Worker
TL 1.8-1.9, HL 0.46-0.52, HW 0.35-0.39, CI 75-78, ML 0.22-0.26, MI 47-50, SL 0.27-0.32, SI 77-82, PW 0.22-0.24, AL 0.46-0.50 (10 measured).

Apicoscrobal hair present; upper scrobe margin without a similar hair at level of eye. Sculpture of side of alitrunk variable: may be entirely reticulate-punctate, or katepisternum may have a smooth patch of variable size, or katepisternum may be entirely smooth; there is sometimes also a small smooth patch on the metapleuron. Bullae of femoral glands conspicuous, those on fore and hind femora of about equal size, larger than those on middle femora. Basitarsus of hind leg with 2 very long erect fine flagellate hairs on its dorsal (outer) surface; a single similar hair on dorsal (outer) surface of hind tibia. Propodeal teeth small and slender. With petiole in profile height of anterior face of node about equal to length of dorsum of node, the two surfaces meeting through a well defined but blunt anterodorsal angle. Petiole node in dorsal view broader than long, roughly transversely rectangular. Basigastral costulae short, their length on the tergite distinctly greater than thickness of limbus but less than length of the postpetiole disc; the latter varying from feebly to quite strongly reticulate-punctate and usually also with a few weak longitudinal costulae, at least on the anterior half.
