Dicroaspis is an African genus of ants in the subfamily Myrmicinae. [2]
Known from central Africa, the genus contains two species. However, due to the little material available, they may represent variations the same species. [3] A third hitherto undescribed species is known from Kakamega Forest, Kenya. [4]
The genus was first described by Emery (1908), but was reclassified a few years later as a subgenus of Calyptomyrmex by Emery (1915). The taxon was finally raised to genus rank by Bolton (1981). Workers are about 2.5–3 mm long and have small eyes. Their antennae with 11 segments can be used to separate Dicroaspis from the related and similar genus Calyptomyrmex. [3] Little is known about their biology, but they appear to live in the leaf litter of rainforests. [4]
Anoplolepis, also known as the "pugnacious ants", is a genus of ants in the subfamily Formicinae and tribe Lasiini. The genus is mainly found in the Afrotropics, with a few native species known from the Malagasy and Oriental regions.
Plagiolepis is an ant genus of the formic acid-producing subfamily Formicinae. The genus is found in tropical and temperate regions of the Old World.
Plectroctena is an Afrotropical genus of ants, with most species occurring in the rainforest zones of West and Central Africa. Some species are cryptic or subterranean foragers, while others forage in open grassland terrain. The workers forage singly or in groups of 2 to 3. They nest in the earth at varying depths, or in collapsed logs. They prey mainly on millipedes, including their young or eggs.
Eutetramorium is a small genus of ants within the subfamily Myrmicinae. To date it contains three species found in Madagascar and Comoros.
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.
Probolomyrmex is a genus of ants in the subfamily Proceratiinae. The genus is distributed throughout the tropics and subtropics. The ants are very rare, and are rarely collected in the field, but they appear to be nesting in the leaf litter or in rotten wood. Little is known about their biology.
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.
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.
Microdaceton is an African genus of ants in the subfamily Myrmicinae. The genus consists of four species restricted to the Afrotropics. They nest in the leaf litter and seems to be fairly common. However, little is known about their biology.
Atopomyrmex is a small genus of arboreal ants in the subfamily Myrmicinae. The genus is known from the Afrotropics, where they nest in living wood and forage in the vegetation or on the ground.
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.
Terataner is an African genus of arboreal ants in the subfamily Myrmicinae.
Calyptomyrmex is a genus of ants in the subfamily Myrmicinae. The genus is distributed from Africa to India and east to New Caledonia. They are mainly found in the rainforest, where they forage alone or in small numbers.
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.
Ocymyrmex is an African genus of ants in the subfamily Myrmicinae, also commonly known as hotrod ants.
Tapinolepis is a genus of ants in the subfamily Formicinae. The genus is known from the Afrotropical and Malagasy regions. Nothing is known about their biology.
Leptogenys is a genus of ants in the subfamily Ponerinae. Leptogenys is the most diverse ponerine ant genus in the world; it is widespread throughout tropical and subtropical regions and there are over 260 extant species described. Most species have ergatoid queens, and many have falcate, bowed mandibles and are specialists on isopod prey.
Malagidris is a Malagasy genus of ants in the subfamily Myrmicinae. Described in 2014, the genus contains six species.
