texas A&M University.

MATERIALS AND METHODS

This study is based on approximately 300 specimens, including primary types of all named species, over 250 genitalic dissections, and 169 cytochrome c oxidase I (COI) sequences.

As part of biodiversity inventories undertaken in collaboration among MRC, ICIPE, USNM, and NMK (Miller, 2000; Miller and Lazell, 2003; Miller and Rogo, 2003), moths were collected at MRC by Scott Miller and Tina Kuklenski on 24 nights from May 1998 to December 1999 and on an additional 8 nights from 2000 through 2003. Moths were collected at mercury vapor and florescent black lights. The microlepidoptera were individually killed and spread in the field.

The MRC is a biological field station managed in collaboration with Kenya Wildlife Service, NMK, Princeton University, and the Smithsonian Institution. It is located in semiarid savanna on the Laikipia Plateau of central Kenya, west of Mount Kenya, 50 km north of the equator, and 50 km from Nanyuki town. MRC is at 1650 m elevation at 0.293°N and 36.899°E. Young et al. (1995, 1997), Keesing (1998, 2000), and the Mpala Wildlife Foundation (http://www.mpala.org) provide general descriptions of the environment. Annual mean rainfall at MRC is between 550 and 660 mm, but with substantial spatial and temporal heterogeneity (Berger, 1989). The vegetation is characteristic of semiarid African savannas, predominantly grassy savanna bushland, with patches of woodland and open grassland. Dominant trees include Acacia (Mimosaceae), Balanites (Balanitaceae), and Boscia (Capparaceae).

Although MRC has excellent facilities and is well situated in one of the most biologically interesting regions of Kenya, little invertebrate inventory work has been conducted there. Moreover, the Laikipia area has historically been ignored both by visiting biological expeditions and by local Kenyan residents, in part because it is outside of the famous wildlife parks. Early expeditions collected some insects in the Laikipia area, but they collected very few moths (e.g., von Höhnel, 1894; Chanler, 1896; Gregory, 1896; Rehn, 1936). On a purely historical note of interest, a nearby ranch was featured in the recent movie I Dreamed of Africa, based on the book by Kuki Gallmann (1991), and the natural history of another adjacent ranch has been recorded elegantly in popular essays by Grant (1995, 2001).

Rearing methods and sampling strategy for the native fruit-rearing program are provided by Copeland et al. (2002) and Copeland (2006). All fruits were collected from native plant species except for Passiflora mollissima (Kunth) L. H. Bailey (Passifloraceae). Ripe and unripe fruits were collected from plants and occasionally from the ground; samples showing noticeable rotting were discarded. Because of the rearing conditions and multiple techniques involved, the quality of adult moths varied. Thus, some specimens were not used in the analysis because of their poor condition.

The color standard for the description of the adult vestiture is from Kornerup and Wanscher (1978). Genitalia were dissected as described by Clarke (1941), except Mercurochrome and chlorazol black were used as stains. Pinned specimens and genital preparations were examined with dissecting and compound microscopes. All descriptions and redescriptions are based on adult morphology. The descriptions of the male and female genitalia, with respect to the orientation of a structure or structures relative to each other, were made as they are observed on the body proper and not how they may be illustrated from a permanent slide preparation. Measurements of wings were made using a calibrated ocular micrometer. Label data are given verbatim within quotations for all primary types and for selected paratypes. Other label data for reared specimens having “R.S. Copeland,” “ICIPE/USAID,” and “Restrictions Apply, NMK/ICIPE, Agreement # 5,” and the prefix of all eight-digit barcodes are omitted from the text. Genitalia slide numbers are in D. Adamski series unless noted otherwise. Acronyms for the depositories of specimens examined are as follows.

Sequences were produced at the University of Guelph. DNA was extracted from legs of adult specimens and amplified using a QIAGEN DNeasy Tissue Kit. Primers LepF1 and LepR1 (Hebert et al., 2004) were used to obtain a 658 base pair fragment of COI with a standard thermocycling regime (Hajibabaei et al., 2006). PCR products were sequenced subsequently on an ABI 3730 capillary sequencer. Sequences are available at the National Center for Biotechnology Information GenBank database (accession numbers GQ330121–GQ330289) and at the Barcode of Life Database (BOLD). Neighbor-joining (NJ) trees were generated from nucleotide sequences as implemented in BOLD (Ratnasingham and Hebert, 2007). Phylogenetic and molecular evolutionary analyses were conducted using Molecular Evolutionary Genetics Analysis (MEGA) version 4 (Tamura et al., 2007). While we recognize the limitations of NJ trees, they are an efficient means of analyzing and presenting DNA barcode data (Hajibabaei et al., 2006, 2007; DeSalle, 2007; Waugh et al., 2008). Our initial species identifications were based on morphology and were then tested against clustering based on DNA. We rechecked morphology when there were inconsistencies. DNA was especially helpful in associating conspecific males and females, as well as revealing some initial errors in morphological identifications. In only three cases (see “DNA Sequence Data” in “Discussion”) did morphology and DNA not agree on species identification, likely because of contamination. Because we expect to add DNA sequences for many species in the future, we are delaying more detailed analysis of sequences.

