Tetraponera penzigi

One of four ant species (also Crematogaster mimosae, Crematogaster sjostedti, Crematogaster nigriceps) that live on Acacia drepanolobium. This small arboreal ant assemblage, nesting in this dominant Africa savanna tree, have been the subject of intensive research by a large group of ecologists studying species interactions and species co-existence.

Identification
A member of the Tetraponera allaborans species-group.

Distribution based on Regional Taxon Lists
Afrotropical Region: Botswana, Ethiopia, Kenya, Uganda, United Republic of Tanzania.
