Stigmacros is an Australian genus of small ants in the subfamily Formicinae. [2] The genus is endemic to Australia. They are generalist predators that forage in the leaf litter, on the ground or in trees. [3]
Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the largest country in Oceania and the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia, and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. The population of 26 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia's capital is Canberra, and its largest city is Sydney. The country's other major metropolitan areas are Melbourne, Brisbane, Perth, and Adelaide.
A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 140 million years ago, and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development.
Anonychomyrma is a genus of ants in the subfamily Dolichoderinae.
Aphaenogaster is a genus of myrmicine ants. About 200 species have been described, including 18 fossil species. They occur worldwide except in South America south of Colombia, Sub-Saharan Africa, and Antarctica.
Cardiocondyla is an Old World genus of ants in the subfamily Myrmicinae.
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.
Tetramorium is a genus of ants in the subfamily Myrmicinae that includes more than 520 species.
Crematogastrini is a tribe of myrmicine ants with 64 genera and 8 fossil genera.
Myopias is a genus of ants in the subfamily Ponerinae. The genus is known from the Oriental, Indo-Australian, and Australasian regions.
Rhytidoponera is a large genus of ants in the subfamily Ectatomminae. The genus is known from Australia and Melanesia, with New Caledonia as the most eastern limit.
Technomyrmex is a genus of ants in the subfamily Dolichoderinae. With 98 species, it is one of the largest and most diverse ant genera in the Dolichoderinae. The genus distributed throughout the tropical and subtropical zones with most species occurring in the Oriental-Malesian and Afrotropical regions. One species, Technomyrmex albipes is a tramp ant now widespread throughout the tropics due to human activities.
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 tropical and subtropical regions of the world, with the majority of species known from the Indo-Australian region.
Epopostruma is a genus of ants in the subfamily Myrmicinae. It is restricted to Australia.
Podomyrma is a genus of ants in the subfamily Myrmicinae.
Meranoplus is an Old World genus of ants in the subfamily Myrmicinae. With over 80 valid species, it is predicted that over half of the Meranoplus diversity remains undescribed, most of these from Australia.
Melophorus is a genus of ants in the subfamily Formicinae and the sole member of the tribe Melophorini. The genus is endemic to Australia, where its species are common in arid and semiarid areas.
Prolasius is a genus of ants in the subfamily Formicinae. Of the genus' 19 species, 18 are known from Australia and one from New Zealand. They nest in soil under rocks or logs, sometimes in trees.
Pseudolasius is a genus of ants in the subfamily Formicinae. The genus is known from southern Asia to northern Australia, where it appears to be restricted to tropical areas.
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.
