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.

{Anochetus bequaerti} 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".
