Antenna with a constriction between C1 and C2. Face below level of toruli with weak reticulation, clypeal area smooth, frons rugose, scrobes with strong reticulation; with genal carina. Vertex with strong reticulation; with a carina between posterior ocelli in posterior part.

Mesoscutum with strong reticulation, meshes isodiametric, midlobe rugose close to notauli, without median groove, ±uniformly covered with setae but with a narrow median bare stripe. Mesoscutellum rugose with submedian grooves indicated but indistinct, ±parallel and close, ±uniformly covered with setae but with median part bare. Dorsellum with strong sculpture, with median carina. Propodeum with a strong median carina that expands only slightly in posterior part; with strong irregular carinae and strong reticulation; callus with three 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 (one seta missing in median part).

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