Hypoponera aprora

Identification
Bolton and Fisher (2011) - This species is immediately distinguished from all its Afrotropical and West Palaearctic congeners by its lack of the prora on the first gastral sternite, both laterally and anteroventrally. It belongs in the occidentalis complex of the abeillei group, notes on the species of which are given under occidentalis. See also under Hypoponera dis, which appears to be its closest relative.

Distribution
This taxon was described, and is only known, from Tanzania.
