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).
