Eutrichosomella

Key to Indian species of Eutrichosomella (females)

1. Antennal scape more or less cylindrical, at least 4× as long as broad; at most F1 transverse and F1 and F2 combined longer than F3 (Fig. 1); antenna yellow to white; fore wing infuscated below marginal vein, hyaline below submarginal vein and apex; fore wing with postmarginal vein absent (Figs 7, 12); scutellum with anterior pair of scutellar setae located in posterior half (Fig. 4).............................................................................................2

- Antennal scape slightly flattened with ventral margin broadly convex, slightly more than 3× as long as broad; F1 and F2 transverse, both combined shorter than F3 (Manickavasagam & Menakadevi 2012: fig. 3); antenna dark brown, with a subapical band on scape, and upper margins of pedicel and F3, white, and clava white with a large brown patch in basal third; fore wing infuscate except base below submarginal vein, a large suboval spot in the median infuscate area, a transverse, nearly straight band adjacent to distal veins, and the apex narrowly, hyaline (Manickavasagam & Menakadevi 2012: fig. 6); fore wing with postmarginal vein present, about three-fourths length of stigmal vein (Fig. 15); scutellum with anterior pair of scutellar setae located in anterior third (Fig. 13). (Body largely brown to dark brown, gaster with TI white.)........................................................................................ E. keralaensis Manickavasagam & Menakadevi

2. Antenna with funicle segments all longer than broad, but F1 shorter than F2, F3 1.57× as long as F2 (Singh & Srinivasa 2010: fig. 4); median length of propodeum 1.46× as long as median length of metanotum (Fig. 11); fore wing with width of the apical hyaline area broad, about 0.55× width of infuscate area (Singh & Srinivasa 2010: fig. 8); gaster brown, with TI except a brown band across base, and TII, except posterior margin, white.......................................... E. indica Singh

- Antenna with F1 slightly broader than long, shorter than F2, F3 1.18× as long as F2 (Fig. 1); median length of propodeum 3× median length of metanotum (Fig. 5); fore wing with width of the apical hyaline area about 0.12× width of infuscate area (Fig. 6); gaster dark brown, with TI medially in about anterior half white..........................
