Diagnosis. Male of this species can be distinguished from other species of subgenus Gnathonomia by the following: hind femur strongly developed, swollen; hind tibia with a weakly C-shaped projection apically ( Fig. 3e View FIGURE 3 ); scutellum shiny, with sparse large punctures ( Fig. 3c View FIGURE 3 ); apical margin of T1–5 with yellowish bands, and band on T1 narrower than that on T2–5 (band on T1 absent sometimes) ( Fig. 3f View FIGURE 3 ).

Redescription. Male. BL= 9–12 mm, body blackish-brown. Head. HL: HW=0.49, head broader than long ( Fig. 3a View FIGURE 3 ); GW: EW=0.87, eye obviously broader than gena; interocellar distance nearly twice as long as ocellocular distance ( Fig. 3a View FIGURE 3 ); mandible blackish-brown, with one tooth on upper margin medially; frons with smooth frontal line medially ( Fig. 3a View FIGURE 3 ); vertex with rounded posterior margin ( Fig. 3b, 3d View FIGURE 3 ); antenna reaching apical margin of tegula; scape nearly equal F1–3 together in length; F1 slightly enlarged, nearly as long as broad, nearly 0.5 times as long as F2 ( Fig. 3a View FIGURE 3 ); F2–10 nearly equal in length, almost twice as long as broad; F11 rounded apically, nearly 2.2–2.3 times as long as broad ( Fig. 3d View FIGURE 3 ); ocelli normal, not enlarged; vertex behind lateral ocellus with shiny line. Mesosoma. Mesoscutum dull, densely and deeply punctuate ( Fig. 3d View FIGURE 3 ); scutellum shiny, broader than long, with sparse large punctures ( Fig. 3c View FIGURE 3 ); metapostnotum with broad longitudinal wrinkles; inclined part of metapostnotum widely triangular and dull ( Fig. 3c View FIGURE 3 ); fore wing with three submarginal cells, 1 st submarginal cell almost equal to 3 rd submarginal cell in length, about twice as long as 2 nd submarginal cell ( Fig. 3d View FIGURE 3 ); tegula normal, not enlarged ( Fig. 3d View FIGURE 3 ); legs reddish-brown; hind femur strongly developed, swollen ( Fig. 3e View FIGURE 3 ); hind tibia with weakly C-shaped projection apically ( Fig. 3e View FIGURE 3 ). Metasoma. Metasomal terga dull, with dense shallow minute punctures; apical margin of T1–5 with yellowish bands; band on T1 narrower than that on T2–5, sometimes disappeared ( Fig. 3f View FIGURE 3 ); upper marginal of gonostylus rounded, upper penis valve extended, as showing in Fig. 4a View FIGURE 4 (in ventral view) and Fig. 4b View FIGURE 4 (in lateral view). S5 rounded apically, with two hair brushes medially ( Fig. 4a View FIGURE 4 ); S6 deeply thickened apically ( Fig. 4b View FIGURE 4 ); S7 as showing in Fig. 4e; S View FIGURE 4 8 View FIGURE 8 as showing in Fig. 4f View FIGURE 4 . Pubescence. Clypeus, supraclypeal area and frons with fine dense yellowish hairs ( Fig. 5a View FIGURE 5 ); mesoscutum, scutellum and metanotum with sparse short hairs ( Fig. 3 View FIGURE 3 c–d); upper lateral surface of propodeum with sparse long yellowish hairs ( Fig. 3c View FIGURE 3 ); legs with sparse hairs ( Fig. 3b, 3d, 3f View FIGURE 3 ); metasomal terga with sparse yellowish hairs ( Fig. 3c, 3d, 3f View FIGURE 3 ).