In this study, we regard all specimens within a type series that contains two or more specimens of a species described by E. Meyrick as syntypes. Although Meyrick indicated to Janse (in personal correspondence) in October 1909 and July 1912 that he considered the specimens studied and returned to Transvaal as “types” (see Janse, 1968), Meyrick did not specify a “type” in his original descriptions. Therefore, the “gentleman’s agreement” between Meyrick and Janse is not binding under the International Code of Zoological Nomenclature (ICZN), and it is our opinion that Janse erroneously labeled such specimens as “holotype.” Gozmány and Váry (1973) support this view, citing ICZN article 73(b), and they further indicate that Janse’s “holotype” designations are actually “lectotype” selections. We do not agree with Gozmány and Váry’s conclusion about “lectotype” selections by Janse, but we believe that their decision originated from their belief that all specimens within a type series that contains two or more specimens of a species described by E. Meyrick were indeed syntypes. If this is true, then their view supports our argument. We thus treat all specimens within Meyrick’s type series as having equal status, and our “lectotype” designations are based on the quality of the specimens rather than present deposition.

RESULTS

The taxon tree or phenogram (Figure 1) represents a total of 169 sequence samples for 15 species of Blastobasinae (Coleophoridae) reared from fruit or collected at black light in Kenya. Sequence data for Blastobasis kenya are represented by 57 samples and 1 “outlier” sequence of Blastobasis chuka (♂: 00196357, DA 5093).

Blastobasis elgonae is represented by two sequences (♂: 00196891, DA 5020 and ♀: 00196892, DA 5021) that cluster with one sample of B. glauconotata (♂: 00196387, DA 5019) and near one sample of B. glauconotata (♂: 00196367, DA 5106). Species assignments for these samples are resolved by examination of the male genitalia.

Four specimens from Shimba Hills diverge from the main Blastobasis acirfa cluster. Three of these (♂: 00196314,

A compressed subtree sequence data of Blastobasinae (Coleophoridae) taken from 169 samples among 15 species from Kenya based upon neighbor-joining analysis with Kimura 2-parameter model using pairwise deletion of gaps and or missing data. The analysis shows that 168 of the 659 sites exhibited variability. Subtrees are compressed into triangles with a vertical scale of 2 pixels per specimen; the horizontal scale corresponds to divergence. A single asterisk (*) indicates a sample of Blastobasis kenya with one “outlier” sample (USNM 00196357); ** indicates two “outlier” samples of Blastobasis glauconotata (USNM 00196387 and 00196367).

DA 5062; ♀: 00196381, DA 5121; ♀: 00196410) may represent an undescribed species, but we do not treat this in the taxonomic section because their identities are not clear because of the poor condition of the specimens. The fourth specimen in the divergent cluster (♂: 00196356, DA 5092) is identified as Blastobasis chuka and is treated below.

Two divergent samples (♀: 00196429 and ♀: 00196430) near Blastobasis kenya are treated as unassociated females and are not included in the taxonomic part of the text. Similarly, two divergent samples (♀: 00196893, DA 4361 and ♀: 00196405) near Blastobasis mpala are treated as unassociated females.

HOLCOCERINI Adamski & Brown, 1989

Holcocerini are the best-known blastobasine moths in the New World. This is likely because the tribe contains the largest species within the subfamily. Although the tribe contains over 160 described species, host associations for fewer than 13% of the total species are known. The Holcocerini can be distinguished by the following apomorphies: male aedeagus with a ring support at base and female having a telescopic ovipositor with three membranous subdivisions posterior to eighth segment, eighth sternum with anterior margin emarginated medially, ostium near anterior end of eighth sternum, and inception of ductus seminalis distant from ostium. In addition, there are several plesiomorphies found in most species of Holcocerini listed by Adamski and Brown (1989) that are helpful in differentiating them from species of Blastobasini.

Holcocera Clemens, 1863

TYPE SPECIES. Holcocera chalcofrontella Clemens, 1863, by subsequent designation (Walsingham, 1907).

The genus contains more species than all other genera within the Holcocerini worldwide. However, this disparity may be a result of disproportionate sampling. This genus is recognized by having a gnathos with the ventrolateral margin weakly fused with the tegumen, anellus multisetose, and a valva with the proximal flange not overlaid by microtrichiate membrane or sclerotized integumen.

