Mesoscutellum with strong reticulation with elongate meshes; with a strong and complete median groove; submedian grooves distinct, slightly curved and diverging towards posterior part; with six setae scattered over lateral parts. Dorsellum with strong reticulation, without median carina. Propodeum with a strong median carina that is expanded in posterior part; with some strong irregular carinae and strong reticulation; callus with two 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.
