Diagnosis (female). Antennal clava with a weak constriction between C1 and C2, scape dark brown (Fig. 1091); genal carina present; mesoscutellum ( Fig. 556 ) with weak reticulation on median part and with a weak median groove, lateral parts with strong reticulation, meshes elongate, submedian grooves distinct, diverging slightly towards posterior part; dorsellum with median carina; propodeum ( Fig. 556 ) with strong reticulation, callus with six setae; petiole transverse and smooth; gaster ( Fig. 556 ) 2.8× as long as wide, medio-basal Gt1 with longitudinal carinae laterally, Gt1 with weaker reticulation and more shiny than remaining tergites that have strong reticulation.

Mesoscutellum with weak reticulation on median part and with a weak median groove, lateral parts with strong reticulation, meshes elongate; submedian grooves distinct, diverging slightly towards posterior part; with eight setae scattered over lateral parts. Dorsellum with weak sculpture and shiny, with median carina. Propodeum with strong reticulation; callus with six setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with five setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken.

Petiole transverse and smooth. Gaster elongate; medio-basal Gt 1 with longitudinal carinae laterally, Gt 1 with weaker reticulation and more shiny than remaining tergites that have strong reticulation.
