Anterior margin of pronotum marginate, its central plate smooth, mesonotum irregularly longitudinally striate, dorsum of propodeum transversely rugulose. Sides of pronotum longitudinally rugulose, mesopleura and sides of propodeum longitudinally rugulose and coarsely punctuate. appearing dull. Petiole finely punctuate, postpetiole dorsum and gaster smooth and shining.
