This species has been found in a range of forested areas, from rainforest to rubber plantations. It has most often been collected in litter samples.

Identification
Bolton (2007) - A member of the Technomyrmex bicolor group. Closely resembling Technomyrmex obscurior but with a shorter propodeum that has a weakly convex dorsum, and with middle and hind coxae that are about the same colour as the femora.

Worker
Bolton (2007) - TL 3.7 - 3.9, HL 0.79 - 0.85, HW 0.70 - 0.74, SL 0.92 -0.96, PW 0.51 - 0.53, WL 1.20 - 1.26 (7 measured). Indices: CI 85 - 89, SI 130 - 135, OI 28 - 30, EPI 69 - 82 DTI 157 - 163.

Head behind clypeus, dorsum of mesosoma, declivity of propodeum and first gastral tergite all entirely lack setae. Gastral tergites 2 - 4 with long stout setae present that are sli~htly longer than the maximum diameter of the eye: second gastral tergite with 2 – 3 pairs, third and fourth tergites each with 3 - 4 pairs. Anterior clypeal margin with an approximately semicircular median notch. The margins of the notch meet the lateral portions of the anterior margin through rounded curves, not sharp angles. Posterior margin of head evenly shallowly concave. With head in full-face view the outer margins of the eyes fail to touch the outline of the convex sides of the head. Scape index 130 or more. In dorsal view the metathoracic spiracles are separated from the metanotal groove by a distance slightly more than one spiracle diameter. Mesosoma relatively long, DTI 157 - 163. In profile the propodeal dorsum shallowly convex, its straight-line length less than the depth of the declivity to the spiracle. In profile the head, mesosoma, petiole and gaster all the same shade of brown, or very nearly so. Anterior coxa brown; middle and hind coxae dull yellow and lighter than the mesosoma. All trochanters yellow. Middle and hind femora and tibiae the same dull yellow colour as their coxae or very nearly so (femora may be slightly infuscated medially). Tarsi somewhat lighter than the femora and tibiae.
