Worker
Minor (n=3): CI 90–93, HL 1.73–2.06 mm, HW 1.56–1.91 mm, ML 2.87–3.00 mm, MTL 1.99–2.17 mm, SI 128–146, SL 2.27–2.45 mm. Major worker (n=2): CI 101–105, HL 2.54–3.16 mm, HW 2.56–3.31 mm, ML 3.19–4.47 mm, MTL 2.17–2.28 mm, SI 71–90, SL 2.31–2.36 mm.

Minor. Posterolateral margin of head angular, the dorsal surface weakly convex, the lateral surface weakly concave (more so in smaller workers, less so in larger workers), a ridge running from the eye to the posterolateral corner. Petiolar node tapering dorsally into a blunt angle. Individual erect hairs scattered on dorsum of mesosoma, petiole and gaster; enlarged yellow hairs present on dorsal surface of pronotum; pubescence thin and scattered across entire body. Colour black, legs red-black.
