Diagnosis.
Body medium-sized. Median segments of antenna square or slightly longer than wide (Figs 1, 3), apical antennal segment rather acute, with short spine; in lateral view scapus nearly truncate and dorsally longer than ventrally (Figs 2 k, 4 i); eye glabrous, not or weakly emarginated (Figs 2 g, 4 g); face punctate, and often with a more or less distinct triangular median area (Figs 2 g, 4 g); clypeus with distinct dorsal carina (Figs 2 g, 4 g); malar suture relatively long and distinct (Figs 2 i, 4 i); labio-maxillary complex normal, not elongate (Figs 2 i, 4 i); frons distinctly concave behind antennal sockets, with deep median groove, smooth (Figs 2 h, 4 h); mesosoma largely smooth and shiny (Figs 2 c, 4 c); notauli smooth and moderately depressed (Figs 2 d, 4 d); mesoscutum smooth and evenly setose; scutellar sulcus comparatively wide, with developed crenulae (Figs 2 d, 4 d); metanotum with or without mid-longitudinal carina; propodeum with two sub-medial carinae and nearly reaching to its anterior margin, and with distinctly lamelliform carinae sub-laterally (Figs 2 d, 4 j); angle between veins 1 - SR and C + SC + R of fore wing about 50 °; fore wing vein SR 1 not reaching the tip (Figs 2 a, 4 a); fore wing veins 1 - SR + M and 1 - M not or rarely weakly curved subbasally (Figs 2 a, 4 a); fore wing vein cu-a interstitial; fore wing vein CU 1 b medium-sized, slender and reclivous (Figs 2 a, 4 a); vein 3 - CU 1 of fore wing slender; fore wing vein r oblique and shorter than width of pterostigma; second submarginal cell of fore wing long and narrow, nearly subparallel-sided or slightly narrowing distally (Figs 2 a, 4 a); hind wing vein SC + R 1 distinctly longer than vein 1 r-m (Figs 2 b, 4 b); hind wing with only 1 hamulus on vein R 1, membrane largely glabrous near vein cu-a (Figs 2 b, 4 b); claws medium-sized, ventral lobe obtuse (Figs 2 f, 4 f); metasomal tergites largely sculptured; median area of first metasomal tergite strongly convex, with well-developed dorsal and dorso-lateral carinae and a medio-longitudinal carina, often connected with several transverse carinae laterally (Figs 2 j, 4 k); second metasomal tergite with small smooth medio-basal area, and connected to median carina posteriorly, median carina extends up to posterior margin of tergite and lateral grooves developed (Figs 2 e, 4 e); second metasomal suture deep and crenulate (Figs 2 e, 4 e); third and fourth metasomal tergites with antero-lateral grooves, and latero-posterior corner protruding, more or less smooth (Figs 1, 3); third to fifth metasomal tergites with rather weak transverse posterior grooves (Figs 2 e, 4 e); hypopygium medium-sized and slightly apically acute, not emarginate medio-apically; ovipositor normal, subapically upper valve with nodus, and its lower valve with teeth ventrally (Figs 2 l, 4 l).
