Diagnosis. Vertex and eyes setose. Upper face with a transverse frontal carina (e.g. Fig. 8a), reaching from eye to eye or not close to eyes, straight or sinuate; frontovertex usually with, occasionally without, a median groove below anterior ocellus (Figs 3c, 8a). Head with a postorbital groove delimited by a postorbital carina along posterodorsal margin of eye (e.g. Fig. 2e). Occiput with transoccipital ridge (e.g. Figs 6d, 11a). Pronotum with collar more or less delimited by a carina along anterior margin, with distinct shoulders, and covered with dense setae (e.g. Fig. 2b). Shoulders of mesoscutum distinct; LLM with a round fovea behind pronotal collar (e.g. Figs 8b, 10b, 12c). Scutellum often with distinct sublateral grooves generally expressed as row of punctures (e.g. Fig. 2b). Dorsellum with lateral up-turned tooth strong and distinct, best visible in lateral view (e.g. Figs 2c, 7e). Propodeum with strong and complete plicae and with a strong and complete median carina (e.g. Fig. 2c). Callus usually with numerous setae (e.g. Fig. 2c). Female petiole transverse (e.g. Fig. 2c). Female gaster with at least tergites Gt 4 –Gt 7 piliferouspunctate (e.g. Fig. 2f); female Gt 1 with a distinct median groove in anterior inclined part, and with a rounded, eyelike patch on each side close to base (e.g. Fig. 8c).

Remarks. The diagnostic characters given above are mainly based on females, though the above generic diagnosis usually also applies to males. However, in addition to their smaller body size males often differ from conspecific females because the typically diagnostic characters are reduced and indistinct in several aspects as follows. Flagellum: funiculars usually with long setae and stalked apically (e.g. Figs 2i, 3f). Frontal carina: not as strong as in females because face usually not, or weakly, depressed below frontal carina. Dorsellum: usually less sculptured; lateral up-turned tooth reduced, indistinct. Petiole: longer. Gaster: much shorter and narrower than mesosoma; gastral tergites never piliferous-punctate; Gt 1 without inclined part and median groove anteriorly, without eye-like patches at base. In addition, males can also differ from conspecific females in the following characters. Vertex and eyes: vertex much more transverse and hence ocelli usually in an obtuse-angled triangle; vertex and eyes less setose. Fore wing: usually hyaline, not infuscate.
