The Higher Classification of the Ant Subfamily Ponerinae (Hymenoptera: Formicidae), with a Review of Ponerine Ecology and Behavior Author Schmidt, C. A. Author Shattuck, S.

Taylor (2008) informally divides the genus into three species, but we are following the traditional division of two species until a formal study of species-level taxonomy is published. See Arnold (1951) for a key to species.
