Myrmecia imaii is a species of ant in the genus Myrmecia . Described by Robert Taylor in 2015, the species is endemic to Australia in Western Australia, particularly in very south-western areas. [1]
Myrmecia is a genus of ants first established by Danish zoologist Johan Christian Fabricius in 1804. The genus is a member of the subfamily Myrmeciinae of the family Formicidae. Myrmecia is a large genus of ants, comprising at least 93 species that are found throughout Australia and its coastal islands, while a single species is only known from New Caledonia. One species has been introduced out of its natural distribution and was found in New Zealand in 1940, but the ant was last seen in 1981. These ants are commonly known as bull ants, bulldog ants or jack jumper ants, and are also associated with many other common names. They are characterized by their extreme aggressiveness, ferocity, and painful stings. Some species are known for the jumping behavior they exhibit when agitated.
The jack jumper ant, also known as the jack jumper, jumping jack, hopper ant, or jumper ant, is a species of venomous ant native to Australia. Most frequently found in Tasmania and southeast mainland Australia, it is a member of the genus Myrmecia, subfamily Myrmeciinae, and was formally described and named by British entomologist Frederick Smith in 1858. This species is known for its ability to jump long distances. These ants are large; workers and males are about the same size: 12 to 14 mm for workers, and 11 to 12 mm for males. The queen measures roughly 14 to 16 mm long and is similar in appearance to workers, whereas males are identifiable by their perceptibly smaller mandibles.
Nothomyrmecia, also known as the dinosaur ant or dawn ant, is an extremely rare genus of ants consisting of a single species, Nothomyrmecia macrops. These ants live in South Australia, nesting in old-growth mallee woodland and Eucalyptus woodland. The full distribution of Nothomyrmecia has never been assessed, and it is unknown how widespread the species truly is; its potential range may be wider if it does favour old-growth mallee woodland. Possible threats to its survival include habitat destruction and climate change. Nothomyrmecia is most active when it is cold because workers encounter fewer competitors and predators such as Camponotus and Iridomyrmex, and it also increases hunting success. Thus, the increase of temperature may prevent them from foraging and very few areas would be suitable for the ant to live in. As a result, the IUCN lists the ant as Critically Endangered.
Myrmecia forficata, commonly known as the inchman ant, is a species of bull ant that is native to Australia. The ants are recorded in the south eastern part of the country, but are most common in the Australian Alps at elevations above 300m but can be found down to sea level around Melbourne and in Tasmania.
Myrmecia inquilina is a species of ant endemic to Australia in the subfamily Myrmeciinae, first discovered in 1955 and described by Athol Douglas and William Brown Jr. in 1959. These ants are large, measuring 21.4 millimetres (0.84 in). During the time of its discovery, Douglas and Brown announced M. inquilina as the first social parasite among the primitive subfamilies, and today it is one of the two known Myrmecia species to have no worker caste. Two host species are known, Myrmecia nigriceps and Myrmecia vindex. Aggression between M. inquilina and its host species does not occur, and colonies may only produce M. inquilina brood months after the inquiline queens begin to lay their eggs. Queens eat the colony brood or trophic eggs, and other Myrmecia species may kill M. inquilina queens if they reject them. Due to its restricted distribution and threats to its habitat, the ant is "vulnerable" according to the IUCN Red List.
Myrmecia nigriceps, also known as the black-headed bull ant, is a species of ant endemic to Australia. A member of the genus Myrmecia in the subfamily Myrmeciinae, it was first described by Austrian entomologist Gustav Mayr in 1862. These ants are large, varying from 19 to 23 millimetres in length. However, colonies contain workers that are much smaller, usually half the size of normal workers. The queens are the largest while the males are the smallest, which can be easily identified due to their small mandibles.
Myrmecia croslandi is a species of bull ant which is endemic to Australia. Myrmecia croslandi is a jumping type of bull ant, which means it could be called a jack jumper. Myrmecia croslandi are located around Australia. They can be seen throughout New South Wales and Queensland. Myrmecia croslandi was described by Taylor in 1991.
