Petiolar node high, sub triangular in profile view, roundly convex at tip, longer than postpetiole which rounded and lower than petiolar node, and as broad as petiolar node in dorsal view. Gaster oval, anterior border straight in dorsal view.

Smooth and shining in the entire body. Erect hairs moderately dense, mixed up with decumbent short hairs on head; antennal scapes and dorsum of hind tibia with abundant suberect hairs.
