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 tooth-like projection subapically and rectangular swollen projection apically ( Fig. 5f View FIGURE 5 ); scutellum shiny, with sparse large punctures ( Fig. 5d View FIGURE 5 ); apical margin of T2–5 covered by yellowish bands ( Fig. 5e View FIGURE 5 ).

HL: HW=0.78, head broader than long ( Fig. 5a View FIGURE 5 ); GW: EW=0.81, eye much broader than gena; interocellar distance equal to ocellocular distance ( Fig. 5a View FIGURE 5 ); mandible blackish-brown, with one tooth on upper margin medially ( Fig. 5a View FIGURE 5 ); frons and vertex with dense punctures; frons with smooth frontal line medially ( Fig. 5a View FIGURE 5 ); vertex with rounded posterior margin ( Fig. 5c View FIGURE 5 ); antenna reaching apical margin of tegula ( Fig. 5b View FIGURE 5 ); scape nearly equal to F1–3 together in length ( Fig. 5a View FIGURE 5 ); F1 slightly enlarged and nearly as long as broad ( Fig. 5a View FIGURE 5 ), nearly 0.5 times as long as F2 ( Fig. 5a View FIGURE 5 ); F2–10 almost equal in length, nearly twice as long as broad; F11 rounded apically, about twice as long as broad; ocelli normal, not enlarged. Mesosoma. Mesoscutum dull, minutely and deeply punctuate; scutellum shiny, broader than long, with sparse large punctures, punctures in median sparser than that on posterior margin upper lateral surface of propodeum with sparse punctures; metapostnotum with narrow longitudinal wrinkles; inclined part of metapostnotum narrowly triangular and dull ( Fig. 5c, 5d View FIGURE 5 ); 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. 5d View FIGURE 5 ); tegula normal, not enlarged ( Fig. 5c View FIGURE 5 ); legs reddish-brown ( Fig. 5b, 5f, 5e View FIGURE 5 ); hind femur strongly developed, swollen ( Fig. 5b, 5f View FIGURE 5 ); inner surface of hind tibia with tooth-like projection subapically and rectangle swollen process apically ( Fig. 5f View FIGURE 5 ). Metasoma. Metasomal terga dull, with dense minute punctures; apical margin of T1 without conspicuous white band ( Fig. 5e View FIGURE 5 ); apical margin of T2–5 with yellowish bands, punctures on T1–2 larger and denser than on T3–4 ( Fig. 3d, 3e View FIGURE 3 ); S5 rounded apically, apical margin with two hair brushes medially ( Fig. 6a View FIGURE 6 ); S6 deeply thickened apically ( Fig. 6b View FIGURE 6 ); S7 as showing in Fig. 6e; S View FIGURE 6 8 View FIGURE 8 as showing in Fig. 6f View FIGURE 6 ; upper margin of gonostylus rounded, as showing in Fig. 6a View FIGURE 6 (in ventral view) and Fig. 6b View FIGURE 6 (in lateral view).
