Diagnosis (female). Antennal clava with a weak constriction between C1 and C2 (Fig. 821); genal carina present; mesoscutellum (Fig. 470) elongate, 1.2× as long as wide, with weak reticulation on median part and with a complete median groove, lateral parts with strong reticulation, meshes elongate, submedian grooves distinct, ±straight and diverging slightly towards posterior part; propodeum (Fig. 470) with strong reticulation and some strong irregular carinae medially, callus with four setae; petiole very short, just a narrow band; gaster (Fig. 470) 2.5× as long as wide, medio-basal Gt 1 with short longitudinal carinae, tergites with strong reticulation.
