Brown (1963: 8) after listing his synonymies, simply noted -
"This species occurs widely in Africa south of the Sahara. In addition to the types mentioned above, I have seen samples from Liberia, Cameroons and the Kalahari Desert. There is some small variation among these samples in relative head width and in strength and opacity of the sculpture, but this appears to be both size-linked(allometric) and continuous."
Brown makes no mention of the clear separation between nigeriensis with eyes of 18-20 facets and brunoi with 4 or 6 "ill-defined facets" (Arenold, 1915)

{Pachycondyla brunoi}Nigeria specimens (as Trachymesopus brunoi, Taylor, 1976: 31)-
TL 4.75 mm, HL 0.96, HW 0.93, SL 0.68, PW 0.68 . Colour black, red-brown extremities and appendages. Sculpture of fine dense puncturation, relatively dense pilosity all over. Mandibles with a basal fovea on dorsolateral surface. Clypeus carinate medially. Eyes small. Metanotal groove very weakly impressed. Dorsum of propodeum narrower than that of pronotum.

Wheeler (1922) listed nigeriensis from Ghana (Aburi, F. Silvestri).

From Guinea, Bernard (1952) recorded a single dealated queen (as Euponera (Trachymesopus) lamottei), collected from Kéoulenta savanna (27-iii-1942, Lamotte), remarking that the nearest relative he had seen was Euponera sharpi Forel, known by workers only from Singapore.

Brown (1963) reported that, in addition to the types, he had seen specimens from Cameroun, Liberia and the Kalahari Desert and that there was some small variation in relative head width and in strength and opacity of the sculpture, but that appeared to be both size-linked (allometric) and continuous.

In Nigeria collected in soil and from a dead log (B. Bolton), often found with termites (Bolton, 1973a).

Described as widespread in the Ghana semi-deciduous forest zone, from leaf litter sampling, 24 workers, and soil, 9 workers, by Belshaw & Bolton (1994b).
