Diagnosis (female). Antenna with distinct constriction between C1 and C2 (Fig. 751), flagellum slender; genal carina present; mesoscutellum (Fig. 290) with weak reticulation on median part, lateral parts with strong reticulation, meshes elongate, with a weak but complete median groove, submedian grooves distinct, straight and parallel; dorsellum with median carina; propodeum (Fig. 290) with strong reticulation, callus with four setae; coxae dark brown (Fig. 291); petiole very short, just a narrow band; gaster (Fig. 290) 2.4× as long as wide, medio-basal Gt 1 with a sharp transverse edge dorsally, tergites with strong reticulation. Small species (1.8mm), head and mesosoma black (Figs 290, 291).