Holcocera lignyodes (Meyrick, 1914), new combination

Syndroma lignyodes Meyrick, 1914b:271, type species of Syndroma Meyrick, 1914b. New synonym.

Syndroma lignyodes Meyrick, 1914b:271.—Clarke, 1963: 497.

HOLOTYPE. ♂, “M[ount] Mlanje, Nyasaland [Malawi], 20.I.1914, S.A. Neave, 1914-SSC”; “Syndroma lignyodes, Meyr., Type M603”; “Genotype, Syndroma Meyrick”; “♂ wing venation on slide 13.V.1949, JFGC 9480” [wing only, abdomen missing] [BMNH].

REMARKS. The presence of a notched first flagellomere of the antenna combined with holcocerine venational characteristics of the holotype justifies synonymy of the genus. The species is not included in the key because the pattern is worn and the abdomen is missing from the holotype.

Holcocera extensa (Meyrick, 1918), new combination

FIGURES 23, 42

Blastobasis extensa Meyrick, 1918:55.—Sinev, 2004:116.

DIAGNOSIS. Except for Holcocera lignyodes, H. extensa and H. irroratella are the only two species of Holcocera known from Africa. Although H. extensa is slightly larger and darker in appearance than H. irroratella, the female genitalia appear more reliable for differentiating the two species. H. extensa can be distinguished from H. irroratella by having a wider notch on the anterior margin of the eighth sternum, signum present within the corpus bursae, and the anterior part of the ductus bursae spinulate. Relationships of Holcocera extensa and H. irroratella are uncertain because males are not known and female genital characters tend to be conservative in nature throughout Blastobasinae.

REDESCRIPTION.

Head: Vertex and frontoclypeus with narrow pale gray scales. Outer surface of labial palpus grayish brown or gray intermixed with a few gray scales tipped with pale gray, white scales near subapical area of segment II and basal area of segment III, inner surface paler. Scape of antenna with scales grayish brown tipped with pale gray, flagellum grayish brown, gradually paler to apex. Proboscis with scales grayish brown tipped with pale gray.

Thorax: Tegula and mesonotum gray on anterior and posterior 1/3, pale gray on transverse median 1/3. Legs with scales grayish brown tipped with white with a white band near midfemur and apices of all segments and tarsomeres. Forewing (Figure 42) length 8.2–8.5 mm (n = 2), grayish brown intermixed with grayish brown scales tipped with pale gray and pale gray scales; two grayish brown streaks along radius and cubitus of cell; cell with a grayish brown spot on distal end near cubitus. Fringe grayish brown tipped with pale gray. Undersurface grayish brown. Hindwing: Pale grayish brown.

Abdomen: Male genitalia: Unknown. Female genitalia (Figure 23): Eighth sternum trapezoid, deeply emarginate medially on anterior end; antrum cuplike; inception of ductus seminalis on ductus bursae near anterior end of seventh sternum; posterior margin of seventh sternum straight; ductus bursae longer than ovipositor, slightly spiculate internally on anterior 2/3; corpus bursae ovoid, signum spiculate, ovoid.

LECTOTYPE. Designated herein, ♀, “[South Africa] Pret[oria], North, 12-2 [February]-1912, C.J. Swierstra”; “539”; “♀ Genitalia Slide by D. Adamski, No. 4489” [yellow label]; “Blastobasis extensa Meyr., Type No. 2551” [TMP]. A lectotype is designated in order to maintain stability of usage of the name of a taxon with congeners that look similar.

PARALECTOTYPE. ♀, “Pretoria, Transvaal, C.J. S[wierstra] 25-12 [December]-[19]16”; “Blastobasis extensa Meyr[ick], 1/1, E. Meyrick det., in Meyrick Coll[ection]”; “Meyrick Coll[ection], BM 1938-290”; “extensa Meyr[ick]” [abdomen missing] [BMNH].

REMARKS. Sinev (2004) treated two syntypes of Blastobasis extensa as blastobasine moths without examining the original type series and without designating a lectotype for the species. Therefore, the identifications for the two specimens that Sinev (2004) provided are unreliable.

Holcocera irroratella Walsingham, 1891, new combination

Blastobasis irroratella Walsingham, 1891:122, pl. VI, fig. 63.—Janse, 1917:192, check list.—Medler, 1980:307, check list.

Tecmerium irroratella: Sinev, 2004:117.

DIAGNOSIS. H. irroratella can be distinguished from H. extensa by having a narrower notch on the anterior margin of the eighth sternum, signum absent within the corpus bursae, and the anterior part of the ductus bursae absent of spinules. Relationships of Holcocera irroratella and H. extensa are uncertain because males are not known and female genital characters tend to be conservative in nature throughout Blastobasinae.

