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.
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.
Cardiocondyla is an Old World genus of ants in the subfamily Myrmicinae.
Harpagoxenus is a genus of ants in the subfamily Myrmicinae. Found in the Palaearctic and Nearctic ecozones of the world, Harpagoxenus was first established as Tomognathus by Mayr (1861) to house the species Myrmica sublaevis. However, the name had already been used (homonym) for a genus of fish, and was replaced with its current name by Forel (1893).
Strumigenys is a genus of ants in the subfamily Myrmicinae.
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.
Ponera is a genus of ponerine ants. The name is the Latinized form of the Ancient Greek ponira.
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.
Myrmecina is a genus of ants in the subfamily Myrmicinae. It contains 53 species distributed in North America, Europe, northern Africa, India, Korea, Japan and Australia.
Cryptopone is a genus of ants in the subfamily Ponerinae. The genus has a worldwide distribution, with most species occurring in Asia. Workers range from very small to medium in size (1.7–6.1 mm), with the queens being slightly larger.
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.
Discothyrea is a genus of small ants in the subfamily Proceratiinae. The genus is distributed in the tropics and subtropics throughout the world, where they usually nest in rotten wood, in the leaf litter, or under stones. Little is known about their biology, but ants in this genus are thought to be specialist predators of arthropod eggs and have been observed storing eggs in their nests.
Lasiomyrma is a South-East Asian genus of ants in the subfamily Myrmicinae. The genus is mainly known from tropical rainforests in Sundaland.
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.
Recurvidris is a genus of ants in the subfamily Myrmicinae. The genus is distributed in the Indomalayan realm, where the ants are found on the forest floor.
Pristomyrmex is a genus of ants in the subfamily Myrmicinae.
Metapone is an Old World genus of ants in the subfamily Myrmicinae. The genus is found in the Indo-Australian, Oriental and Malagasy regions. Most species are known only from a few specimens.
