Dorsellum with strong reticulation, with a median carina. Propodeum with a strong and wide median carina that expands posteriorly; with strong reticulation; callus with five setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with three setae on dorsal surface of submarginal vein; speculum closed; costal setal row in right wing unbroken, left wing with two setae missing in median part of setal row.

Petiole a very short transverse band. Gaster elongate; medio-basal Gt 1 with two short longitudinal carinae laterally; tergites with strong reticulation.