REDESCRIPTION.

Head: Vertex and frontoclypeus white intermixed with a few white scales tipped with brown and a few brown scales. Outer surface of labial palpus brown intermixed with a few white scales and white scales tipped with brown, inner surface white intermixed with a few brown scales; segment II short; scape of antenna white intermixed with a few brown scales, flagellum white. Proboscis white.

Thorax: Tegula and mesonotum white intermixed with white scales tipped with brown and a few brown scales. Legs brown intermixed with white scales tipped with brown, with a white band near midfemur and apices of all segments and tarsomeres. Forewing (Figure 48) length 6.6 mm (n = 1), white intermixed with white scales tipped with brown and some brown scales; median fascia and marginal spots absent; three distinct markings; brown streak near midcell, brown spot posterior midcell streak in area between CuP and margin, and large brown spot near crossvein extending to tornus. Fringe white tipped with brown. Undersurface brown. Hindwing pale brown, gradually darkening to apex.

Abdomen: Male genitalia: Unknown. Female genitalia (Figure 33): Eighth sternum deeply emarginated medially along anterior margin; posterior margin of seventh sternum straight; ductus bursae longer than ovipositor, gradually widening from ostium; inception of ductus seminalis anterior to posterior margin of seventh segment; corpus bursae spherical; signum absent.

HOLOTYPE. ♀, “Bathurst, GAMBIA, XI-1885, Carter, 1886, No. 881”; “Walsingham Collection, 1910-427”; “Blastobasis irroratella Wlsm. Tr. Ent. Soc. Lond. 1891. 122-3, Pl. VI-63, Type ♀, descr.”; “BM Genitalia Slide No. 30237” [BMNH].

REMARKS. Although Sinev (2004) examined the holotype female of Blastobasis irroratella, the absence of males makes generic assignment within the Holcocerini unreliable. However, the female features described above are more similar to Holcocera than Tecmerium.

Calosima Dietz, 1910

TYPE SPECIES. Calosima argyrosplendella Dietz, 1910, by original designation.

As with Holcocera, there are fewer Calosima recorded from the Old World than from the New World. Four species of Calosima are known in Thailand, and one species is known from Africa. Species of this genus have an aedeagus that is bulbous basally, a gnathos with a median ridge, and a juxta with an emarginate ventral margin.

Calosima arguta (Meyrick, 1918), new combination

FIGURES 2, 20, 51

Blastobasis arguta Meyrick, 1918:36.—Janse, 1917:192, check list.

Zenodochium arguta: Sinev, 2004:117.

DIAGNOSIS. Calosima arguta is most similar to C. albafaciella Adamski, 2002 from Thailand, but it differs from the latter species by having a wider gnathos, a narrower spinelike process of the lower part of the valva, and a longer and less curved aedeagus. In Africa, Calosima arguta is most similar to Holcocera extensa in sharing a spinulate anterior part of the ductus bursae and a platelike signum within the corpus bursae. However, because the male of H. extensa is not known, relationships between the two species are uncertain.

REDESCRIPTION.

Head: Vertex and frontoclypeus with scales brown or pale brown tipped with white. Outer and inner surfaces of labial palpus with scales brown tipped with white, apical area of segment II and all of segment III paler. Scape of antenna with scales brown or pale brown tipped with white, flagellum gray, wider and with more cilia in male; first flagellomere unmodified in male. Proboscis with scales brown or pale brown tipped with white.

Thorax: Tegula and mesonotum with scales brown or pale brown tipped with white. Leg scales brown tipped with white intermixed with dark brown scales tipped with white, with a pale brown band near midfemur and apices of all segments and tarsomeres. Forewing (Figure 51) length 6.7–7.0 mm (n = 3), scales brown or dark brown tipped with white, intermixed with pale brown scales, some tipped with white; basal and median fasciae brown or dark brown, complete, bisected by a wide, transverse, white band; apical 1/3 slightly paler than median fascia; large brown spot below distal end of cell near posterior margin. Fringe brown or pale brown tipped with white. Undersurface brown. Hindwing pale brown, slightly darkening to apex.

