Sphinctomyrmex

Species of Sphinctomyrmex are specialist predators of other ants. They forage primarily below ground, only rarely on the surface. Most species lack fully winged queens and have, instead, worker-like (ergatoid) queens. Workers have a relatively heavy integument with angles and teeth for protection during raids. Nests are in soil and under stones and contain several hundred workers and up to 20 or more ergatoid queens.

Identification
Sphinctomyrmex can be separated from Cerapachys (the only other genus of the subfamily known from Australia) by the shape of the gaster. Its shape is unique to Sphinctomyrmex and should allow ready identification of members of this genus.
