T. camerunensis nests in or under rotten wood on the forest floor. It forages in the leaf litter layer and also ascends low vegetation where it has been collected by sweeping.
Identification
Bolton (2007) - A member of the Technomyrmex camerunensis group. Originally described as a variety of Technomyrmex andrei, camerunensis is easily distinguished by its decidedly different arrangement of setae. The species closest related to camerunensis appears to be Technomyrmex schoedli. They share very similar arrangements of setae, but the latter is a much more elongated species with more anteriorly located eyes, and is lighter in colour.

Description
Worker
Bolton (2007) - TL 3.0 - 4.2, HL 0.78 - 0.94, HW 0.65 - 0.83, SL 0.90 - 1.08, PW 0.44 - 0.60, WL 1.14 - 1.44 (15 measured). Indices: CI 83 - 92, SI 125 - 148, OI 26 - 28, EPI 80 - 95, DTI 154 - 182.
Frontal carina with 2 3 setae: in profile the posteriormost close to the level of the posterior margin of the eye. A single pair of setae present on the dorsum behind this, usually just behind the level of the posterior margin of the eye; this pair the longest on the dorsum and usually longer than the maximum diameter of the eye. With head in full-face view the eyes located relatively posteriorly (EPI 80 or more) and their outer margins fail to break the outline of the Sides. Anterior clypeal margin with a median excavation that is variable in depth and extent. Dorsum of mesosoma without setae but lateral margin of propodeal declivity with 1, or more rarely 2, projecting setae, located close to the level of the spiracle. Gastral tergites 1 - 4 each with long, stiff setae present, the longest of them longer than the maximum diameter of the eye. Head, mesosoma, petiole and gaster more or less uniformly dark brown to black. All coxae, femora and tibiae the same colour as the mesosoma or very nearly so; tarsi usually lighter but sometimes only slightly so.
