Worker
Bolton (2000) - TL 2.3-2.5, HL 0.59-0.65, HW 0.43-0.46, CI 69-74, ML 0.13-0.15, MI 21-25, SL 0.28-0.34, SI 67-74, PW 0.26-0.30, AL 0.58-0.66 (20 measured).

Mandibular teeth strong and conspicuous, the first tooth following the basal lamella without a diastema. Anterior clypeal margin appearing transverse but at higher magnifications seen to be very shallowly convex. Lateral margins of clypeus with narrowly spatulate projecting hairs that are J-shaped and distinctly curved posteriorly; hairs on anterior clypeal margin not curved away from midline. Dorsum of clypeus with narrowly spatulate curved hairs. Apicoscrobal hair fine, curved filiform to sub flagellate, not strongly distinguished from, nor much longer than, the other dorsolateral marginal pilosity. Leading edge of scape with hairs of the secondary row almost as long and strongly developed as those of the primary row, but more strongly curved. All hairs of the secondary row curve strongly toward the apex of the scape; most hairs of the primary row are similarly oriented but near the subbasal bend one or two of the longest hairs are shallowly curved (at least in the apical third) toward the base of the scape. Cephalic ground-pilosity extremely narrowly spatulate. Dorsal alitrunk with fine curved hairs, some longer and finer than others but lacking strikingly elongate flagellate hairs. Dorsal (outer) surface of hind basitarsus with a long flagellate hair; no such hair on the tibia.