Prionomyrmecini is an ant tribe belonging to the subfamily Myrmeciinae established by William Morton Wheeler in 1915. Two members are a part of this tribe, the extant Nothomyrmecia and the extinct Prionomyrmex. The tribe was once considered a subfamily due to the similarities between Nothomyrmecia and Prionomyrmex, but such reclassification was not widely accepted by the scientific community. These ants can be identified by their long slender bodies, powerful stingers and elongated mandibles. Fossil Prionomyrmecini ants were once found throughout Europe, possibly nesting in trees and preferring jungle habitats. Today, Prionomyrmecini is only found in Australia, preferring old-growth mallee woodland surrounded by Eucalyptus trees. Nothomyrmecia workers feed on nectar and arthropods, using their compound eyes for prey and navigational purposes. Owing to their primitive nature, they do not recruit others to food sources or create pheromone trails. Nothomyrmecia colonies are small, consisting of 50 to 100 individuals.
Myrmecia vindex is a species of Myrmecia which is endemic to Australia. As a subgroup of the Myrmecia gulosa species group, these ants are also commonly known as the Bull Ant. The Myrmecia vindex was collected and described by Frederick Smith in 1858.
Myrmecia pyriformis, also known as the bull ant or inch ant, is an Australian ant. Myrmecia pyriformis belongs to the genus Myrmecia. It is abundant in many major cities of Australia, but mostly spotted in the eastern states. The species is of a similar appearance to the Myrmecia forficata.
Myrmecia nigrocincta, commonly known as the jumper ant or jumping jack, is an ant of the genus Myrmecia. The species was first described by Frederick Smith in 1858. Colonies of this ant are abundant in eastern Australia. Ants of this species are known for their ability to jump up to 10 centimetres, and they also have a powerful, venomous sting. Rather than foraging on the ground, M. nigrocincta prefer to forage in trees where they are known to pollinate certain flowers.
Myrmecia fulgida is an Australian ant which belongs to the genus Myrmecia. This species is native to Australia. Their distribution mostly in Western Australia and some areas of the east of Australia.
Myrmecia regularis is a species of ant endemic to Australia. A member of the genus Myrmecia in the subfamily Myrmeciinae, it was first described by American entomologist Walter Cecil Crawley in 1925. These ants are medium to large in size, measuring 10 to 20 millimetres, and they are bright brownish-red in colour. Queens and workers share similar morphological features, but they can be distinguished by the noticeable size difference. Males also look similar, but collected specimens are too damaged to be examined properly.
Myrmecia tridentata is an Australian ant which belongs to the genus Myrmecia. It is native to Australia. They have been usually spotted in South Australia, Victoria, and Queensland. It was described by Kazuo Ogata and Robert Taylor in 1991.
Myrmecia maxima is an unidentifiable species of ant endemic to Australia. A member of the genus Myrmecia in the subfamily Myrmeciinae, M. maxima was first described by George Fletcher Moore in 1842. As no type specimen is available, M. maxima cannot be confidently identified, but the only description Moore had provided undoubtedly describes a large Myrmecia species, having long, sharp mandibles and a formidable sting. It is still classified as a valid species. The ant resides in the south-west regions of Western Australia. As other Myrmecia species have been identified in these regions, M. maxima is possibly a senior synonym of one of these ants. Its former name is recognised as an invalid name after it was suppressed under plenary powers in 1976.
Myrmecia banksi is a species of ant in the genus Myrmecia. Described by Robert Taylor in 2015, the species is endemic to Australia in New South Wales, where it is normally found on low elevations along coastal regions.
Myrmecia haskinsorum is a species of ant in the genus Myrmecia. Described by Robert Taylor in 2015, the species is endemic to Australia where it is known from areas that have high elevations, although some records show the ant lives in low elevated areas in Tasmania
Myrmecia impaternata is a species of gynogenetic, female-only ant in the genus Myrmecia. Described by Robert Taylor in 2015, the species is endemic to Australia and is common in Canberra and around Armidale. Observations of the species have been confirmed in Queensland.
