Major: head quadrate; almost all of anterior two-thirds of dorsal surface of head (except frontal triangle, antennal fossae, and clypeus) rugoreticulate, and posterior third foveolate; anterior half of pronotal dorsum rugoreticulate; antennal scape near base slightly broader than near tip; pronotum weakly bilobous in dorsal-oblique view; metanotum convex in side view; petiole thick in side view, but the apex of its node tapering almost to a point; median strip of entire first gastral tergite shagreened and opaque.

Minor: all of head, mesosoma, and waist foveolate and opaque; anterior half of median strip shagreened.

MEASUREMENTS (mm) Holotype major: HW 1.70, HL 1.80, SL 1.02, EL 0.26, PW 0.92. Paratype minor: HW 0.66, HL 0.84, SL 1.04, EL 0.18, PW 0.54.
