Diversity[1]
142 genera

Myrmicinae is a subfamily of ants, with about 140 extant genera;^[1] their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees.^[2]

Identification

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.^[3]

Tribes

Recently, the number of tribes was reduced from 25 to six:^[4]

Genera

In 2014, most genera were placed into different tribes or moved to other subfamilies. Below is an updated list:^[1][4]
