Type location Cameroun (Mayr, 1895: 129, worker) collected by H. Brauns; worker only described .

Mayr's (1895) description is at . Bolton's modern description (1980) is at .

WORKER - TL 2.7-3.1 mm; mandibles smooth and shining with small pits. Head with sharply defined, spaced-out rugulae without ground sculpture between them. Thorax generally shiny although dorsum with sparse fine longitudinal rugulae. Dorsal surfaces of petiole and postpetiole also smooth and unsculptured. Colour uniform blackish-brown to black, appendages lighter (Bolton, 1980: 338, not illustrated).

Bernard (1952) described it (as camerounense) as purely western, from Congo to Ghana. From Guinea he listed findings of variety "waelbroecki" (at Mt. Nimba - 2 workers from B1.28, Ravin I of Mount Tô) but those now are synonymized with Tetramorium lucayanum. Another worker, from the same location but Station B2 41, with a yellowish, smooth petiole, which he described as a new variety without any further details, is unresolved (not lucayanum which has a petiole with rugulose sculpture).

Bolton (1980) listed findings in Ghana at CRIG (himself) and Mampong (D. Leston). Two specimens were found at Atewa Forest Reserve, from primary forest leaf litter by Belshaw & Bolton (1994b).
