Octostruma is a genus of ants in the subfamily Myrmicinae. [2] The genus is found in the Neotropics. [3]
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.
Cephalotes is a genus of tree-dwelling ant species from the Americas, commonly known as turtle ants. All appear to be gliding ants, with the ability to "parachute" and steer their fall so as to land back on the tree trunk rather than fall to the ground, which is often flooded.
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.
Megalomyrmex is a genus of ant in the subfamily Myrmicinae. The genus is known only from the Neotropics, where some of the species are specialized parasites or predators of Attini.
Anochetus is a genus of small, carnivorous ants found in the tropics and subtropics throughout 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.
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.
Dolichoderus is a genus of ants found worldwide.
Cyphomyrmex is a genus of fungus-growing ants found primarily in South and Central America. However, some species do come up to the southern portion of North America. They grow a variety of fungi in the tribe Leucocoprineae. Most fungal gardens are grown in small nodules, some species to cultivate entire mycelium, though. Colonies are monogynous and are relatively small with about 100 workers on average.
Hylomyrma is a genus of ants within the subfamily Myrmicinae. To date it contains 30 known species.
Rhopalothrix is a genus of ants in the subfamily Myrmicinae.
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.
Heteroponera is a genus of ants in the subfamily Heteroponerinae. The genus is known from the Neotropics and Australasia.
Eurhopalothrix is a genus of ants in the subfamily Myrmicinae.
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.
Myrmelachista is a Neotropical genus of ants in the subfamily Formicinae. The genus is found exclusively in the Neotropical realm. Little is known regarding their biology.
