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] All species of Cephalotes (within the tribe Attini) are gliding ants.

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

In 2015, the number of tribes was reduced from 25 to six. [4]

Phylogeny

The relationships between the six myrmicine tribes have been debated, and the most recent 2025 phylogeny is shown here. [5]

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