Redescription. Female. Length, 0.62 mm. Body brown. Head with frontovertex pale yellow; eye dark. Antenna with scape pale brown; pedicel and flagellum brown. Mandible with tip honey brown. Mesosoma with pronotum dark brown; mesoscutum, scutellum and metanotum lightly washed with brown; side lobes of metanotum and propodeum dark brown. Fore wing hyaline. Legs with hind coxae dark brown; middle part of hind femur dark brown but apical part pale brown; tibiae and tarsi brown but last segment of tarsi dark brown. Gaster TIII −TVII with narrow brown cross-bands.
Head, in frontal view, broader than high; frontovertex with transversely elongated striations and with 9 prominent setae; eye height 2.75× as long as malar space (44:16). Antenna (Fig. 1) with scape 3.62× as long as broad (29:8); pedicel 2.3× as long as broad (21:9); funicle 1.5× as long as broad (12:8); clava 3.6× as long as broad (40:11).

Pronotal collar with 3 pair of setae; mid lobe of mesoscutum 1.2× as broad as long (42:35); scutellum 2× as broad as long (40:20); metanotum equal in length to propodeum (4:4); mesophragma extending up to TII of gaster. Fore wing (Fig. 2) 4× as long as broad (200:50); marginal fringe subequal in length to wing width (52:50); disc densely setose. Hind wing about 31.3× as long as broad (188:6); marginal fringe 7× as long as wing width (42:6).
Metasoma. Gaster longer than mesosoma (148:75); ovipositor 1.20−1.25× as long as hind tibia and 1.25× as long as mid tibia, originating from TIII.

Type material examined. Holotype, ♀ (on two slides), labelled, “M.Y.R.A. 616 Oligosita ___ sp.n. Phaphund Village Distt-Meerut 29.ix.1990 M. Yousuf” and another label added by Hayat “Female Oligosita angustipennis Yousuf & Shafee HOLOTYPE (Parts) det. M. Hayat, 2007” and “Female Oligosita angustipennis Yousuf & Shafee HOLOTYPE (Body) det. M. Hayat, 2007” (ZDAMU, HYM. CH.415).
Additional material examined. INDIA: KERALA: Ernakulam, Kozhencherry, 1 ♀, 12.i.2012, coll. F. R. Khan. UTTAR PRADESH: Aligarh, Begum Sultan Jahan, 1 ♀, 23.x.2013, coll. S. Begum (ZDAMU). Material determined and listed by Begum & Anis (2013) was also examined.
Distribution. India: Kerala (new record); Uttar Pradesh.
Comments. The original description of this species was based on a single female. The holotype is on two slides, one slide with one antenna and fore wing under a large coverslip, and the rest of the body (head partly damaged; mesosoma and metasoma somewhat crushed) on another slide under a small coverslip.
This species appears to be very similar to O. macrothoracica Lin (1994), but differs from the latter in having the fore wing with different setation (Fig. 2) and about 4× as long as broad, and the clava about 3.6× as long as broad. In O. macrothoracica the fore wing is 3× as long as broad and the clava 4.6× as long as broad.
