Description
Female (habitus: Figs 144, 153)
COLOUR. Head (Figs 145–146) black. Mandibles reddish-yellow, teeth darker. Antenna (Fig. 148) with scape and pedicel reddish-yellow, pedicel sometimes darker dorsally; flagellum brown, gradually becoming darker towards clava. Mesosoma (Figs 149–151) dorsally reddish-brown, occasionally dark brown. Mesepisternum and sometimes mesepimeron brown to dark brown. Legs reddish-yellow. Fore wing evenly and slightly to moderately infuscate; setation brown (Figs 152, 154). Hind wing hyaline. Metasoma with petiole reddish-brown (Fig. 151); gaster (Fig. 144) dorsally dark brown to black, ventrally pale. Body setation pale except for several large, symmetrically arranged dark brown setae.
BODY LENGTH. 1.6–2.4 mm.
HEAD. Clypeus virtually smooth; apical margin slightly produced (Fig. 147). Lower face coriaceous to shallowly reticulate, piliferous punctures not distinct. Upper face including vertex reticulate (Fig. 146). Scrobes deep, reticulate; parascrobal region with elongate cells (Fig. 145). Occiput coriaceousalutaceous; margin sharply defined (Fig. 146). Toruli with lower margins below lower margins of eyes (Fig. 145). Antenna with flagellum strongly clavate; clava conspicuously asymmetric (Fig. 148). Upper face and vertex with eight large setae. Head width about 2.3 × length in dorsal view and 1.1–1.2 × height in frontal view. POL 3.3–3.5 × OOL. Eye height 1.4–1.5 × length, 2.3–2.4 × malar space and 1.1–1.2 × scape length. Head width subequal to length of pedicel plus flagellum. Fu1 length 1.0–1.3 × width; fu7 width 1.70–1.85 × length; clava length 1.8–2.0× width.
MESOSOMA. Pronotal collar narrower than mesoscutum, with six large setae (Fig. 150). Mesonotum moderately setose (Fig. 150). Mesoscutum and axillae with fine punctulate reticulation (Fig. 150). Scutellar disc with similar sculpture as mesoscutum and longitudinally striate-reticulate on frenal area (Figs 150–151). Mesepisternum densely reticulate (Fig. 149). Mesepimeron mainly smooth, except for shallow striation on upper part dorsally; mesepimeral sulcus conspicuous (Fig. 149). Propodeum mainly smooth, with intricate pattern of carinae, interspaces smooth to slightly wrinkled (Fig.151). Brachypterous (Fig. 153), submacropterous or macropterous (Fig. 144). Macropterous and submacropterous forms with fore wing uniformly and densely setose except for small, elongate bare region (Fig. 152). Brachypterous form with fore and hind wings reduced and represented by stumps; fore wing with rounded or truncate apex well surpassing posterior margin of propodeum; setation similar to that of macropterous form; fore wing with complete submarginal vein, reduced marginal vein and very short postmarginal and stigmal veins (Fig. 154). Mesosoma length about 1.3 × width and 1.1–1.2× height. Pronotal collar 0.4–0.6 × as long as mesoscutum and about 0.8× as wide as mesoscutum. Mesoscutum width 2.9–3.1 × length. Scutellum about as long as broad. Propodeum length 0.6–0.7 × scutellum length. Fore wing length of macropterous form 2.2–2.3 × width; MV 4–5 × SV and 2.0–2.6 × PV. Fore wing length of brachypterous form 2.6–3.0 × width.
METASOMA. Petiole barely visible, transverse, smooth except for a few superficial longitudinal striae (Fig. 151). Gaster ovate, length 1.6–1.8 × width (Fig. 144); gt1 longest, length 1.4–1.5 × width, with hind margin produced; gt2–6 short; syntergum acutely pointed. Ovipositor sheaths slightly to distinctly protruding beyond apex of gaster. Cercal setae surpassing apex of gaster.
Male (habitus: Fig. 155)
Differs from female mainly as follows. Body length: 1.0– 2.3 mm. Flagellum uniformly brown to dark brown (Fig. 156). Mesoscutum, scutellum and axillae dark brown; mesopleuron more extensively brown
(Fig. 155). Fu1 length 2.0–2.7 × width; combined length of pedicel plus flagellum 2.7–3.0× head width. Gaster (when not inflated) much shorter than mesosoma, with only gt1 visible.
Distribution
India, Japan, Russia, Taiwan.
Remarks
See Tselikh & Mitroiu (2014) for general comments regarding the identity of the brachypterous and submacropterous specimens collected in East Asia and identified as N. ramakrishnai. Based on their original description, and taking into consideration the high intraspecific variability encountered in other species of the genus, N. ramakrishnai seems very similar to N. calicutensis and N. minuta (the latter two not treated here).
