Cardiocondyla is an Old World genus of ants in the subfamily Myrmicinae. [2]
Approximately 70 species are currently recognized as belonging to this genus, most of which are distributed in the Old World tropics and subtropics, but a few of which occur in the temperate zone. Some species are also found widely separated in North America and the Pacific Islands, as a result of human introduction. [3]
Several species of this genus have a striking male polymorphism, with both winged and wingless forms. These males differ not only in morphology, but also in reproductive tactics. [3] Closely related genera are Leptothorax , Stereomyrmex and Romblonella . [4]
Cardiocondyla elegans worker ants transport young queen ants to alien nests to promote outbreeding. [5] This allows avoidance of inbreeding depression. The worker ants, sisters of these queens, may transport the queens several meters from their natal nest and drop them off at another, alien nest to promote outbreeding with wingless stationary males in a process somewhat analogous to third party matchmaking in humans. [5] After mating during the winter, the sexual females may depart in the spring and find their own colonies.
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.
Myrmica is a genus of ants within the subfamily Myrmicinae. It is widespread throughout the temperate regions of the Holarctic and high mountains in Southeast Asia.
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.
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.
Tetramorium is a genus of ants in the subfamily Myrmicinae that includes more than 520 species. These ants are also known as pavement ants.
Crematogastrini is a tribe of myrmicine ants with 64 genera and 8 fossil genera.
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.
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.
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.
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.
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.
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.
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.
Nylanderia is a large genus of ants in the subfamily Formicinae. The genus has a nearly cosmopolitan distribution with species inhabiting a wide array of habitats in almost all geographic regions. Nylanderia, currently containing over 110 species, is an ecologically important genus, with some species reported as being invasive. The ants are small to medium in size and range in color from pale yellow to black.
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.
Ectomomyrmex is a ponerine genus of ants found in Asia and Australia. Little is known about their biology, but they seem to be generalist predators of arthropod prey.
