Overview

Brief Summary

Acanthostichus are subterranean, predaceous ants that are infrequently collected. Numerous species are only known from a single collection and/or from a single caste (worker, queen or male).

A few species have been found in association with termites or Pogonomyrmex ant colonies. The Acanthostichus were either directly preying upon or presumably raiding these other social insects.

Diagnostic Description

MacKay 1996:

Two synapormorphies are present in the female and worker: the presence of peculiar metibial glands (Bolton 1990) and the malar grove present below the eye(Brown 1975). This groove has apparently been secondarily lost in the females of some species. Males also possess the malar groove but it can be difficult to see.
