Eupyrgota (Asipyrgota) flaviseta (Aldrich) , comb. n. ( fig. 8 )

Aldrich, 1928: 2; Clausen et al., 1933: 13 ( Adapsilia ); Steyskal, 1977: 41 ( Peltodasia ) ( India).

M a t e r i a l. Type. Holotype ♀: India: Assam, Meghalaya: “ Shillong ”, “ C. R. Clausen ”, “ Adapsilia flaviseta Ald. ” [Aldrich handwriting], “Type No 40983 U.S.N.M. ” [red paper square] ( USNM). Paratypes: 4 ♀ (1 dissected): labels as in the holotype ( USNM) . Non-type: India: Assam, Meghalaya: Shillong, “ Adapsilia sp. , ortalid parasite on P.[opilia] cupricollis”, 1 Ơ (dissected) (L. B. Parker leg.) ( USNM) .

D i a g n o s i s. This species can be recognized from the combination of face with facial carina; epistoma low, 0.10–0.15× as high as antennal groove; parafacial yellow, in profile 1.6 times as wide as flagellomere 1 ( fig. 8 , 3 , 4 ); scutum blackish brown with yellow postpronotal lobe and scutellum; scutellum with at least two (often three) pairs of short and fine black setae; wing 9–9.5 mm long, uniformly brown on anterior two-thirds, pale gray along posterior margin, cells bm and bcu hyaline ( fig. 8 , 1 ); fore coxa unmodified; fore and mid trochanters without spinulose setulae; fore femur ( fig. 8 , 5 ) robust, 3.5× as long as wide, dark brown, except apicoventrally reddish yellow, without long setae, except thickened setae in ventro-apical rows black, spurious and short (0.15× as long as femur width); mid femur without femoral organ ( fig. 8 , 6 ); tibia brown, sometimes partly yellow; abdominal tergites blackish brown, syntergite 1 + 2 laterally yellow (in male with yellow belt at constricted part), tergites 5 and 6 posteriorly yellow ( fig. 8 , 10); surstyli as in fig. 8 , 7 ; glans of phallus as in fig. 8, 8 , 9; oviscape blackish brown with orange yellow apex ( fig. 8 , 10); its ventral area as in fig. 8 , 12; without hooks, but with desclerotized area and oval sucker inside of it; ventral receptacle as in other Pyrgotini; 3 sausage-like spermathecae, in examined female one spermathecal duct partly branched, with rudimentary additional spermatheca ( fig. 8 , 14).

R e m a r k s. This species is closely related to Eupyrgota (s. str.), as indicated by the presence of the nipple-like lobes on the prosternum (synapomorphy of the genus Eupyrgota ), robust habitus and the presence of more than 2 pairs of scutellar setae (possible synapomorphies at least with some species of Eupyrgota (s. str.)), and even could be considered a very specialized species inside of this lineage. It differs by lacking the paired sclerotized hooks on the oviscape (the presence of which is the key character and possible synapomorphy of Eupyrgota (s. str.) + Taeniomastix ). The lack of the hooks (absent in other Pyrgotini) can be either primary absence (then Asipyrgota is a sister group to Eupyrgota s. str. + Taeniomastix ) or secondary lack (then Asipyrgota is an in-group of Eupyrgota (s. str.), and the latter one is a paraphyletic group). The second hypothesis does not sound less probable. The hooks can be lost due to further transformation of the oviscape, possibly as the result of adaptation for oviposition into the abdomen of the m a l e host; by far, this is the only documented case of specialization of pyrgotids for parasitizing males.

Also, this is one of the few pyrgotids with described larvae ( Clausen et al., 1933).

All examined specimens were mounted and dried after storage in alcohol and have strongly shriveled wings, and this is why I do not illustrate its coloration and pattern, referring to the drawing in Clausen et al. (1933: fig. 7 ).

It was partly resulting from the study supported by the Belgian Federal Office for Scientific , Technical and Cultural Affairs Research Fellowship and conducted in the Royal Museum for Central Africa , Tervuren , Belgium in 2005–2006; most type specimens were photographed there. My thanks are due to Allen L. Norrbom (USDA SEL, Washington, D.C., U.S.A., material from USNM), David Notton (BMNH), Robert Copeland (NMKE), Neal Evenhuis (BBMH), and Bernhard Merz (Muséum d’histoire naturelle, Genève, material from NHMB), who kindly put at my disposal important material, both type and undetermined, or provided necessary data on the specimens deposited in collections under their care. I thank Allen L. Norrbom (Washington, D.C.) and Chris Raper (London) who reviewed this paper, for their criticism and valuable comments.
