Subgenus Asipyrgota V. Korneyev , subgen. n.

T y p e s p e c i e s: Adapsilia flaviseta Aldrich, 1928: 2 .

D i a g n o s i s. The type species in its robust body and widely brown wing and legs, as well as female aculeus and male genitalia structure agrees with Eupyrgota s. str. differing by the structure of the apico-ventral portion of the oviscape (a “sucker” instead of hooks); the only species can be recognized also from. See also remarks for E. (A.) flaviseta .

D e s c r i p t i o n. Moderately large, robust species; widely and uniformly darkened; scutellum with 3 pairs of setae; fore and mid trochanters of female without spiny or hooklike setulae; oviscape without ventral hooks, but with desclerotized U-shaped area and narrower oval sucker-like area inside, rimmed with narrow bare area ( fig. 8 , 11, 12). Male genitalia ( fig. 8 , 7 –9) similar to those in Eupyrgota (s. str.).
