The Ants of Africa
Subfamily Formicinae

Genus Acropyga Roger (1862a: 242)


Diagnostic Features - Antennae 11-segmented. Palp formula 1,3 or 2,3. Eyes minute. Mandibles narrowly triangular, not overhung by the clypeus. Propodeum and petiole unarmed, the latter is an unarmed scale.

Roger's (1862a) genus definition is at {original description}.

Described by Bolton (1973a) as small, depigmented yellowish ants, which are hypogaeic and uncommon. Bolton (1994) had an illustration (bottom). Prins (1982: 237 ff) reviewed the situation in Southern Africa and provided much information and illustrations - see {original description}. LaPolla & Fisher (2005) recognised a third species, A. bakwele from Gabon.

Acropyga species (indet.)

Found in leaf litter (17 workers) and soil (10 workers) at four sites in Ghana (Sui River Forest Reserve, primary forest; Ofinso, cocoa; Effiduase, cocoa; Bunso, primary forest) by Belshaw & Bolton (1994a, b).

As it was unlabelled, the image right (if available) may be of this Ghanaian source but I cannot be certain.
