Ant genera

Cryptopone is a genus of ponerine ants containing 23 valid species, all of which are extant. 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. Wadeura was previously synonymized under this genus, however, its two species (now four) were separated out again by Branstetter & Longino, 2022.

Wasmannia is a genus of ants. One species, Wasmannia auropunctata, is known as the electric ant or little fire ant and are considered by many countries to be a destructive, highly invasive species.

Axinidris is a genus of arboreal ants in the subfamily Dolichoderinae. The genus is known from forested areas the Afrotropics, where they nest in hollow stems or rotten wood. They forage mainly in trees, but occasionally on the ground.

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.

Adelomyrmex is a genus of ants in the subfamily Myrmicinae. Species of Adelomyrmex are small, litter-inhabiting ants most often collected in Berlese and Winkler samples. Although the genus and its relatives have a pantropical distribution, Central American cloud forests are the only places where they are abundant and diverse. Including undescribed species, Adelomyrmex has 66 species as of 2023.

Adetomyrma is a genus of ants endemic to Madagascar. Workers of this genus are blind. The type species Adetomyrma venatrix was described in 1994, with the genus being an atypical member of its tribe, the Amblyoponini. This tribe includes the Dracula ants, members of which can feed on the hemolymph of larvae and pupae.

Thaumatomyrmex is a Neotropical genus of ants in the subfamily Ponerinae, found from Mexico to Brazil. They are notable for their pitchfork-shaped mandibles, which they use to capture millipedes of the order Polyxenida. The genus is a specialist predator of polyxenids, and one of only two ant genera known to prey upon polyxenids.

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.

Acanthostichus is a predatory and predominantly subterranean genus of ant in the subfamily Dorylinae. They are found in the New World, from the southern United States to Uruguay, Paraguay and northern Argentina. They are probably common, but due to their subterranean nature, they are seldom collected or seen.

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.

Myrmoteras is a genus of ants in the subfamily Formicinae and the sole member of the tribe Myrmoteratini. They have enormous eyes, a character found in other ancient genera, and extremely elongated mandibles with eight to 16 teeth. These work as trap-jaws and can open up to 270°.

Cerapachys (common names include "raider ant" and "ant-raiding ant") is a genus of ants in the subfamily Dorylinae. Species are mainly myrmecophagous ants which raid the nests of other ants for prey. The genus is distributed widely throughout the Indomalayan region. The genus was revised by BoroWiec (2016) who split a number of previously synonymized genera out of Cerapachys, leaving only 5 species in the genus.

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 (now Harpagoxenus sublaevis). However, the name had already been used (homonym) for a genus of fish, and was replaced with its current name by Forel (1893).

Ectatomma is a Neotropical genus of ants in the subfamily Ectatomminae. The genus contains 17 described extant species and one extinct species.

This ponerine ant was recorded for the first time in French Guiana and the most northerly point of recording was in Costa Rica. The specimens reported here were collected in a region of Amazon Forest with flight interception traps.

Melissotarsus is a rare African genus of ants in the subfamily Myrmicinae. They are known from the Afrotropics and Malagasy regions, where their nests are located in living wood, built by tunneling through the wood under the bark. They are rarely seen outside of their nests, which may contribute to their perceived rarity. However, they are considered pest insects because of damage they can cause to trees, including economically important ones such as mangos and trees in the family Burseraceae, including Aucoumea klaineana, Dacryodes buettneri, and Dacryodes edulis.

Cheliomyrmex is a New World genus of army ants in the subfamily Dorylinae. In Central America, C. morosus is known from Mexico to Honduras, and Panama. C. andicola, C. audax, C. ursinus and C. megalonyx are known from Colombia and further into South America.

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 (probably spider eggs).

Leptanilloides is a genus of ants in the subfamily Dorylinae. Leptanilloides is an uncommonly collected genus with subterranean habits in the New World Andean and sub-Andean tropics.

Like other attines, they primarily grow fungi of the tribe Leucocoprini (family Agaricaceae). They use many different substrates for growing their fungi, from dry leaves and caterpillar dung to fruit matter. One of its species, Mycocepurus smithii, which lives in South America, reproduces by cloning – all ants in a colony are clones of the queen. M. castrator is a parasite of M. goeldii.
