Ants (family Formicidae in the order Hymenoptera) are the most species-rich of all social insects, with more than 12,000 described species and many others awaiting description. Formicidae is divided into 21 subfamilies, of which 17 are extant and four subfamilies are extinct, described from fossils. In total more than 300 genera have been described. The subfamily was originally classified as Agroecomyrmecini, a Myrmicinae tribe until English myrmecologist Barry Bolton raised the tribe to subfamily status in 2003.

Aneuretinae

The subfamily Aneuretinae represents one extant genus and eight fossil genera established by Italian entomologist Carlo Emery in 1913. Only a single species of this subfamily is extant, the Sri Lankan relict ant (Aneuretus simoni), endemic to Sri Lanka.

Brownimeciinae

The subfamily Brownimeciinae contains the single genus Brownimecia which only has one species, Brownimecia clavata. It was described in 1997 after a fossilised specimen was collected from Cretaceous amber from New Jersey, and was initially placed in the subfamily Ponerinae.

Dolichoderinae

The subfamily Dolichoderinae was established by Forel in 1878, which represents 28 extant genera and 20 fossil genera. The subfamily presents a great diversity of species throughout the world, mainly in the tropics. Most species are generalised scavengers, but some are predacious.
