FIGURES 28–30. Oligosita obliqua Fatma & Begum , female: 28, antenna, holotype; 29, fore wing, holotype; 30, mesosoma, holotype. Metasoma. 1.7× as long as mesosoma; ovipositor long, 2.9× as long as hind tibia (140:48) and 3.0× as long as mid tibia (140:46) and originating from base, and exserted. Male . Unknown. Material examined. Holotype , ♀ (on slide), labelled, “ INDIA : UTTARAKHAND: DEHRADUN, 03.xi.2009 Coll. F.R. KHAN ” ( ZDAMU , Registration No. HYM. CH .701). Distribution . India : Uttarakhand. Comments . The original description of this species was based on one female. The holotype is on one slide under 3 coverslips. This species appears similar to O. curvialata Lin (1994) , but differs from the latter in having the fore wing 5.1× as long as broad, longest marginal fringe 2× as long as wing width, antennal clava broad, about 3.6×as long as broad (32:9), C1 shortest, C2 and C3 subequal in length (11:12), and ovipositor 2.91× as long as hind tibia (140:48). In O. curvialata the fore wing is 4.2× as long as broad, longest marginal fringe 1.3× as long as wing width, antennal clava narrow, about 4.7× as long as broad, C1 longer than C2, C3 longest, and ovipositor 2.67× as long as hind tibia.
