Sphinctomyrmex is a genus of ants in the subfamily Dorylinae. [2] The genus is a tropical and distinctive group, originally described by Mayr based on a single gyne collected in Brazil. [3] Morphologically, the genus is characterized by the unique arrangement of the gastric segments, which are nearly equal in length and separated from each other by distinct constrictions. Very little is known on the natural history of Sphinctomyrmex. The few observations so far suggest that ants of this genus are nomadic predators of other ants. [3] The genus Zasphinctus and approximately 20 species were formerly included, but were split out during revision of the Dorylinae genera by Borowiec (2016). [4]
Dorylinae is an ant subfamily, with distributions in both the Old World and New World. Brady et al. (2014) synonymized the previous dorylomorph subfamilies under Dorylinae., while Borowiec (2016) reviewed and revised the genera, resurrecting many genera which had previously been merged. Dorylinae genera are suggested to have evolved sometime between 102 to 74 million years ago, subsequently undergoing rapid adaptive radiation events during their early history.
Amyrmex golbachi is a rare Neotropical species of ant and the only known species in the genus Amyrmex. It is currently only known from males from the Amazon basin of Brazil and from northern Argentina.
Leptomyrmex, or spider ants, is a genus of ants and a distinctive member of the ant subfamily Dolichoderinae. Commonly known as "spider ants" for their long legs and spider-like movements, these orange and black ants are prominent residents of intact wet forest and sclerophyll habitats throughout their range. One extant species, Leptomyrmex relictus, is known from central Brazil; otherwise, the global distribution of this genus is restricted to eastern Australia, New Caledonia and New Guinea, as well as the nearby Indonesian islands of Aru and Seram.
Ooceraea biroi, the clonal raider ant, is a queenless clonal ant in the genus Ooceraea. Native to the Asian mainland, this species has become invasive on tropical and subtropical islands throughout the world. Unlike most ants, which have reproductive queens and mostly nonreproductive workers, all individuals in a O. biroi colony reproduce clonally via thelytokous parthenogenesis. Like most dorylines, O. biroi are obligate myrmecophages and raid nests of other ant species to feed on the brood.
Leptanilloides is a genus of ants in the subfamily Dorylinae. Leptanilloides is an uncommonly collected genus with subterranean habits in the New World Andean and sub-Andean tropics.
Cerapachys is a genus of ants in the subfamily Dorylinae. Species are mainly myrmecophagous ants which raid the nests of other ants for prey. The genus is distributed widely throughout the Indomalayan region. The genus was revised by BoroWiec (2016) who split a number of previously synonymized genera out of Cerapachys, leaving only 5 species in the genus.
Lachnomyrmex is a Neotropical genus of ants in the subfamily Myrmicinae. The genus consists of 16 species restricted to the Neotropics, known from southern Mexico to northern Argentina. They are most often found in the leaf litter of wet forests, with nests located on the ground. Workers forage alone, apparently without recruiting nestmates or using pheromones. Within the tribe Stenammini, they seem to be most closely related to the genera Lordomyrma of Indo-Australia and Cyphoidris of Africa.
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.
Sphinctomyrmex stali is a Neotropical species of ants in the subfamily Dorylinae. Mayr described the genus Sphinctomyrmex with S. stali as its type species, based on a single dealate gyne. However, except for the holotype, there are no records of normal (alate) gynes for S. stali. All reproductive females collected after the original description are ergatoids.
Sphinctomyrmex schoerederi is a Neotropical species of ants in the subfamily Dorylinae. S. schoerederi is known only from the holotype, collected in a leaf litter sample from a forest remnant in the campus of Universidade Federal de Viçosa in Brazil, where it occurs in sympatry with S. stali. Gynes and males are unknown.
Zasphinctus is a genus of ants in the subfamily Dorylinae. The genus is a pantropical and distinctive group, originally described by Wheeler (1918) based on "Sphinctomyrmex" turneri collected in Queensland, Australia. Zasphinctus was first described as a subgenus of "Eusphinctus", and then synonymized into Sphinctomyrmex, to later be raised to full genus status by Borowiec (2016), who included approximately 20 species in the new genus circumscription.
Chrysapace is a genus of ants in the subfamily Dorylinae containing four described species. The genus is distributed across the Malaysian peninsula, Indonesia, and the Philippines, with undescribed species from Madagascar and from Baltic amber Chrysapace was described by Crawley (1924) and later placed as a junior synonym of Cerapachys by Brown (1975). Chrysapace was resurrected as a valid genus by Borowiec (2016) during redescription of the doryline genera.
Lioponera is a genus of ants in the subfamily Dorylinae containing approximately 74 described species. The genus is distributed widely across the Afrotropical, Australasia, Indomalaya, Malagasy, and Palearctic bioregions. Lioponera was described by Mayr (1879) and later placed as a junior synonym of Cerapachys by Brown (1975). Lioponera was resurrected as a valid genus by Borowiec (2016) during redescription of the doryline genera.
Ooceraea is a genus of ants in the subfamily Dorylinae containing approximately 16 described species. The genus is distributed across the Australasia, Indomalaya, Malagasy, Neotropical, Oceania, and Palearctic bioregions. Ooceraea was described by Roger (1862) and later placed as a junior synonym of Cerapachys by Brown (1973). Ooceraea was resurrected as a valid genus by Borowiec (2016) during redescription of the doryline genera.
Parasyscia is a genus of ants in the subfamily Dorylinae containing approximately 50 described species. The genus is distributed across the Afrotropical, Australasia, Indomalaya, Malagasy, Oceania, and Palearctic bioregions. Parasyscia was described by Emery (1882), moved to a subgenus of Cerapachys by Forel (1892) and finally placed as a junior synonym of Cerapachys by Kempf (1972). Parasyscia was resurrected as a valid genus by Borowiec (2016) during redescription of the doryline genera.
Syscia is a genus of ants in the subfamily Dorylinae containing thirty eight described species. The genus is distributed widely across the Eastern Asia, North America, and South America. Syscia was described by Roger (1861), later placed as a Cerapachys subgenus by Wheeler (1902) and then junior synonym of Cerapachys by Kempf (1972). Syscia was resurrected as a valid genus by Borowiec (2016) during redescription of the doryline genera.
Yunodorylus is a genus of ants in the subfamily Dorylinae containing four described species. The genus is distributed widely across mainland Southeast Asia and the island of Borneo. Yunodorylus was described in 2000, later placed as a junior synonym of Cerapachys by Bolton (2003), and was resurrected as a valid genus by Borowiec (2016)
Neocerapachys is a genus of ants in the subfamily Dorylinae containing 2 described species. The genus is distributed across the Neotropical bioregion in central and South America. Neocerapachys was described by Borowiec (2016) during redescription of the doryline genera.
