COLOUR. Head ( Figs 145–146View Figs 144–148) black. Mandibles reddish-yellow, teeth darker. Antenna ( Fig. 148View Figs 144–148) with scape and pedicel reddish-yellow, pedicel sometimes darker dorsally; flagellum brown, gradually becoming darker towards clava. Mesosoma ( Figs 149–151View Figs 149–154) 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, 154View Figs 149–154). Hind wing hyaline. Metasoma with petiole reddish-brown ( Fig. 151View Figs 149–154); gaster ( Fig. 144View Figs 144–148) dorsally dark brown to black, ventrally pale.

BODY LENGTH. 1.6–2.4 mm.
HEAD. Clypeus virtually smooth; apical margin slightly produced ( Fig. 147View Figs 144–148). Lower face coriaceous to shallowly reticulate, piliferous punctures not distinct. Upper face including vertex reticulate ( Fig. 146View Figs 144–148). Scrobes deep, reticulate; parascrobal region with elongate cells ( Fig. 145View Figs 144–148). Occiput coriaceousalutaceous; margin sharply defined ( Fig. 146View Figs 144–148). Toruli with lower margins below lower margins of eyes ( Fig. 145View Figs 144–148). Antenna with flagellum strongly clavate; clava conspicuously asymmetric ( Fig. 148View Figs 144–148). 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. 150View Figs 149–154). Mesonotum moderately setose ( Fig. 150View Figs 149–154). Mesoscutum and axillae with fine punctulate reticulation ( Fig. 150View Figs 149–154). Scutellar disc with similar sculpture as mesoscutum and longitudinally striate-reticulate on frenal area ( Figs 150–151View Figs 149–154). Mesepisternum densely reticulate ( Fig. 149View Figs 149–154). Mesepimeron mainly smooth, except for shallow striation on upper part dorsally; mesepimeral sulcus conspicuous ( Fig. 149View Figs 149–154).

METASOMA. Petiole barely visible, transverse, smooth except for a few superficial longitudinal striae ( Fig. 151View Figs 149–154). Gaster ovate, length 1.6–1.8 × width ( Fig. 144View Figs 144–148); 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. 155View Figs 155–156)
Differs from female mainly as follows. Body length: 1.0– 2.3 mm. Flagellum uniformly brown to dark brown ( Fig. 156View Figs 155–156). Mesoscutum, scutellum and axillae dark brown; mesopleuron more extensively brown
( Fig. 155View Figs 155–156). 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.

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).
