Clypeal process semi-elliptical, apex rounded; dorsally with a low carina, distinctly visible only when viewed directly down towards mandibles, or with a sharp carina; in profile evenly curved from base to apex, apical angle slightly acute. Mandible narrow, slightly broadened at base and apex, ventral margin weakly concave; not twisted, at most weakly convex outwardly, outwardly coriaceous, somewhat dull; in ventral view evenly, moderately curved. Apex of mandible vertical, with teeth distinctly stronger ventrally. Malar space very small. Dorsal setae of head about as long as flagellar width or scarcely longer. Frons moderately punctate, about 2–3 pit widths apart. Vertex and gena setae similar to and only slightly longer than setae of frons. Frons microsculpture finely microreticulate to coriaceous, surface weakly matte. Vertex in dorsal view more or less straight, corners strongly rounded off; occipital margin not carinate but forming a pronounced ridge. Lateral ocelli nearly touching vertex crest. Ocellar triangle anterior angle strongly obtuse. Head rounded shortly posterior to eyes. Eye setae short, only about as long as 1–2 ommatidia. Dorsum of head in lateral view strongly convex, head deepest on line through eye. Venter of head posterior to mandible convex in lateral view, with relatively sparse setae. Head weakly convex ventrally, genal angle absent. Side of head posterior to eye with a line of tesselate microsculpture extending from posteroventral margin of eye to vertex crest, distinctly different from smoother sculpting dorsally and ventrally. Gena ventral to eye flat; sculpture coriaceous ventrally and posterolaterally, with broad band of tesselate-colliculate sculpture extending diagonally on each side from anterior margin of eye to posteroventral margin of head. Postgenal depression absent. Antenna extending to posterior margin of pronotum.</p><p>MESOSOMA. Anterior margin of dorsal pronotal area in lateral view evenly rounded. Pronotal setae about as long as flagellar width or scarcely longer. Propodeal disc laterally coarsely rugulose; median carina absent; transverse carina absent, brow of declivity broadly rounded; metapleural carinae complete. Profemur robust, about twice as long as wide and strongly convex dorsally, with both anterior and posterior surfaces convex, not strongly compressed, more or less straight in dorsal view.</p><p>METASOMA. Highly polished, without a trace of microsculpture. S2–5 each with a single sparse apical row of setae. Sixth sternum broadly glabrous medially, with moderately dense setae laterally.</p><p>COLOR. Body entirely dark brown to black. Antenna entirely dark brown except ventral side of basal flagellomeres yellowish. Mandible black. Coxae and femora brown, all tibiae and tarsi yellow-brown.</p><p>WINGS. Membrane tinged with yellow. Basal cells of fore wing densely and conspicuously setose.
