Adetomyrma is a genus of ants endemic to Madagascar. Workers of this genus are blind. The type species Adetomyrma venatrix was described in 1994, with the genus being an atypical member of its tribe, the Amblyoponini. This tribe includes the Dracula ants, members of which can feed on the hemolymph of larvae and pupae.
Pheidole is a genus of ants that belongs to the ant subfamily Myrmicinae. The genus is widespread and ecologically dominant. It probably includes more than 1000 species. The genus first evolved in the Americas, eventually spreading across the globe.
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.
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.
Barry Bolton is an English myrmecologist, an expert on the classification, systematics, and taxonomy of ants, who long worked at the Natural History Museum, London. He is known especially for monographs on African and Asian ants, and for encyclopaedic global works, including the Identification Guide to Ant Genera (1994), A New General Catalogue of Ants of the World, Synopsis and Classification of Formicidae (2003), and Bolton's Catalogue of Ants of the World: 1758-2005 (2007). Now retired, Bolton is a Fellow of the Royal Entomological Society and Myrmecologist, Biodiversity Division, Department of Entomology, Natural History Museum, London.
Cardiocondyla is an Old World genus of ants in the subfamily Myrmicinae.
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.
Crematogastrini is a tribe of myrmicine ants with 64 genera and 8 fossil genera.
Diaphoromyrma is a genus of ants in the subfamily Myrmicinae. It contains the single species Diaphoromyrma sofiae, known only from workers from the type locality in Bahia, Brazil. The genus is apparently close to Allomerus and Diplomorium in the Solenopsidini, but its tribal attribution remains uncertain.
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.
Brownimecia is an extinct genus of ants, the only genus in the tribe Brownimeciini and subfamily Brownimeciinae of the Formicidae. Fossils of the single identified species, Brownimecia clavata, are known from the Middle Cretaceous of North America. The genus is one of several ants described from Middle Cretaceous ambers of New Jersey. Brownimecia was initially placed in the subfamily Ponerinae, until it was transferred to its own subfamily in 2003; it can be distinguished from other ants due to its unusual sickle-like mandibles and other morphological features that makes this ant unique among the Formicidae. The ant is also small, measuring 3.43 millimetres (0.135 in), and a stinger is present in almost all of the specimens collected. The morphology of the mandibles suggest a high level of feeding specialization.
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.
Promyopias is an Afrotropical genus of ant in the subfamily Ponerinae containing the single species Promyopias silvestrii. The rare genus has previously been regarded as a separate genus, as a subgenus and as a provisional synonymy, but was reinstated at genus-rank in 2008.
Proiridomyrmex is an extinct genus of ants in the subfamily Dolichoderinae. The genus contains two species; Proiridomyrmex vetulus, described in 2002 where its fossils were discovered in the United States, and Proiridomyrmex rotundatus, described in 2015.
Condylodon is a genus of ant with an uncertain placement in the family Formicidae. It contains the single species Condylodon audouini, first described from a single specimen by Lund (1831) in a paper on Brazilian ants.
Pheidole bicarinata is a species of ant in the genus Pheidole. It is distributed across United States, from Nebraska, Colorado, Texas, Utah and Nevada, east to New Jersey and Florida.
