Major: a spike emerges from the middle carina of the clypeus; the clypeus divides into two layers, each of which projects a pair of angulate processes down and forward; carinulae originating on the frontal carinae turn outward and travel toward the sides of the head; rugoreticulum present mesad to eye; most of posterior third of dorsal head surface smooth; propodeal spines vertical to propodeal basal face.

Minor: dorsal mesosomal surface mostly covered by widely spaced transverse carinulae; propodeal spines vertical to propodeal basal face; postpetiolar node low in side view.

Measurements (mm) Holotype major: HW 1.24, HL 1.64, SL 0.64, EL 0.14, PW 0.70. Paratype minor: HW 0.64, HL 0.74, SL 0.62, EL 0.10, PW 0.42. color Major: body medium reddish brown, legs yellowish brown.