Abdomen: Male genitalia (Figure 2): Uncus setose, slightly elongate, ventrally keeled, ventral margin serrate; arms of gnathos projecting ventroanteriorly, fused medially, forming a widened band; vinculum narrow; juxta platelike; valva divided; upper part of valva widened basally, gradually narrowed from an abrupt, ventral emargination, produced into a digitate process, apex rounded; lower part of valva wide, subventral area reflexed to apicoventral angle, distally produced into an inwardly curved, acuminate process; aedeagus and sclerite of aedeagus broadly curved from base to apex; anellus with several microsetae. Female genitalia (Figure 20): Eighth sternum trapezoid shaped, deeply emarginate anteriorly; posterior margin of seventh sternum straight; ductus bursae about twice as long as ovipositor, narrow throughout length, with microspinules from inception of ductus seminalis to corpus bursae; inception of ductus seminalis posterior to seventh sternum; corpus bursae subovate; signum spiculate, on posterior end of corpus bursae.

LECTOTYPE. Designated herein, ♂, “Umkomaas [Natal, South Africa], 6-1[Jan][19]14, A.J.T. Janse”; “M-3831”; “Blastobasis arguta M[eyrick]”; “♂ Genitalia Slide by D. Adamski, No. 4628” [yellow label]; “Blastobasis arguta M[eyrick] Type No. 805” [TMP]. A lectotype is being designated in order to maintain stability of usage of the name.

PARALECTOTYPES (1 ♂, 1 ♀). ♂, “Syntype” [round, blue-bordered label]; “Umkomaas, Natal, A.J.T.J. 18-1[Jan][19]14”; “Blastobasis arguta Meyr[ick], 1/1, E.

Janse”; “M-3833”; “♀ Genitalia Slide by D. Adamski, No. 4629”; “Blastobasis arguta M[eyrick], Cotype No. 806” [TMP].

REMARKS. Sinev (2004) erroneously transferred Blastobasis arguta to Zenodochium. Adamski and Brown (1989) synonomized Zenodochium with Blastobasis, and H. arguta possesses holcocerine characters and not blastobasine characters (see Figures 2 and 20).

BLASTOBASINI Meyrick, 1894

On the basis of holdings in museum collections, Blastobasini are the more numerous of the two tribes of Blastobasinae. Many Old World species have unique male genital features, and the acknowledgment of these features may result in a proliferation of new genera by future workers. Species within Blastobasini may be recognized by having a forewing with a reduced tornus, male tegumen with tergal setae dorsolateral area, vinculum wide, juxta bandlike, anellus with stout setae or with macrosetae, gnathos with arms projecting ventrolaterally, anellus separate from juxta, female with telescopic ovipositor with four membranous divisions posterior to eighth segment, eighth tergum with a darkly pigmented median longitudinal streak, ostium slightly posterior to seventh sternum, and signum hornlike or spinelike.

Neoblastobasis Kuznetzov & Sinev, 1985

TYPE SPECIES. Blastobasis biceratala Park, 1984, by subsequent designation (Kuznetzov and Sinev, 1985).

Neoblastobasis contains about eight species that are found only in the Old World. Members of the genus can be recognized by having a large spinelike projection arising from the base of the lower part of the valva.

ETYMOLOGY. The species epithet, ximeniaella, is derived from the generic name of the plant from which the moth was first reared.

DISTRIBUTION. Neoblastobasis ximeniaella is restricted to coastal lowland habitats in southeastern Kenya.

HOST. Ximenia caffra Sond. (Olacaceae), Calophyllum inophyllum L. (Clusiaceae).

Blastobasis Zeller, 1855

TYPE SPECIES. Oecophora (Scythris) phycidella Zeller, 1839, by subsequent designation (Walsingham, 1907).

Blastobasis is closely related to Neoblastobasis, but in the absence of a phylogenetic analysis their relationship is uncertain. Species of Blastobasis can be recognized by having a dilated first flagellomere of the antenna with an inner surface bearing palmate scales and corpus bursae with a posterior lobe near inception of ductus bursae.

REMARKS. Blastobasis egens was described from a mixed series of 10 specimens, 3 of which are missing. Three female paralectotypes from New Hanover, Nkwaleni, and Umkomaas represent different species. The female from Umkomaas is believed to be conspecific with the male holotype, but the slide-mounted genitalia are in poor condition and are not illustrated. The paralectotype ♂ from Verulam is not conspecific with the holotype. In addition, a female specimen in the Transvaal Museum bearing the following label data is not believed to be part of the original type series and is not dissected: “Maritzburg, 1.2.[19]16, A.J.T. Janse”; “39/93”; “Blastobasis egens M[eyrick], Cotype No. 797”.

Sinev (2004) and Ghesquière (1940) made erroneous host associations between reared moth samples and several plant species, including Borassus aethiopum Mart. (Arecaceae), by not comparing dissected type material of Blastobasis egens with the reared specimens.

DIAGNOSIS. Blastobasis trachilista is similar in wing pattern to B. taricheuta, but it can be distinguished genitalically from the latter by having a narrower ostium, antrum and posterior part of ductus bursae, and an inner surface of the corpus bursae that is densely spinulate. Relationships between Blastobasis trachilista and B. taricheuta are uncertain because the males for both species are unknown.

