Major: yellow; humerus very prominent, in dorsal-oblique view extending from rest of promesonotal profile as a large equilateral triangle; in full-face view occiput much broader than clypeus, and occipital cleft shallow, giving entire head a wedge shape; rugoreticulum extensive from eye to antennal fossa posterior to frontal carina on each side of head; rest of dorsal surface of head carinulate, except for frontal triangle and mid-clypeus; all of mesosoma and waist foveolate; lateral corners of genae in full-face view right-angulate; postpetiole from above oval.

Minor: humeri bluntly spinose, with a long seta emerging form the apex of each; occiput narrow and with a nuchal collar; all of head, mesosoma, and waist foveolate to varying degree; pilosity sparse.
