Identification
Bolton (2007) - A member of the T. pallipes complex in the Technomyrmex albipes group. A small-eyed, uniformly darkly coloured arboreal species that superficially resembles the much commoner Technomyrmex albipes but is strikingly more densely setose on the head.

Description
Worker
TL 2.1, HL 0.54, HW 0.51, SL 0.52, PW 0.32, WL 0.68. Indices: CI 94, SI 102, OI 23, EPI 70, DTI 137.
Frontal carina with 3 setae: in e the posteriormost of these at the level of the anterior margin of the eye. Dorsum of head behind this with 3 pairs of short setae and the posterior margin with a transverse row of 6 - 8 setae across its width. All dorsal setae on the head are shorter than the maximum diameter of the eye. With head in full-face view the anterior clypeal margin with a small shallow median impression; sides of head shallowly convex and the posterior margin with a slight median Impression. Eyes small, located in front of midlength and their outer margins just fail to touch the outline of the sides of the head in full-face view. With mesosoma in profile the mesonotal outline evenly shallowly convex. Number of setal pairs on dorsal mesosoma: pronotum 4; mesonotum 3; propodeal dorsum 0; lateral margin of propodeal declivity 2; all setae shorter than maximum diameter of eye. Propodeum in profile with the dorsum flat, meeting the declivity in an angle. Straight-line length of propodeal dorsum in profile is much less than depth of declivity to the spiracle. Gastral tergites 1 - 4 each with numerous setae, distributed everywhere on the sclerites; maximum length of setae on first gastral tergite less than the maximum diameter of the eye. Head/ mesosoma, petiole and gaster black. Middle and hind coxae, femora and tibiae blackish brown to black; basitarsi infuscated, slightly lighter than tibiae but not distinctly much paler.
