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).