Blastobasis determinata Meyrick, 1921:116.—Sinev, 2004:116.

DIAGNOSIS. Blastobasis determinata is similar to B. byrsodepta in wing pattern, but it can be distinguished from the latter by having a narrower ostium and the absence of a cuplike antrum. Relationships of Blastobasis determinata and B. byrsodepta are uncertain because the males for both species are unknown.

DIAGNOSIS. Blastobasis byrsodepta is similar to B. determinata in wing pattern, but it can be distinguished genitalically from the latter by having a wider ostium and a cuplike antrum of the ductus bursae. Relationships of both species are uncertain because the males for both species are unknown.

REMARKS. Meyrick described Blastobasis byrsodepta from five specimens, four from Barberton and Waterval and one from Pinetown (Natal). Although the number of specimens from each of the Barberton and Waterval localities is not known, two specimens from this series are apparently missing. The female paralectotype from Pinetown is not conspecific with B. byrsodepta and represents another species of Blastobasini. A male from Eala (Democratic Republic of Congo), with Meyrick’s syntypic labels [BM ♂ Genitalia Slide No. 30238], is not part of the original series from which B. byrsodepta was described and represents Neoblastobasis perisella n. sp.

Larvae of Blastobasis byrsodepta are reported to feed on stored ginger, Arachis hypogaea L. (Fabaceae) (Hargreaves, 1930), but this information was based on a misidentification of the moth species. Sinev (2004) and Ghesquière (1940) have erroneously made host associations between reared moth samples and two plant species, Borassus aethiopum Mart. (Arecaceae) and Zingiber officinale Roscoe (Zingiberaceae), by not comparing dissected type material of Blastobasis byrsodepta with the reared specimens.

DIAGNOSIS. Blastobasis industria is similar in wing pattern to many other African Blastobasis, but it can be distinguished from its congeners by having a very wide ostium and large, cuplike antrum of the ductus bursae. The relationship of Blastobasis industria with other Blastobasis is uncertain because the male is not known and female characters tend to be conservative in nature.

REDESCRIPTION.

Head: Vertex pale brown or scales pale grayish brown tipped with white. Outer surface of labial palpus brown with pale brown scales along apical margin of segment II; inner surface pale brown with a few brown scales. Scape of antenna pale brown, flagellum pale gray; first flagellomere of antenna in male dilated basally, forming a notch between itself and flagellomeres 2–4. Proboscis pale brown.

Thorax: Tegula and mesonotum pale brown or with scales grayish brown tipped with white. Legs brown intermixed with brown scales tipped with white with a white band near middle of all segments and apices of all segments and tarsomeres. Forewing (Figure 39) length 7.9–9.9 mm (n = 2), pale brown intermixed with brown scales tipped with white and brown scales (darker scales on distal 1/3); median fascia pale brown, incomplete; two brown spots within cell near crossvein, present or absent. Fringe pale brown. Undersurface brown. Hindwing pale brown.

REMARKS. Blastobasis industria was described from four specimens, two of which are missing. Larvae of B. industria are reported to feed on the beans of coffee, Coffea arabica L. (Rubiaceae) (LePelley, 1930; Rungs, 1979; Zhang, 1994), but the specimens likely were misidentified because the genitalia of the type specimens had not been examined.

DISCUSSION

HOST PLANT DISTRIBUTION OF REARED BLASTOBASINAE

The species of 11 blastobasines that were reared from fruits exhibited a wide range of hosts (Table 1). Among plant families, Sapotaceae was utilized most often, with Blastobasinae reared from 10 (50%) of the 20 species sampled. Other important host families were Rutaceae (5 hosts, 31% of the species sampled), Salicaceae (3 hosts, 23%), and Sapindaceae (4 hosts, 19%). Interestingly, fruits of Rubiaceae were of negligible importance, i.e., only one species, Oxyanthus goetzei ssp. keniensis, of the 106 species of Rubiaceae sampled produced blastobasines. In contrast, nonblastobasine microlepidoptera were reared from 38 (36%) Rubiaceae species, and Tephritidae (true fruit flies) were reared from 41 (39%).

Four (36%) of the 11 reared blastobasine species, Blastobasis catappaella, B. elgonae, B. millicentae, and Neoblastobasis wangithiae, came from a single host plant species, each of these representing a different plant family. Considering that we made 3847 collections of fruits from 927 plant taxa (most of these at the rank of species, with a few being subspecies or varieties) representing 117 families, these data provide strong evidence that monophagy is not uncommon in African blastobasines. Of the four monophagous species, only Neoblastobasis wangithiae did not share its host fruit (Pleiocarpa pycnantha) with other blastobasines. Of the two genera of Blastobasinae we reared from fruit, Neoblastobasis had a particularly limited host range, with N. wangithiae monophagous and both N. perisella and N. ximeniaella with only two hosts each, one of which was shared between them (Table 1).

