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.
Myrmeciinae is a subfamily of the Formicidae, ants once found worldwide but now restricted to Australia and New Caledonia. This subfamily is one of several ant subfamilies which possess gamergates, female worker ants which are able to mate and reproduce, thus sustaining the colony after the loss of the queen. The Myrmeciinae subfamily was formerly composed of only one genus, Myrmecia, but the subfamily was redescribed by Ward & Brady in 2003 to include two tribes and four genera: An additional three genera, one form genus, and 9 species were described in 2006 from the Early Eocene of Denmark, Canada, and Washington. Subsequently an additional fossil genus was moved from the family Rhopalosomatidae in 2018, and a new genus was described in 2021.
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.
Plagiolepis is an ant genus of the formic acid-producing subfamily Formicinae. The genus is found in tropical and temperate regions of the Old World.
Eutetramorium is a small genus of ants within the subfamily Myrmicinae. To date it contains three species found in Madagascar and Comoros.
Sphecomyrminae is an extinct subfamily of ants in family Formicidae known from a series of Cretaceous fossils found in North America, Europe, and Asia. Sphecomyrminae contains eight genera, divided into two tribes Sphecomyrmini and Zigrasimeciini. The tribe Sphecomyrmini contains the six genera Armania, Cretomyrma, Gerontoformica, Orapia, Pseudarmania and Sphecomyrma; while Zigrasimeciini contains Boltonimecia and Zigrasimecia. A number of taxa have been removed from the subfamily and placed either in other subfamilies or are now treated as incertae sedis in Formicidae.
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.
Calyptomyrmex is a genus of ants in the subfamily Myrmicinae. The genus is distributed from Africa to India and east to New Caledonia. They are mainly found in the rainforest, where they forage alone or in small numbers.
Pristomyrmex is a genus of ants in the subfamily Myrmicinae.
Burmomyrma is an extinct genus of aculeate hymenopteran, suggested to be an ant. The genus contains a single described species, Burmomyrma rossi. Burmomyrma is known from a single Middle Cretaceous fossil which was found in Asia.
Afromyrma is an extinct genus of ant in the formicid subfamily Myrmicinae, and is currently unplaced in any of the tribes of that subfamily. The genus contains a single described species, Afromyrma petrosa. Afromyrma is known from a single Upper Cretaceous fossil, which was found in Orapa in the Central District of Botswana.
Usomyrma is an extinct genus of ant in the formicid subfamily Dolichoderinae. The genus contains a single described species, Usomyrma mirabilis, that is known from two Middle Eocene fossils which were found in Scandinavian amber in Denmark.
Zherichinius is an extinct genus of ants in the subfamily Dolichoderinae known from fossils found in amber from the Middle Eocene of Sakhalin island Far eastern Russia and Bitterfeld, Germany. At the time of description the species Zherichinius horribilis and Zherichinius rapax were two of eight ant species known from Sakhalin fossils.
Mayriella is an Indo-Australian genus of ants in the subfamily Myrmicinae. Colonies in this genus are very small, typically consisting of 50 - 100 individuals.
Aneuretellus is an extinct genus of ant in the formicid subfamily Aneuretinae, and is one of eight genera of the subfamily. The genus contains a single described species Aneuretellus deformis and is known from one Middle Eocene fossil which was found in Sakhalin in the Russian Far East.
Agastomyrma is an extinct genus of formicid in the ant subfamily Myrmicinae known from the fossil species Agastomyrma laticeps found in eastern Asia.
Aphaenogaster dlusskyana is an extinct species of ant in the subfamily Myrmicinae known from a single Middle Eocene fossil found in amber on Sakhalin. At the time of description A. dlusskyana was one of eight ant species known from Sakhalin fossil.
Manica andrannae is a fossil species of the ants tribe Myrmicini from the subfamily Myrmicinae (Formicidae). It was discovered in Europe. Eocene amber has been dated at 33.9–37.8 million years ago. This is the first finding of this genus in a fossil state, having a plesiomorphic state with features such as the propodeum having a weakly convex dorsum and short, blunt tubercles, and by a more angular petiolar node.
