Major: pilosity sparse; rugoreticulum on each side of head extends between eye and antennal fossa and anteriorly almost to border of head; vertex smooth; carinulae originating on frontal lobes not quite reaching midway between level of eyes and level of occiput; pronotal dorsum in dorsal-oblique view weakly bilobous; metanotal convexity in side view symmetrical; carinulae absent from sides of propodeum; postpetiole from above symmetrical.

Minor: pilosity sparse; pronotum in dorsal-oblique view feebly bilobate; occiput in frontal view feebly convex, nearly flat, lacking nuchal collar.

Measurements (mm) Lectotype major: HW 1.30, HL 1.32, SL 0.84, EL 0.22, PW 0.66. Paralectotype minor: HW 0.68, HL 0.74, SL 0.82, EL 0.18, PW 0.44. Color Major: concolorous reddish brown. Minor: concolorous plain medium brown.
