Lasius is a genus of formicine ants. The type species for this genus is the black garden ant, Lasius niger. Other major members, which live in drier heathland, are the cornfield ant, L. neoniger, and L. alienus. Other species include the temporary social parasites of the L. mixtus group and the hyper-social parasite Lasius fuliginosus. Lasius flavus is also a commonly seen species, building grassy hillocks in undisturbed pasture. In the Alps, these mounds - always aligned east to catch the first rays of the rising sun - have been traditionally used by goatherds as natural compasses.
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development.
Ponerinae is a subfamily of ants in the Poneromorph subfamilies group, with about 1,600 species in 47 extant genera, including Dinoponera gigantea - one of the world's largest species of ant. Mated workers have replaced the queen as the functional egg-layers in several species of ponerine ants. In such queenless species, the reproductive status of workers can only be determined through ovarian dissections.
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.
Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant, the erratic ant, the odorous house ant, and the cone ant. The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic regions, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions.
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.
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.
Aneuretinae is a subfamily of ants consisting of a single extant species, Aneuretus simoni, and 9 fossil species. Earlier, the phylogenetic position of A. simoni was thought to be intermediate between primitive and advanced subfamilies of ants, but recent studies have shown it is the nearest living relative of subfamily Dolichoderinae.

Azteca coeruleipennis is a species of ant in the genus Azteca. Described by Emery in 1893, the species is endemic to several countries in North America and Central America.
Azteca constructor is a species of ant in the genus Azteca. Described by Emery in 1896, the species is endemic to several countries in Central America and South America.
Azteca delpini is a species of ant in the genus Azteca. Described by Emery in 1893, the species is endemic to South America.
Azteca depilis is a species of ant in the genus Azteca. Described by Emery in 1893, the species is endemic to South America.
