Myrmicinae is a subfamily of ants, with about 140 extant genera;[1] their distribution is cosmopolitan.

The nests are permanent and in soil, rotting wood, under stones, or in trees.

[2] Myrmicine worker ants have a distinct postpetiole, i.e., abdominal segment III is notably smaller than segment IV and set off from it by a well-developed constriction; the pronotum is inflexibly fused to the rest of the mesosoma, such that the promesonotal suture is weakly impressed or absent, and a functional sting is usually present.

The clypeus is well-developed; as a result, the antennal sockets are well separated from the anterior margin of the head.

Most myrmicine genera possess well-developed eyes and frontal lobes that partly conceal the antennal insertions.
