Major: yellowish brown; occiput and space between eye and antennal fossa on each side rugoreticulate; most of rest of dorsal surface of head carinulate; antennal scape relatively long, its tip touching the sides of the head just posterior to the midpoint between the eye and level of the occipital lobe; mesonotal convexity well defined both anteriorly and posteriorly; humerus, in dorsal-oblique view low and smoothly rounded; propodeal spine moderately long and thin; postpetiole from above narrow and oval; almost all of body except gaster foveolate.

Minor: posterior half of venter of head in profile weakly concave; humerus in dorsal-oblique view subangulate; propodeal spine vertical to propodeal basal face; occiput slightly narrowed, its margin weakly concave, and nuchal collar absent. Almost all of head and mesosoma foveolate and opaque.
