Worker
Holotype. TL 3.4, HL 0.89, HW 0.68, CI 76, ML 0.40, MI 45, SL 0.46, SI 68, PW 0.39, AL 0.94. Mandible without preapical dentition. In full-face view mandible broadest in about the third quarter of its length where the inner margin is shallowly convex, narrowing both in proximal half and distal quarter. Dorsolateral margin of head in full-face view with more than 5 simple hairs that freely project laterally, the anteriormost at the level of the eye, the posteriormost close to the occipital corner; the longest of these hairs is distinctly less than 0.50 X SL. Cephalic dorsum with standing hairs present at highest point of vertex and across occipital margin; may be 1-2 pairs between these. Dorsum of head finely but very densely reticulate-rugulose; small punctures occur within the reticulae and on the rugulae. Dorsal alitrunk longitudinally rugulose-sulcate; propodeal declivity entirely smooth. Side of alitrunk regularly longitudinally sulcate and transverse sulcate sculpture present on outer surface of front coxa. Pronotal humeral hair simple, long and filiform. Dorsal alitrunk, waist segments and first gastral tergite with numerous erect, apically acute, simple hairs that are straight to shallowly curved and slightly longer on the gaster than on the alitrunk. Dorsal and lateral surfaces of femora and tibiae with erect long fine hairs; ventral surface of femora with similar hairs and dorsal (outer) surfaces of middle and hind basitarsi with much longer hairs. Petiole in dorsal view longer than broad; disc of postpetiole scarcely broader than petiole node; both with punctulate sculpture and superimposed weak longitudinal rugulae or costulae. Petiole in profile subclavate, with a very short and shallowly inclined anterior face that is scarcely more than a continuation of the peduncle; dorsum long and low, shallowly convex.

Paratypes. TL 3.4-3.5, HL 0.89-0.92, HW 0.66-0.70, CI 73-78, ML 0.40-0.42, MI 43-47, SL 0.46-0.48, SI 68-71, PW 0.38-0.41, AL 0.90-0.95 (7 measured).
