Worker
Bolton (2000) - TL 3.3-3.7, HL 0.82-0.92, HW 0.58-0.66, CI 71-74, ML 0.52-0.58, MI 63-65, SL 0.58-0.64, SI 94-102, PW 0.34-0.40, AL 0.86-1.00 (7 measured).

Mandible without preapical dentition or with a tiny denticle close to the apicodorsal tooth (may be present on one mandible but not on the other). Proximally there may be a minute denticle on the inner dorsal margin; this may be absent, or present on one or both mandibles. Both pairs of standing hairs on cephalic dorsum stiff, simple to spatulate. Apicoscrobal hair and pronotal humeral hair flagellate; a flagellate pair present on mesonotum and similar hairs numerous on waist segments and first gastral tergite. With alitrunk in profile the pronotal ground-pilosity is very conspicuous, elongate spatulate, raised and strongly arched toward the dorsal midline. Pronotal dorsum longitudinally costulate-rugulose, the spaces between costulae almost smooth or with feeble superficial punctulation. If punctulate sculpture is present it is decidedly secondary to the strong costulate component. Mesopleuron and part to most of metapleuron smooth. Posterior (free) margin of propodeal lamella straight to weakly convex for most of its depth; propodeal lacuna conspicuous. Ventral surface of petiole with a curtain of spongiform tissue. Dorsum of petiole node with weak rugulose sculpture. Disc of postpetiole finely longitudinally costulate across its width, the costulae traversing most or all the length of the disc. Basigastral costulae distinctly shorter than length of postpetiole disc.
