Aphaenogaster is a genus of myrmicine ants. About 200 species have been described, including 18 fossil species. [1] They occur worldwide except in South America south of Colombia, sub-Saharan Africa, and Antarctica. [2]
They are often confused with Pheidole or Pheidologeton . These two have major and minor workers, while Aphaenogaster has only a single worker caste. Pheidole has three-segmented clubs on its antennae, while Aphaenogaster has four segments and a larger body size. Pheidologeton has 11-segmented antennae, while the antennae in Aphaenogaster are 12-segmented. [3]
In Australia, they often build dense, conspicuous nests. [4] Nest entrances are generally funnel-shaped with diameters up to 4 cm, which resulted in the common name funnel ants. These nests can be a serious problem for golfers or on pastures and unsealed airstrips, because the fragile surface easily collapses under pressure. [3] Where it occurs, Aphaenogaster bioturbation is an important soil and landscape process. [4]
Aphaenogaster ants probably get most of their food from tended aphids on the roots of plants, which explains that they are rarely seen on the surface. The funnel-shaped openings could play a role in trapping arthropods, which are also eaten. [3]
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development.
Messor is a myrmicine genus of ants with more than 100 species, all of which are harvester ants; the generic name comes from the Roman god of crops and harvest, Messor. The subterranean colonies tend to be found in open fields and near roadsides, openings are directly to the surface.
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.
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. 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.
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.
Anochetus is a genus of small, carnivorous ants found in the tropics and subtropics throughout the world.
Hypoponera is a genus of ants in the subfamily Ponerinae. The genus has a worldwide distribution and is found in all continents except Antarctica.
Dolichoderus is a genus of ants found worldwide.
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.
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 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 species. However, they are notable for the vast difference in size between queens and workers.
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.
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.