The remaining five species, Blastobasis acirfa, B. aynekiella, B. chuka, B. glauconotata, and B. kenya were, to a greater or lesser extent, polyphagous, with B. kenya having the most hosts. This species was reared from fruits of 32 plant species, representing 22 families. Among frugivorous insects in Kenya, only the medfly, Ceratitis capitata (Wiedemann) (Tephritidae), and the false codling moth, Thaumatotibia leucotreta (Meyrick) (Tortricidae), exploited more fruit hosts than B. kenya. Through the course of the fruit survey we reared the medfly from 65 plant species representing 27 plant families, and we reared T. leucotreta from 85 species in 32 families (Copeland et al., 2009).

Among the polyphages, although there was considerable overlap among fruit hosts (Table 1), each Blastobasis species was reared from at least two fruit species that yielded no other Blastobasinae. Host exclusivity was most pronounced in Blastobasis glauconotata. It was the only blastobasine reared from 11 of its 17 (69%) host fruit species. During fruit sampling, an effort was made to avoid the collection of obviously rotting fruit. However, because the condition of fruit samples and the location of fruits collected (on the ground or on the tree) were not consistently documented, no definitive statement can be made about whether the blastobasine moths reared in this study were feeding on live plant tissue or slightly decaying plant tissue.

GEOGRAPHICAL DISTRIBUTION OF REARED BLASTOBASINAE

In Kenya, there are two major barriers to east-west migration of plants and animals. The xeric floor of the Gregory Rift Valley separates western Kenya from the central highlands. The valley was formed by intermittent volcanic and rifting activity that began ~15–12 MYA and has continued to near present. In the eastern part of the

country, a gently rising wide expanse of “dry scrub with trees” (Greenway, 1973) separates coastal habitats from the central highlands. Both barriers have very few plants with fleshy fruits, and these are represented primarily by species of Capparaceae, Cucurbitaceae, and Tiliaceae. In our survey, none of these plant families provided a single host plant for Blastobasinae. In contrast, the western and central highlands of Kenya support numerous areas of evergreen forests, as does the coast, providing an extensive resource for frugivorous insects. These forests have been connected and separated alternately, depending on climactic changes associated with glacial and interglacial periods, with the most recent period of connection occurring ~10 MYA (Lovett, 1993; Burgess et al., 1998). Since then, there has been a trend toward increasing dryness in East Africa, although coastal and western forests may have been united ~2.4 MYA (Burgess et al., 1998). Periodic forest connections and separations provide the conditions for allopatric speciation events, and the present richness of East African coastal forest endemics is thought to be due largely to them (Clarke, 2000). In all probability, they also affected the evolution and distribution of East African Blastobasinae.

In our survey, blastobasines were distributed throughout the sampling area (Table 2). Four species (Blastobasis millicentae, Neoblastobasis perisella, N. wangithiae, and N. ximeniaella) were restricted to coastal lowland habitats, and two (B. aynekiella and B. elgonae) were reared only from western Kenya, the former from several fruit species collected in Kakamega Forest, a Guineo-Congolean wet forest relict, and the latter from a single collection on Mount Elgon. Hosts of Blastobasis chuka and B. glauconotata were concentrated in the central highlands above 1600 m, though each was reared from collections made in western Kenya, and B. chuka was also reared from coastal fruits. Blastobasis catappaella was reared from fruits collected on the coast and was collected with black light in a xeric central highland (1650 m). Blastobasis acirfa and B. kenya had disjunct distributions. Both were reared from coastal and western sites but not from the intervening central highlands (B. kenya also was collected once in midaltitude eastern Kenya). This pattern is also often seen in the distribution of many plant species (and genera) with coastal populations represented in relict forests that were connected during wetter periods to central African equatorial forest (Clarke, 2000). Blastobasis elgonae and B. aynekiella were the only species restricted to western Kenya. It will be interesting to determine if this species also occurs in central African equatorial forest. Blastobasis kenya had the widest altitudinal distribution, between 5 and 2452 m above sea level.

DNA SEQUENCE DATA

Sequence data show three “outliers” in the compressed tree phenogram (Figure 1). An outlier sequence for one specimen of Blastobasis chuka (♂: 00196357, DA5093) occurs in sequence data for B. kenya, and two specimens of Blastobasis glauconotata (♂: 00196387, DA5019 and ♂: 00196367, DA 5106) almost match B. elgonae. All outlier samples were sequenced twice to verify the data. We suspect contamination. Species identification of the specimens representing the abovementioned “outlier samples” is based solely on the features of the genitalia, although mislabeling of genitalia slides is a possibility.

