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 realms, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions.
Dorymyrmex is a genus of ants in the subfamily Dolichoderinae.
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.
Oxyepoecus inquilinus is species of ant in the genus Oxyepoecus. It is endemic to Argentina. The species is listed together with two other Oxyepoecus species as "Vulnerable D2" by IUCN.
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.
Trachymyrmex is a genus of fungus-growing ants in the subfamily Myrmicinae. The genus is mainly tropical in distribution, with most species being found in Central and South America.
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.
Agroecomyrmecinae is a subfamily of ants containing two extant and two fossil genera. The subfamily was originally classified in 1930 by Carpenter as Agroecomyrmecini, a Myrmicinae tribe. Bolton raised the tribe to subfamily status in 2003, suggesting that Agroecomyrmecinae might be the sister taxon to Myrmicinae. It has since been discovered to be one of the earliest lineages of ants, a clade from the basal polytomy for all ants. In 2014, the subfamily was expanded to two tribes. The tribe Ankylomyrmini was moved from the subfamily Myrmicinae to Agroemyrmecinae.
Tatuidris, or armadillo ant, is a rare genus of ants consisting of a single species, Tatuidris tatusia. The ants are small in size and inhabit the leaf litter of Neotropical forests in Central and South America, from Mexico to Brazil. Workers are ferruginous-colored to dark red and present a distinctive morphology, consisting of a shield-like head with a broad vertex, ventrally-turned heavy mandibles which do not overlap at full closure, and unique among ants – an antenna socket apparatus sitting upside-down. Little is known about the biology of the ants, but they are likely nocturnal and specialist predators.
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.
Tropidomyrmex is a Neotropical genus of ants in the subfamily Myrmicinae. The genus contains the single species Tropidomyrmex elianae, known from Brazil.
Lenomyrmex is a Neotropical genus of ant in the subfamily Myrmicinae.
Rogeria is a genus of ant in the subfamily Myrmicinae. The genus is known from the Americas, Pacific, and Caribbean. Little is known about their biology.
Megalomyrmex wallacei is a Neotropical species of ants in the subfamily Myrmicinae. Megalomyrmex wallacei can be found in Brazil, Guyana, Colombia, Costa Rica. This species occurs in mature wet forest, usually low-elevation rainforest. Brandão (2003) reports the species nesting under leaves on the forest floor, in colonies of up to 300 workers.
Sphinctomyrmex marcoyi is a Neotropical species of ants in the subfamily Dorylinae. It is the only Sphinctomyrmex species recorded in the Amazon Forest. Gynes and males are unknown.
Lenomyrmex inusitatus is a Neotropical species of ant in the subfamily Myrmicinae. The worker of Lenomyrmex inusitatus is distinguished from other Lenomyrmex workers by smooth and shiny mesosoma with well-developed propodeal spines and by the foveolate-striate sculpture covering all the dorsal surface of its head. L. inusitatus has an unusual distribution since it is the single Lenomyrmex species recorded east of the Andes.
Acanthognathus stipulosus is a species of ant of the genus Acanthognathus. Described in 1969 by Brown & Kempf, the species is native to South America.
Oxyepoecus bidentatus is a Neotropical species of ant in the genus Oxyepoecus. The species is only known from workers from Paraguay.
