Eupyrgota angustifrons (Bezzi) , comb. n. ( fig. 3 )

Adapsila angustifrons Bezzi, 1914: 158 .

M a t e r i a l. Type. Holotype ♀: India: “ Near Bhowali, Kumaon , / 5,700 ft / A. D. Imms 1910 / 14 June at light ”, “ Adapsila / angustifrons /n. sp. / Type ♀” (pink paper label with Bezzi’s handwriting), “Type / 1914.331 [red bordered circle]”, “Holo / type [red bordered circle]”, “Holotype Adapsila angustifrons Bezzi verified J. E. Chainey 2002”, “BMNH # 252156”. Directly pinned ( BMNH). Non-type. China: “Darien, China ”, “DG Hall collection”, 07.1938, 1 ♀ (Weymann); Szechwan, Kuanshien, 1934, 2 Ơ, 2 ♀ (D. C. Graham) ( USNM).

D i a g n o s i s. This species can be recognized from the combination of face with facial carina; no ocellar setae; parafacial in profile twice as wide as flagellomere 1 ( fig. 3, 3–5 ), mesonotum and abdomen reddish yellow with a few brown or black spots or without them; scutellum with three pairs of long golden yellow setae; wing almost uniformly hyaline with yellow veins, without spots or bands ( fig. 3 , 6 ); fore coxa unmodified; fore and mid trochanters with spinulose brown setulae; fore femur without long setae, except 2 subbasal ventral setae, mid femur without femoral organ ( fig. 3 , 7 ); setae in ventroapical rows brown, spurious; abdominal sternites sparsely yellow setose; ventral hooks on oviscape strong; most setae brown to reddish yellow, setulae golden yellow. The presence of more than two scutellar setae and strong hooks on the oviscape supports its placement in Eupyrgota (s. str.).

R e m a r k s. This species possesses all the characters of Eupyrgota (s. str.), and I transfer it to the nominal subgenus. However, it shows apparently no essential differences from E. flavopilosa ( Hendel, 1914) and E. rufosetosa Chen, 1947 . Thorough comparison of existing material is needed to see if these nominal species are synonyms.
