Oligosita doonensis Begum & Anis, 2015: 6907 –6909, ♀, India, Uttarakhand, Udaibagh (ZDAMU, examined). (Paratype from Uttar Pradesh examined.)

Redescription. Female. Length, mesosoma + metasoma, 0.55mm. Body brown; eye dark. Antenna pale yellow except clava pale brown. Mandible with tip honey brown. Mid lobe of mesoscutum pale brown; scutellum medially pale yellow, side lobes pale brown; metanotum pale yellow; propodeum medially pale brown, side lobes brown. Fore wing hyaline, with infuscation beneath stigmal vein and slight infuscation at basal part of fore wing; hind wing hyaline. Legs with coxae dark brown, femora pale brown, tibiae and tarsal segment of legs pale yellow. Gaster with dark brown cross bands.

Head. Antenna ( Fig. 17 ) thin and long with scape 3.11× as long as broad (28:9); funicle 1.1× as long as broad as and slightly shorter than first segment of clava (9:10); clava ( Fig. 17 ) about 6.1× as long as broad (55:9); lengths of C1, 10; C2, 18; C3 slender and longest, and with long hook-like bristle.

Mesosoma. Mesoscutum and scutellum with cellular sculpture; mesoscutum without setae; scutellum with 1+1 setae; mid lobe of mesoscutum 1.2×as broad as long (41:33); scutellum 1.75× as broad as long (35:20); propodeum 1.75× as long as metanotum (7:4); mesophragma extending up to TII of gaster. Fore wing ( Fig.18 ) incised at apex of retinaculum, 3.91× as long as broad (176:45); marginal fringe about 1.4× as long as wing width (65:45); hind wing about 25.3× as long as broad (152:6); marginal fringe 7.83× as long as wing width (47:6).

Metasoma. Ovipositor about 1.2× as long as hind tibia (80:65) and 1.25× as long as mid tibia (80:64), originating from TIII of gaster, and slightly exserted at apex

Male. Unknown.

Type material examined. Holotype, ♀ (on slide), labelled, “ INDIA: Ukd [UTTARAKHAND]: Dehradun Udaibagh 03.xi.2009 Coll. F.R. Khan” ( ZDAMU, HYM. CH.696).

Paratype: 1 ♀ (on slide), labelled, “ INDIA: UTTAR PRADESH: Aligarh Dhorau 7.iii.2009 Coll.: F.R. Khan” ( ZDAMU, HYM. CH. 696).

Distribution. India: Uttarakhand; Uttar Pradesh.

Comments. The original description of this species was based on two females. The holotype is on one slide under 3 coverslips. The paratype is also on one slide under 3 coverslips.

This species appears to be very similar to O. curvialata Lin (1994) in having the fore wing incised at the apex of the retinaculum, but differs from the latter as follows: funicle about 1.1× as long as broad, C2 longer than C1 ( Fig. 17 ), and ovipositor 1.2× as long as hind tibia. In O. curvialata the funicle is long and cylindrical, about 2.2× as long as broad, C1 longer than C2, C2 the shortest segment, and ovipositor 2.67× as long as hind tibia.
