Oligosita debaiensis Yousuf & Shafee: Hayat, 2008: 9 –10, ♀, figures, key, taxonomy. Begum & Anis, 2013: 45, ♀, list. Begum & Anis, 2014: 9, checklist. Fatma et al., 2014: 116, ♀, Uttarakhand and Uttar Pradesh records.
Redescription. Female. Body length, 0.63 mm. Body yellowish brown; eye and ocelli dark. Antenna pale brown; clava brown. Mandible with tip dark reddish brown. Mesosoma with pronotum brown; mid lobe of mesoscutum and scutellum pale brown; axilla pale yellow; mid lobe of metanotum pale brown, side lobes brown. Fore wing hyaline with infuscation beneath stigmal vein and a slight infuscation beneath parastigmal vein. Legs with hind coxa and hind femur brown. Gaster with posterior margin of TIV −TVI pale brown.
Head, in frontal view, broader than high (90:72); frontovertex with transversely elongated striation, but from sides of eye down to near margin of eye with longitudinally elongate ridge-like reticulation; ocelli arranged in an acute triangle. Antenna (Fig. 14) with scape 3.12× as long as broad (25:8); pedicel 1.5−1.7× as long as broad; funicle segment slightly longer than broad (10:8); clava about 1.8−2.4× as long as broad; apical segment of clava with rod-like projection.
Mesosoma. Pronotal collar with 2 pairs of setae; mid lobe of mesoscutum about 1.75× as broad as long (49:28); scutellum about 1.95× as broad as long (41:21); mesophragma extending up to TIII; propodeum longer than metanotum (19:4). Fore wing (Fig. 15) about 3.3× as long as broad (176:53); marginal fringe 1.2× as long as wing width (53:44); hind wing 20.5× as long as broad (164:8); marginal fringe 5.62× as long as wing width (45:8).
Metasoma. 1.58× as long as mesosoma (124:78); ovipositor1.70−1.77× as long as hind tibia and 1.6−1.9× as long as mid tibia, originating from level of TI gaster and hidden.
Male. Unknown.
Type material examined. Holotype, ♀ (on 2 slides), labelled, “449 Oligosita debaiensis sp.n. M. Yousuf Aligarh, Debai 28.x.1985 ” and a ticket with ‘Holotype’ written in red ink (ZDAMU, HYM. CH.348). Paratypes: 1 ♀ out of 2 ♀ (on slide), labelled, “508 Oligosita debaiensis sp.n. M. Yousuf Aligarh, Debai 28.x.1985 ” and a ticket with ‘Paratype’ written in green ink (ZDAMU, HYM. CH.348).
Additional material examined. INDIA: KERALA: Ernakulam, Vallarpadam, 1♀, 11.i.2012, coll. F. R. Khan. UTTAR PRADESH: Pilibhit, Pakadia Naugonva, 1 ♀, 12.ix.2006, coll. F. R. Khan. (ZDAMU) Material determined and listed by Begum & Anis (2013) and Fatma et al. (2014) was also examined.
Distribution. India: Kerala; Uttarakhand; Uttar Pradesh.
Comments. The original description of this species was based on 2 females. The holotype is on two slides, one slide with one antenna, one fore wing and one hind wing under a large coverslip, and the rest of the body (antenna beyond scape detached and badly crushed) on another slide under a small coverslip. The paratype is on a slide with 2 females, bearing the same data as the holotype, with collection number ‘508’, but which one of these two specimens is the paratype is not indicated.
This species appears similar to O. hilaris (Perkins1910) based on the brief notes and figures given by Viggiani (1981), but can be separated from the latter in having the antennal funicle segment as long as broad or slightly longer than broad, and clava about 2× as long as broad. In O. hilaris the funicle segment is distinctly longer than broad, and the clava is about 4× as long as broad.
