Worker
Holotype. TL 1.7, HL 0.48, HW 0.38, CI 79, ML 0.15, MI 31, SL 0.20, SI 53, PW 0.22, AL 0.46. Characters of prosopis-complex. Dorsolateral margin of head with narrowly spoon-shaped curved hairs on upper scrobe margin to level of apex of scrobe; these hairs similar in shape and size to those on leading edge of scape. Posterior to this are shorter, narrower hairs that are more strongly appressed; there is no apicoscrobal hair. Cephalic dorsum with a single standing hair at apex of each occipital lobe, otherwise standing hairs absent. Pronotal humeral hair absent. Dorsum of promesonotum and waist segments without standing hairs. Propodeal declivity with a broad lamella whose posterior margin is confluent with the propodeal tooth to its apex. First gastral tergite with a single pair of erect stiff hairs, near the base. Cephalic dorsum finely and weakly reticulate-punctate, the entire dorsal alitrunk smooth. Dorsum of petiole node unsculptured.

Paratype. TL 1.7-1.8, HL 0.48-0.49, HW 0.38-0.39, CI 78-81, ML 0.15-0.16, MI 31-33, SL 0.20-0.22, SI 53-56, PW 0.22-0.24, AL 0.45-0.50 (3 measured).

Dimensions of non-paratypic workers. HL 0.50-0.52, HW 0.39-0.44, CI 78-84, ML 0.16-0.17, MI 31-34, SL 0.22-0.23, SI 53-56. In some but not all of these the gaster lacks the basal pair of hairs; these may have been lost by abrasion.
