Diagnosis
Head in dorsal view orange brown and sparsely striate (Figs 284, 291); frons and temple yellowish; frons transversely rugose (Figs 286, 293); temple smooth and shiny (Figs 285, 292); pronotum comparatively short and its lateral length 0.8–0.9 times maximum width, in dorsal view superficially sculptured and shiny (Figs 279, 280, 288, 289); propodeum shallowly and sparsely foveolate and coriaceous interspaces mostly wider than diameter of punctures (Figs 281, 290); pterostigma distinctly widened and comparatively short, 4–5 times as long as wide (Figs 278, 287); outer side of hind tibia finely carinate (Figs 294, 295).
Description
Holotype, male, length of fore wing 4.1 mm, and of incomplete body 2.8 mm (metasoma lost).
Head. Flagellum with 23 flagellomeres; coronal teeth large and distinctly carinate; frons coarsely striate (Fig. 286); vertex with several spaced striae, area near lateral ocelli rugulose (Fig. 284); temple smooth and shiny (Fig. 285), evenly convex behind eyes.
Mesosoma. Pronotum (Figs 279, 280) largely smooth and weakly sculptured; neck short and laterally with several pairs of carinae; posterior pronotum rugose, somewhat coriaceous; scutellum medially rugulose and laterally with several shallow foveolae (Fig. 281); propodeum (Fig. 281) and metapleuron coarsely shallowly foveolate.
Wings. Fore wing (Fig. 278): vein 1-M 1.5 times as long as vein 1-SR and 1.1 times vein m-cu; vein cu-a slightly antifurcal and subvertical; vein 2-SR 1.7 times as long as vein r; pterostigma distinctly widened and comparatively short, 4.5 times as long as wide; vein r ends 0.4 times length of pterostigma behind level of apex of pterostigma; vein 1-SR 1.2 times as long as parastigmal vein; basal 0.2 of vein 3-CU1 tubular, remainder largely nebulous, apically distinctly curved.
Legs. Holotype has only hind coxa left on the legs, legs described after a male from Guangxi (Longzhou). Hind coxa (Figs 282, 283, 297) largely striate, medial part of outer side compressed and more or less rugulose; hind femur (Figs 294, 295) strongly swollen, finely aciculate and with 2 large ventral teeth; hind tibia 1.2 times as long as hind femur, basal narrow part 1.7 times as long as widened part; outer side of hind tibia coriaceous and ventrally with some spaced oblique carinae; widened part of inner side distinctly depressed basally and densely setose apically; ventral length of hind basitarsus about 3.5 times as long as its apical width.
Metasoma. Metasoma of holotype lost, described after a male from Guangxi (Longzhou). First tergite coarsely transversely striate, 4.8 times as long as its width, 1.9 times as second tergite and 0.9 as rest of tergite; second tergite basally with weak rugose, rest of metasoma largely smooth, somewhat microreticulate; pygidial process distinct and tubular apically (Fig. 298).
Colour. Body varies from yellowish brown to dark brown; frons and temple yellowish (with a paler ivory streak along eye) (Figs 285, 286, 292, 293); vertex and pronotum orange brown; scutellum and propodeum dark brownish.
Distribution
