Head in full face view oval, wider behind than in front, posterior margin evenly convex without distinct posterior corners; sides in front of the eyes straight. Eyes relatively large and convex. Ocelli small. Pronotal and propodeal sides immarginate. Pronotal teeth small and robust. Propodeal dorsum distinctly wider than long, arched both longitudinally and transversely. Propodeal ridges small and far apart, between them the propodeal dorsum smoothly merges into the declivity. Petiole with a mid pair of diverging and slightly backward bent spines, whose reciprocal distance is about twice the length of each spine, and a pair of much shorter lateral teeth raising near the bases of the spines.
