The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development.
Myrmicinae is a subfamily of ants, with about 140 extant genera; 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.
Dorymyrmex is a genus of ants in the subfamily Dolichoderinae.
Trap-jaw ants are a genus (Odontomachus) of omnivorous ants found in the tropics and subtropics throughout the world.
Aphaenogaster is a genus of myrmicine ants. About 200 species have been described, including 18 fossil species. They occur worldwide except in South America south of Colombia, sub-Saharan Africa, and Antarctica.
Crematogaster is an ecologically diverse genus of ants found worldwide, which are characterised by a distinctive heart-shaped gaster (abdomen), which gives them one of their common names, the Saint Valentine ant. Members of this genus are also known as cocktail ants because of their habit of raising their abdomens when alarmed. Most species are arboreal. These ants are sometimes known as acrobat ants.
Tetramorium is a genus of ants in the subfamily Myrmicinae that includes more than 520 species. These ants are also known as pavement ants.
Crematogastrini is a tribe of myrmicine ants with 64 genera and 8 fossil genera.
Acropyga is a genus of small formicine ants. Some species can be indirect pests. A. acutiventris, which is found from India to Australia, tends subterranean, root-feeding mealybugs of the species Xenococcus annandalei. Living, gravid females are carried in the jaws of A. acutiventris queens during their nuptial flight, to establish the symbiotic association in founding colonies. Other Acropyga species have relationships with different species of mealybugs, and it could be a trait common to the whole genus.
Aenictus is a large army ant genus distributed in the Old World tropics and subtropics. It contains about 181 species, making it one of the larger ant genera of the world.
Procryptocerus is a Neotropical genus of gliding ants, with the ability to "parachute" by steering their fall if they drop off of the tree they're on.
Hypoponera is a genus of ants in the subfamily Ponerinae. The genus has a worldwide distribution and is found in all continents except Antarctica.
Trachymyrmex is a genus of fungus-growing ants in the subfamily Myrmicinae. The genus is mainly tropical in distribution, with most species being found in Central and South America.
Azteca is a strictly Neotropical genus of ants in the subfamily Dolichoderinae. The genus is very diverse and contains around 84 extant species and two fossil species. They are essentially arboreal and many species have mutualistic associations with particular plant species, where the genus Cecropia presents the most conspicuous association. In the Brazilian Amazonia, Azteca species are associated with species of Codonanthopsis.
Neivamyrmex is a genus of army ants in the subfamily Dorylinae.
Cataulacus is a genus of ants in the subfamily Myrmicinae. The genus is distributed in the Paleotropical regions, mainly in the Afrotropics. Most species are found in forests, but a few are known from more open and arid habitats.
Stenamma is a genus of cryptic leaf-litter ants that occurs in mesic forest habitats throughout the Holarctic region, Central America, and part of northwestern South America.
