Mesoscutellum with strong reticulation on median part and with a complete median groove, lateral parts with strong reticulation and with six scattered setae, meshes elongate; submedian grooves distinct, slightly curved and diverging towards posterior part. Dorsellum with weak sculpture and shiny, with median carina. Propodeum with a wide median carina that expands strongly posteriorly; with strong irregular carinae and strong reticulation; callus with four 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 broken.
