Mesoscutellum with weak reticulation on median part and with a very weak median groove, lateral parts with strong reticulation, meshes elongate, with eight scattered setae on lateral parts; outer margin of submedian grooves indistinct, grooves curved. Dorsellum with strong reticulation, with median carina. Propodeum with a strong and wide median carina that expands backwards from median part of carina; with strong irregular carinae and strong reticulation; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with very weak reticulation. Fore wing with 6&7 setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Petiole transverse with strong sculpture on dorsal part. Gaster elongate; medio-basal Gt1 with longitudinal carinae laterally; tergites with strong reticulation.
