Mesoscutellum with very weak reticulation on median part and shiny, lateral parts with strong reticulation and eight setae, meshes elongate; submedian grooves distinct, close and parallel. Dorsellum with strong sculpture, with median carina. Propodeum with a narrow median carina that expands slightly towards posterior part; with strong reticulation; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with four setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.
