Antenna with a distinct constriction between C1 and C2. Face below level of toruli with strong reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with genal carina. Vertex with weak reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; with a carina between posterior ocelli in posterior part.

Mesoscutum with sidelobes with strong reticulation, meshes isodiametric, midlobe with papillate sculpture and uniformly setose, without median groove. Mesoscutellum with papillate sculpture, partly rugose, uniformly setose except a narrow median bare stripe; submedian grooves absent. Dorsellum concave with weak sculpture, with median carina. Propodeum with a strong median carina; with strong reticulation and strong irregular carinae medially; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with six setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.

Petiole transverse. Gaster elongate; medio-basal Gt1 with a transverse carina dorsally and with short longitudinal carinae pointing backwards from carina; tergites with strong reticulation.
