Brown (1978c) referred to a more brightly coloured form
from the West African forests.
From Guinea, Bernard (1952) listed one queen,
from Station B 8-10, Zouépo, forest, 1215 m.
Brown reported specimens from Gabon, and
Ivory Coast, at Lamto (J. Lévieux).
Collected in Ghana by Belshaw & Bolton
(1994b), who described it as widespread (43 workers from 9 sites, plus
2 workers in soil samples) in their leaf litter samples from the
semi-deciduous forest zone.
The specimens shown below include two queens matching
the type form colouration, as described by Forela (1913b), and workers
of the brighter variations.

Nigeria
specimens (Taylor, 1976: 13). TL 4.56 mm, HL 1.00, HW 1.00, SL 1.00 and
PW 0.59
Eyes large, length 0.25 mm. Overall colour castaneous, lighter on head,
legs pale yellow and shiny. Dorsum of head finely striate. Alitrunk
finely rugose. Apex of petiolar node transversely rectangular. In
addition to his diagnostic features, this was described by Brown
(1978c) as an extremely variable species, closely related to africanus.
Sizes ranging from HL 1.25 to 1.75 mm.
The drawn specimen, collected from a rotten log by Bolton at the Cocoa
Research Institute of Nigeria, Idi Ayunre, appears to match what Brown
(1978c) described as a "puzzling variant, very small in size...., with
relatively large eyes". He thought the anomalous worker could just be a
hybrid, or an undescribed species, but that it was most likely "just
another manifestation of the extreme variability".