In addition, the phenogram shows that Blastobasis millicentae (♂: 00196942, DA4910) is linked with a node uniting four species of Neoblastobasis, suggesting that Blastobasis and Neoblastobasis may be congeneric. Interestingly, males of species in both genera possess palmate sex scales on the inner surface of the antennal dilation of the first flagellomere. Only through a broader phylogenetic analysis will this problem be resolved.

REQUIREMENTS FOR SMITHSONIAN SERIES PUBLICATION

ALL MANUSCRIPTS ARE REVIEWED FOR ADHERENCE TO THE SISP MANUSCRIPT PREPARATION AND STYLE GUIDE FOR AUTHORS (available on the “Submissions” page at www.scholarlypress.si.edu). Manuscripts not in compliance will be returned to the author. Manuscripts intended for publication in the Contributions Series are evaluated by a content review board and undergo substantive peer review. Accepted manuscripts are submitted for funding approval and scheduling to the Publications Oversight Board.

MINIMUM MANUSCRIPT LENGTH is thirty manuscript pages. If a manuscript is longer than average, an appropriate length will be determined during peer review and evaluation by the Content Review Board. Authors may be asked to edit manuscripts that are determined to be too long.

TEXT must be prepared in a recent version of Microsoft Word; use a Times font in 12 point for regular text; be double spaced; and have 1" margins. Each chapter/section must be saved in a separate file.

REQUIRED ELEMENTS are title page, abstract page, table of contents, main text, and reference section. See the SISP Manuscript Preparation and Style Guide for Authors for the order of all elements.

HEADINGS should be styled so different levels of headings are distinct from each other and so the organization of the manuscript is clear. Insert one line space above and one line space below all headings.

FRONT MATTER should include title page, abstract page, and table of contents. All other sections are optional. Abstracts must not exceed 300 words. Table of contents should include A-, B-, and C-level headings.

TABLES (numbered, with captions, stubs, rules) should be submitted in separate MS Word files; should include footnotes, if appropriate; should have rules only at top, bottom, and beneath column heads. Print outs of each table should accompany the manuscript to ensure correct layout of data. Tabulations within running text should not be numbered or formatted like formal tables, and should be included in the text of the manuscript.

FIGURE CAPTIONS should be provided in a separate MS Word file.

FIGURES (e.g., photographs, line art, maps) should be numbered sequentially (1, 2, 3, etc.) in the order called out; be placed throughout text, not at end of manuscript; have all components of composites lettered with lowercase letters and described in the caption; include a scale bar or scale description, if appropriate; include any legends in or on the figure rather than in a caption.

ART must not be embedded in the main text.

Figures must be original and submitted as individual TIFF or EPS files. Resolution for art files must be at least 300 dpi for grayscale and color images and at least 1200 dpi for line art. Electronic images should measure no more than 100% and no less than 75% of final size when published. JPG files will not be accepted. Color images significantly increase costs so should be included only if required. Funding for color art is subject to approval by SISP and the Publications Oversight Board.

TAXONOMIC KEYS in natural history papers should use the aligned-couplet form for zoology. 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.

SYNONOMY IN ZOOLOGY must use the short form (tax-on, author, year:page), with full reference at the end of the paper under “References.”

IN-TEXT REFERENCES should be used rather than bibliographic notes and should follow the author-date system in the following format: “(author last name, year)” or “. . . author (year)”; “(author, year:page used within the text)” or “. . . author (year:page).” A full citation should be included in a “References” section.

ENDNOTES are to be used in lieu of footnotes and should be keyed manually into a separate MS Word file, in a section titled “Notes”. Notes should not contain bibliographic information. Manually type superscript numerals in text and use full-sized numerals at the beginning of each note in the “Notes” section. SISP will determine the best placement of the notes section, either at the end of each chapter or at the end of the main text.

REFERENCES should be in alphabetical order, and in chronological order for same-author entries. Each reference should be cited at least once in main text. Complete bibliographic information must be included in all citations (e.g., author/editor, title, subtitle, edition, volume, issue, pages, figures). For books, place of publication and publisher are required. For journals, use the parentheses system for volume(number):pagination [e.g., “10(2):5–9”]. Do not use “et al.”; all authors/editors should be included in reference citations. In titles, capitalize first word, last word, first word after colon, and all other words except articles, conjunctions, and prepositions. Examples of the most common types of citations are provided in the SISP Manuscript Preparation and Author Style Guide.
