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.
Adetomyrma venatrix, more commonly known as the Dracula ant, so named because of its grisly feeding habits of drinking the blood of its young, is an endangered species of ants endemic to Madagascar. Workers of this species are blind. The species was described as the type species of Adetomyrma in 1994, with the genus being an atypical member of its tribe.
Amblyopone is a genus of 10 species of ants, found in Australia, New Caledonia, New Guinea and New Zealand. Ants of this genus possess the gamergate, meaning workers are able to reproduce within a colony lacking a queen.
Apomyrma stygia is a species of ant found in West Africa, first described in 1970. It is the only species in the genus Apomyrma, tribe Apomyrmini, and subfamily Apomyrminae. It has been suggested the ant primarily lives in tropical forests, and apparently belongs to a guild of centipede-feeding ants.
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.
A gamergate is a mated worker ant that can reproduce sexually, i.e., lay fertilized eggs that will develop as females. In the vast majority of ant species, workers are sterile and gamergates are restricted to taxa where the workers have a functional sperm reservoir ('spermatheca'). In some species, gamergates reproduce in addition to winged queens, while in other species the queen caste has been completely replaced by gamergates. In gamergate species, all workers in a colony have similar reproductive potentials, but as a result of physical interactions, a dominance hierarchy is formed and only one or a few top-ranking workers can mate and produce eggs. Subsequently however, aggression is no longer needed as gamergates secrete chemical signals that inform the other workers of their reproductive status in the colony.
Amblyoponinae is a subfamily of ants in the poneromorph subfamilies group containing 13 extant genera and one extinct genus. The ants in this subfamily are mostly specialized subterranean predators. Adult workers pierce the integument of their larvae and pupa to imbibe haemolymph, earning them the common name Dracula ant.
Stigmatomma is a genus of ants in the subfamily Amblyoponinae. The genus has a worldwide distribution, and like most other amblyoponines, Stigmatomma species are specialized predators. First described by Roger (1859), it was for a long time considered to be a synonym of Amblyopone until it was revived as an independent genus by Yoshimura & Fisher (2012) based on worker mandible morphology.
Mystrium is a rare genus of ants in the subfamily Amblyoponinae. First described by Roger (1862) with the description of the queen of M. mysticum, the genus contains 14 species, all of which occur in the rainforests of the Old World with over half of the species endemic to the Malagasy region.
Xymmer is a genus of ant in the subfamily Amblyoponinae containing the single species Xymmer muticus.
Onychomyrmex is an Australian genus of ants in the subfamily Amblyoponinae. Its three species are known from eastern Queensland, Australia. Although not true army ants, Onychomyrmex species display an army-ant life style, including group predation and nomadism.
Stigmatomma mulanae is a species of ant of the genus Stigmatomma. Described by Xu in 2000 from a single dealate queen found in 1998 in the Xishuangbanna Nature Reserve in Yunnan Province, it was placed as the type species of Bannapone, under the name Bannapone mulanae. It was moved to Stigmatomma by Ward & Fisher (2016).
Fulakora is a genus of ants in the subfamily Amblyoponinae. The genus has a worldwide distribution, and like most other amblyoponines, Fulakora species are specialized predators. It was originally described as, and for a long time considered to be, a subgenus of Stigmatomma until it was elevated to an independent genus by Ward & Fisher (2016).
Stigmatomma scrobiceps is a species of ant in the genus Stigmatomma. It was described as Bannapone scrobiceps by Guénard et al. in 2013, based on two specimens collected in Yunnan Province, China, and placed as the second species in Bannapone. It was moved to Stigmatomma by Ward & Fisher (2016).
Casaleia is an extinct genus of ants in the formicid subfamily Amblyoponinae described by Pagliano & Scaramozzino in 1990 from fossils found in Europe. The genus contains four species dating from the Eocene to Miocene, Casaleia eocenica, Casaleia inversa, Casaleia longiventris, Casaleia orientalis.
Stigmatomma electrinum is an extinct species of ant in the genus Stigmatomma. It was described in 2009 after fossils were found in the Baltic Amber.
Stigmatomma groehni is an extinct species of ant in the genus Stigmatomma. It was described by Dlussky in 2009, where it was found in the Baltic Amber, alongside another extinct species Stigmatomma electrinum.
Stigmatomma trigonignathum is a species of ant in the subfamily Amblyoponinae. It is considered one of the rarest ants in the world, only known from one specimen collected in 1948 and another observed in 2008. Both records are from the Piedmont region of North Carolina.
