Cerapachys augustae, copyright Alex Wild.

Belongs within: Formicidae.

Cerapachys is a genus of ants that are specialist predators of the brood of other ants (Heterick 2009). The molecular phylogenetic analysis presented by Brady et al. (2006) suggests this genus may be paraphyletic to Sphinctomyrmex, previously distinguished by from Cerapachys by the present of constrictions between the gastral segments giving the gaster an uneven outline (Heterick 2009).

Characters (from Heterick 2009): Abdominal segments III–VII with divisions smoothly joined, so abdominal outline is even; abdominal segments V–VII with spiracles visible; dorsum of pygidium flattened, margins of flattened area armed with a series of denticles or short spines.
