Oxyepoecus is a Neotropical genus of ant in the subfamily Myrmicinae. The genus is a member of the tribe Solenopsidini and currently includes 20 species.
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.
Eulithomyrmex is an extinct genus of ant in the formicid subfamily Agroecomyrmecinae. The genus contains two described species, Eulithomyrmex rugosus and Eulithomyrmex striatus. Eulithomyrmex is known from a group of Late Eocene fossils which were found in North America.
Agroecomyrmex is an extinct genus of ants in the formicid subfamily Agroecomyrmecinae, for which it is the type genus. The genus contains a single described species, Agroecomyrmex duisburgi. Agroecomyrmex is known from a group of Middle Eocene fossils which were found in Europe.
Peronomyrmex is a rare genus of ants in the subfamily Myrmicinae. Its three species are known from the east coast of Australia. With only five specimens in total, collected from four localities, Peronomyrmex is one of the world's most rare ant genera.
Meranoplus parviumgulatus is a species of ant in the genus Meranoplus. It is known from New Guinea and Papua New Guinea.
Cyphoidris is a genus of ants in the subfamily Myrmicinae. The genus is known from Africa.
Indomyrma is an Asian genus of ants in the subfamily Myrmicinae. The genus contains two species: the type species Indomyrma dasypyx known from India and Indomyrma bellae known from Vietnam.
Lasiomyrma is a South-East Asian genus of ants in the subfamily Myrmicinae. The genus is mainly known from tropical rainforests in Sundaland.
Proatta is a Southeast Asian genus of ants in the subfamily Myrmicinae. It contains the single species Proatta butteli, known from the Malay Peninsula, Borneo and Sumatra.
Bondroitia is a small genus of ants in the subfamily Myrmicinae. Its two species are from Africa.
Secostruma is a genus of subterranean ants in the subfamily Myrmicinae containing the single species Secostruma lethifera. The genus is known from a single worker collected in Gunong Silam, Sabah, Malaysia.
Huberia is a genus of ants in the subfamily Myrmicinae. The genus contains two species endemic to New Zealand.
Lenomyrmex is a Neotropical genus of ant in the subfamily Myrmicinae.
Tyrannomyrmex is a rare tropical genus of ants in the subfamily Myrmicinae. Three similar species, only known from workers, are recognized and share small eyes and edentate mandibles.
Lophomyrmex is a genus of ants in the subfamily Myrmicinae. It is known from the Oriental and Indo-Australian regions.
Archimyrmex is an extinct genus of ant in the formicid subfamily Myrmeciinae, described by palaeoentomologist Theodore Cockerell in 1923. The genus contains four described species, Archimyrmex rostratus, Archimyrmex piatnitzkyi, Archimyrmex smekali and Archimyrmex wedmannae. Archimyrmex is known from a group of Middle Eocene fossils which were found in North America, South America, and Europe. The genus was initially placed in the subfamily Ponerinae, but it was later placed in Myrmeciinae; it is now believed to be the ancestor of the extant primitive genus Myrmecia from Australia. Despite this, Archimyrmex is not a member to any tribe and is regarded as incertae sedis within Myrmeciinae. However, some authors believe Archimyrmex should be assigned as incertae sedis within Formicidae. These ants can be characterised by their large mandibles and body length, ranging from 13.2 to 30 mm. They also have long, thin legs and an elongated mesosoma (thorax) and petiole.
