Opisthopsis is a genus of ants in the subfamily Formicinae. [2] Its 13 species are found in Australasia. [3]
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development.
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.
Tapinoma is a genus of ants that belongs to the subfamily Dolichoderinae. The genus currently comprises 74 described species distributed worldwide in tropical and temperate regions. Members of are generalized foragers, nesting in a wide variety of habitats, ranging from grasslands, open fields, woodlands, to inside buildings. The majority of species nest in the ground under objects such as stones or tree logs, other species build nests under bark of logs and stumps, in plant cavities, insect galls or refuse piles.
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.
Formicoxenus is a genus of ants in the subfamily Myrmicinae.
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.
Tetramorium is a genus of ants in the subfamily Myrmicinae that includes more than 520 species. These ants are also known as pavement ants.
Myrmecina is a genus of ants in the subfamily Myrmicinae. It contains 53 species distributed in North America, Europe, northern Africa, India east, Korea, Japan and Australia.
Hypoponera is a genus of ants in the subfamily Ponerinae. The genus has a worldwide distribution and is found in all continents except Antarctica.
Cyphomyrmex is a genus of fungus-growing ants in the subfamily Myrmicinae.
Technomyrmex is a genus of ants in the subfamily Dolichoderinae. With 98 species, it is one of the largest and most diverse ant genera in the Dolichoderinae. The genus distributed throughout the tropical and subtropical zones with most species occurring in the Oriental-Malesian and Afrotropical regions. One species, Technomyrmex albipes is a tramp ant now widespread throughout the tropics due to human activities.
Xenomyrmex is a genus of small ants in the subfamily Myrmicinae. The genus is known from Florida, the West Indies, and from Mexico to at least Panama. They nest in cavities of living or dead plants.
Vollenhovia is a genus of ants in the subfamily Myrmicinae.
Carebara is a genus of ants in the subfamily Myrmicinae. It is one of the largest myrmicine genera with more than 174 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 species. However, they are notable for the vast difference in size between queens and workers.
Lepisiota is an Old World genus of ants in the subfamily Formicinae. They nest in rotten wood, in standing trees or in the ground, generally in less forested areas.
Melophorus is a genus of ants in the subfamily Formicinae and the sole member of the tribe Melophorini. The genus is endemic to Australia, where its species are common in arid and semiarid areas.
Pseudolasius is a genus of ants in the subfamily Formicinae. The genus is known from southern Asia to northern Australia, where it appears to be restricted to tropical areas.
Chronoxenus is a genus of ants in the subfamily Dolichoderinae. The genus is known from Asia.
Lioponera is a genus of ants in the subfamily Dorylinae containing approximately 74 described species. The genus is distributed widely across the Afrotropical, Australasia, Indomalaya, Malagasy, and Palearctic bioregions. Lioponera was described by Mayr (1879) and later placed as a junior synonym of Cerapachys by Brown (1975). Lioponera was resurrected as a valid genus by Borowiec (2016) during redescription of the doryline genera.
