Diagnosis
Antenna with 34 flagellomeres, beyond middle slightly widened; apically cylindrical. Subocular sulcus absent. Second tergite (Fig. 33) slightly shagreened, with unclear granulose sculpture, approximately 1.7× as long as apical width. Propodeal spiracle oval, 2.1× as long as wide. Metapleuron black, with large median white spot. Hind second to fourth tarsomeres white.

Female
MEASUREMENTS. Body length approximately 9.8 mm. Fore wing length approximately 7.8 mm.
HEAD. Face (Fig. 28) almost shiny, approximately 1.4× as wide as long, evenly convex, with dense fine punctures; upper margin with even median concavity. Clypeal suture vestigial. Clypeus approximately 2.4× as wide as long, with sculpture as face but punctures relatively sparser; apical margin convex, median 0.25 thick. Upper and lower margins of mandible almost parallel, basally with dense fine punctures, apically with sparse indistinct punctures; upper tooth approximately 1.5× as long as lower tooth. Subocular sulcus absent. Malar space 0.7× as long as basal width of mandible. Gena evenly longitudinally convex, shiny, with sparse, indistinct fine punctures. Vertex (Fig. 29) slightly shagreened. Interocellar area convex, postocellar line approximately 1.6× as long as ocular-ocellar line. Frons almost flat, upper portion with sculpture as vertex, lower median portion smooth, concave. Antenna with 34 flagellomeres, slightly widened beyond meddle, apically cylindrical. Ratios of lengths from first to fifth flagellomeres: 9.5:7.4:6.7:6.3:5.7. Occipital carina thin, complete, lower end reaching base of mandible.
MESOSOMA. Pronotum (Fig. 30) almost smooth, with indistinct fine punctures dorso-posteriorly. Epomia distinct. Mesoscutum convex, shagreened. Notaulus distinct, reaching to line between anterior margins of tegulae. Scutoscutellar groove smooth. Scutellum almost flat, with weak fine punctures; lateral carina approximately 0.7× length of scutellum. Postscutellum almost shiny, evenly transversely convex; anterior margin shallowly concave. Mesopleuron (Fig. 31) slightly shagreened; medially with fine transverse wrinkles; antero-dorsally, beneath subalar prominence, with fine oblique longitudinal wrinkles. Speculum with distinct fine punctures. Upper end of epicnemial carina reaching about 0.5 height of posterior margin of pronotum, distant from front margin of mesopleuron. Metapleuron shagreened, with indistinct, irregular short wrinkles; juxtacoxal carina anteriorly present; juxtacoxal area smooth, shiny. Submetapleural carina complete, strong. Wings slightly brownish, hyaline. Fore wing with vein 1cu-a opposite 1-M. Areolet pentagonal, receiving vein 2m-cu at its middle. 2-cu as long as 2cu-a. Hind wing vein 1-cu about 5.5× as long as cu-a. Ratio of length of hind tarsomeres 1:2:3:4:5 is 8.5:3.4:2.7:1.2:2.1.
Claw simple. Area superomedia, basal and apical transverse, lateral longitudinal and pleural carinae of propodeum (Fig. 32) complete. Area externa with indistinct fine punctures. Area superomedia, area dentipara with irregular wrinkles. Area posteroexterna with oblique longitudinal wrinkles. Area lateralis with oblique transverse wrinkles. Area petiolaris with dense transverse wrinkles. Propodeal spiracle elliptical, maximum diameter approximately 2.1× as long as minimum diameter, connected to pleural carina by carina.
METASOMA. First tergite approximately 3.1× as long as apical width; median dorsal, dorsolateral and ventrolateral carinae absent; petiole with dense fine punctures; postpetiole shagreened, hind margin smooth, sides convergent posteriorly. Tergites 2 to 4 almost parallel-sided. Tergites 2, 3 (Fig. 33) shagreened. Tergite 2 approximately 1.7× as long as apical width; thyridia approximately 1.8× as wide as distance between thyridia, about as wide as distance to base of second tergite; spiracle located at basal 0.45. Tergite 3 approximately 1.3× as long as maximum width. Tergite 4 with sculpture as tergite 3, posteriorly with more or less distinct fine punctures, 0.9× as long as maximum width. Tergite 5 (Fig. 34) almost shiny, slightly shagreened, with sparse, fine punctures, apical margin with small median membranous area. Tergite 6 slightly shagreened and sparsely punctate, with large apical median membranous area. Ovipositor sheath approximately as long as apical depth of metasoma, slightly widened apically. Ovipositor curved upwards, upper valve with transverse ridges; lower valves with oblique longitudinal ridges.
COLOR (Fig. 27). Black, except following: flagellomeres 8–14 dorsally, hind tarsomere 1 apically, 2–4, and tarsomere 5 basally white. Following yellowish white: face, except small median brown black spot, clypeus, except smooth brown apical margin, mandible, except apical teeth, malar area, gena, except dorso-posteriorly, lateral wide longitudinal band of frons, anterior margin and upper posterior portion of pronotum, small submedian spot of mesoscutum, subalar ridge, large irregular transverse band ventrally on mesopleuron, upper division of metapleuron, large median spot of metapleuron, scutellum, postscutellum, area posteroexterna of propodeum, fore and mid coxae and trochanters, hind coxa dorsally, basally, dorsal spot of hind first trochanter, basal median spot and apical transverse band of tergite 2. Fore and mid legs ventrally, except mentioned above, light brown, dorsally blurry dark brown. Hind trochantellus, hind femur basally and ventrally, hind tibia ventrally on basal half red brown. Hind tibia brown-black basally, dorsally. Thyridia, tergite 3 posteriorly and subsequent tergites more or less dark brown. Pterostigma brown. Veins brown-black.
Male
Body length approximately 9.0 mm. Fore wing length approximately 6.5 mm. Antenna with 30 flagellomeres. Fore wing with vein 1cu-a slightly basal to 1-M. Face entirely, mesopleuron except upper margin, mesosternum yellowish white. Propodeum almost entirely dark brown. Hind tarsus brownblack.
Remarks
This new species is similar to N. polyambonios Kusigemati, 1986 and N. albimaculatus Sheng & Sun sp. nov., but can easily be distinguished from N. polyambonios by tergite 5 (Fig. 34) slightly shagreened, with sparse, fine punctures, apical margin with very small median membranous area; tergite 5 of N. polyambonios smooth, with very large median membranous area. This new species can be distinguished from N. albimaculatus sp. nov. by the following combination of characters: tergites 2 (Fig. 33) approximately 1.7× as long as apical width; metapleuron with large median white spot; apical margin of tergite 5 with very small median membranous area; hind tarsomere 1 apically, 2–4, and tarsomere 5 basally white. N. albimaculatus sp. nov.: tergite 2 (Fig. 8) approximately 2.1× as long as maximum width; Metapleuron entirely blackish brown; hind tarsus brown.
