Diagnosis (minor worker). Enlarged hairs on pronotum present but limited to a band along the central 1/3 of its width; dorsal surface of head with scattered, widely spaced pubescence; mesonotum weakly arched and dorsum of mesosoma forming a shallow arch with the propodeum relatively high; dorsum of gaster the same colour as the mesosoma.
Description (minor worker). Posterolateral margin of head angular, the dorsal surface weakly convex, the lateral surface weakly concave, a ridge running from the eye to the posterolateral corner. Petiolar node low, block-like, its dorsal surface broadly convex. Individual erect hairs scattered on dorsum of mesosoma, petiole and gaster; enlarged yellow hairs present on central one-third of pronotum; pubescence thin and sparse across entire body. Colour black, gaster black with a small pale yellow spots on the anterolateral corners of the second tergite, legs dark red-black.
Measurements. Minor worker (n=3): CI 87-89, HL 1.89-2.07mm, HW 1.67- 1.85mm, ML 3.20-3.30mm, MTL 2.21-2.24mm, SI 131-151, SL 2.43-2.57mm.
Material Examined. Holotype worker and 2 worker paratypes from PT. Freeport Concession, Wapoga camp, 3,800ft. GoogleMaps, 3°14'S 136°57'E, Irian Jaya, Indonesia, 29 April 1998, R. R. Snelling, montane primary rainforest GoogleMaps, foragers on vegetation (holotype and 1 paratype in LACM, 1 paratype in ANIC). GoogleMaps
Comments. The single known collection of this species consisted of workers foraging on vegetation in a rainforest. It is presumably arboreal nesting.
