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); scutellum shiny, with sparse large punctures (Fig. 3c); 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).
Redescription. Male. BL= 9–12 mm, body blackish-brown. Head. HL: HW=0.49, head broader than long (Fig. 3a); GW: EW=0.87, eye obviously broader than gena; interocellar distance nearly twice as long as ocellocular distance (Fig. 3a); mandible blackish-brown, with one tooth on upper margin medially; frons with smooth frontal line medially (Fig. 3a); vertex with rounded posterior margin (Fig. 3b, 3d); 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); 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); ocelli normal, not enlarged; vertex behind lateral ocellus with shiny line. Mesosoma. Mesoscutum dull, densely and deeply punctuate (Fig. 3d); scutellum shiny, broader than long, with sparse large punctures (Fig. 3c); metapostnotum with broad longitudinal wrinkles; inclined part of metapostnotum widely triangular and dull (Fig. 3c); 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); tegula normal, not enlarged (Fig. 3d); legs reddish-brown; hind femur strongly developed, swollen (Fig. 3e); hind tibia with weakly C-shaped projection apically (Fig. 3e). 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); upper marginal of gonostylus rounded, upper penis valve extended, as showing in Fig. 4a (in ventral view) and Fig. 4b (in lateral view). S5 rounded apically, with two hair brushes medially (Fig. 4a); S6 deeply thickened apically (Fig. 4b); S7 as showing in Fig. 4e; S 8 as showing in Fig. 4f. Pubescence. Clypeus, supraclypeal area and frons with fine dense yellowish hairs (Fig. 5a); mesoscutum, scutellum and metanotum with sparse short hairs (Fig. 3 c–d); upper lateral surface of propodeum with sparse long yellowish hairs (Fig. 3c); legs with sparse hairs (Fig. 3b, 3d, 3f); metasomal terga with sparse yellowish hairs (Fig. 3c, 3d, 3f).
