Apterostigma megacephala, a new species of attine ant, is described from Peru and Colombia. It is diagnosed by the following combination of worker characters: flattened compound eyes partially wrapped around conical tubercles, mesonotal denticles and erect rigid pilosity on the head, mesosoma and gaster. It is thought to be a basal species in relation to the rest of Apterostigma. Phylogenetic relationships among basal genera of the tribe Attini are discussed.
