Description
DIAGNOSIS Major: distinguished within the punctatissima group by the combination of the 3-lobed promesonotal profile in side view, with the mesonotal (rearmost) convexity flat-topped; long, robust propodeal spine; completely rugulose posterior half of the head, reaching all the way to the occiput; completely foveolate and opaque first gastral tergite; and dense pilosity.

Minor: head, mesosoma, and waist entirely foveolate and opaque; occiput narrow, with a very thin nuchal collar.

Both castes are yellow.

MEASUREMENTS (mm) Holotype major: HW 0.96, HL 0.94, SL 0.66, EL 0.16, PW 0.40. Paratype minor: HW 0.46, HL 0.54, SL 0.68, EL 0.10, PW 0.32.
