Messor is a genus of myrmicine ants with more than 100 species, all of which are harvester ants; the generic name comes from the Roman god of crops and harvest, Messor. The subterranean colonies tend to be found in open fields and near roadsides, openings are directly to the surface.
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.
Odontomachus is a genus of ants commonly called trap-jaw 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 (tree-dwelling). These ants are sometimes known as acrobat ants.
Pseudomyrmex is a genus of stinging, wasp-like ants in the subfamily Pseudomyrmecinae. They are large-eyed, slender ants, found mainly in tropical and subtropical regions of the New World.
Leptanilla is a genus of ant in the subfamily Leptanillinae. Like other genera in this subfamily, the queen is fed by the hemolymph of their own larvae, which have specialized processes for this purpose.
Anochetus is a genus of small, carnivorous ants found in the tropics and subtropics throughout the world.
Dolichoderus is a genus of ants found worldwide.
Cephalotes alveolatus is an extinct species of ant in the subfamily Myrmicinae known from a single Middle Miocene fossil found in amber on Hispaniola. At the time of description C. alveolatus was one of seven fossil ant species placed in the Cephalotescoffeae clade.
Cephalotes integerrimus is an extinct species of arboreal ant of the genus Cephalotes, characterized by an odd shaped head and the ability to "parachute" by steering their fall if they drop off of the tree they're on. Giving their name also as gliding ants. Their larger and flatter legs, a trait common with other members of the genus Cephalotes, gave them their gliding abilities.
Cephalotes jansei is an extinct species of arboreal ant of the genus Cephalotes, originally erroneously called Exocryptocerus jansei by its discoverers, characterized by an odd shaped head and the ability to "parachute" by steering their fall if they drop from a tree, giving them the nickname of gliding ants. The species was probably native of Hispaniola, however, lack of more evidence makes this uncertain. Their larger and flatter legs, a trait common with other members of the genus Cephalotes, gave them their gliding abilities.
Stigmatomma is a genus of ants in the subfamily Amblyoponinae. The genus has a worldwide distribution, and like most other amblyoponines, Stigmatomma species are specialized predators. First described by Roger (1859), it was for a long time considered to be a synonym of Amblyopone until it was revived as an independent genus by Yoshimura & Fisher (2012) based on worker mandible morphology.
Proceratium is a rare genus of ants in the subfamily Proceratiinae. It is the type genus of the tribe Proceratiini, which in addition to Proceratium consists of two even rarer genera: the extant Discothyrea and the fossil genus Bradoponera.
Gnamptogenys is a genus of ants in the subfamily Ectatomminae. The genus has a wide distribution. It is known to occur in the Nearctic, Neotropic, Indomalayan and Australasian realms.
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.
Nesomyrmex is a genus of ants in the subfamily Myrmicinae. The genus is distributed in the Neotropical, Afrotropical and Malagasy regions. Most species live in arid climates, but some are known from the rainforest. They nest in soil or in trees. Little is known about their biology.
Carebara is a genus of ants in the subfamily Myrmicinae. It is one of the largest myrmicine genera with more than 200 species distributed worldwide in the tropics and the Afrotropical region. Many of them are very tiny cryptic soil and leaf-litter inhabitants. They nest in rotten wood to which the bark is still adherent in the Afrotropical region, or may be lestobiotic nesting near other ant species. Some species are known to exist parasitically within termite nests. Little is known about the biology of the genus, but they are notable for the vast difference in size between queens and workers.
