Miomyrmex is an extinct genus of ant of the subfamily Dolichoderinae. The fossils were first discovered in the United States in the state of Colorado in 1930. [1]
There are two species in this extinct genus. [2]
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.
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.
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.
Burmomyrma is an extinct genus of ant-mimic wasp in the extinct family Falsiformicidae. The genus contains a single described species, Burmomyrma rossi. Burmomyrma is known from a single Middle Cretaceous fossil which was found in Asia.
Pogonomyrmex fossilis is an extinct ant species which lived during the Eocene 34 million years ago. The species built nests primarily destined to store seeds and grains as winter stock. The ant has an average length of six millimeter and an average width of 1.2 millimeters.
Elaeomyrmex is an extinct genus of ant in the subfamily Dolichoderinae and containing two species. The fossils were first described from the Florissant Formation, Colorado in 1930.
Eotapinoma is an extinct genus of ants of the subfamily Dolichoderinae. It was described by Dlussky in 1988.
Kotshkorkia is an extinct genus of ants of the subfamily Dolichoderinae. The genus contains a single described species Kotshkorkia laticeps. It was described by Dlussky in 1981, where the first fossils of the ant were found in Russia.
Ctenobethylus is an extinct genus of ants in the subfamily Dolichoderinae. The genus contains a single described species Ctenobethylus goepperti, where the fossil is known to be from the Baltic Amber. The fossil contained a preserved mesostigmatid mite attached to the head of the ant, which is perhaps the oldest known evidence of ecological association between mites and ants.
Petraeomyrmex is a genus of extinct species in the subfamily Dolichoderinae. The genus only contains a single species Petraeomyrmex minimus. The species was once endemic to the United States in Colorado, which was the location of where the fossil remains were found.
Protazteca is an extinct genus of ants in the subfamily Dolichoderinae, that were endemic to the United States, which was described by Carpenter in 1930.
Iridomyrmex florissantius is an extinct species of ant in the genus Iridomyrmex. It was described by Carpenter in 1930 after a fossil was found in the United States.
Iridomyrmex obscurans is an extinct species of ant in the genus Iridomyrmex. Described by Frank Carpenter in 1930, the fossil was discovered in the United States, but unfortunately nothing much is known about this ant.
Dolichoderus antiquus is an extinct species of ant in the genus Dolichoderus. Described by Carpenter in 1930, the fossils of this species are only exclusive to the Florissant Formation.
Ponerini is a tribe of Ponerinae ants with 46 genera and 6 extinct genera.
Dolichoderus rohweri is an extinct species of ant in the genus Dolichoderus. Described by Carpenter in 1930, the fossils of this species are only found in the Florissant Formation, Colorado.
Liometopum miocenicum is an extinct species of ant in the genus Liometopum. Described by Carpenter in 1930, the fossils of this species are only exclusive to the United States.
Liometopum scudderi is an extinct species of ant in the genus Liometopum. Described by Carpenter in 1930, the fossils of this species are only exclusive to the United States.
