Worker
Collingwood and Agosti (1996) - HL 3.0; HW 2.3; SL 2.4; EL 0.32. The clypeus projects slightly in front of the head side margins and has the front border with a broken, bluntly serrated edge. It has a distinct keel which continues posteriorly as an indented line between the frontal ridges. The head is densely sculptured, microreticulate and dull with scattered large punctures towards the genae and across the clypeus and lower frons, also the proximal third of the scape which widens from its narrow base to about 1.5 times its width near the apex. The alitrunk dorsum forms a simple arch in side view but with distinct promesonotal and mesopropodeal sutures. The petiole is a simple scale nearly as high as the propodeum. The dense sculpture of the head continues over the alitrunk; the gaster is more finely reticulostriate and the general appearance is dull without shine. In dorsal view short hairs project round the head from the occiput to the anterior genal margins. There are numerous longer hairs on the pronotum, on the posterior border of the propodeum and on the gastral dorsum.
