Prionomyrmecini
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. ''Not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prionomyrmex Longiceps Dorsal View Mbi5827d1
''Prionomyrmex'' is an extinct genus of bulldog ants in the subfamily Myrmeciinae of the family Formicidae. It was first described by Gustav Mayr in 1868, after he collected a holotype worker of ''P. longiceps'' in Baltic amber. Three species are currently described, characterised by their long mandibles, slender bodies and large size. These ants are known from the Eocene and Late Oligocene, with fossil specimens only found around Europe. It is suggested that these ants preferred to live in jungles, with one species assumed to be an arboreal nesting species. These ants had a powerful stinger that was used to subdue prey. In 2000, it was suggested by Cesare Baroni Urbani that the living species ''Nothomyrmecia macrops'' and a species he described both belonged to ''Prionomyrmex'', but this proposal has not been widely accepted by the entomological community. Instead, scientists still classify the two genera distinctive from each other, making ''Nothomyrmecia'' a valid genus. Dis ...

Nothomyrmecia Macrops
''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. As a medium-sized ant, ''Nothomyrmecia'' measures . Workers are mono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Myrmeciinae
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.

Poochera, South Australia
Poochera is a small grain belt town 60 km north-west of Streaky Bay on the Eyre Peninsula, South Australia. The township of Poochera was not surveyed until 1920, and its name is thought to be taken from the name of King Poojeri, a local aboriginal who died in 1917. A nearby hill is also named Poochera, possibly stemming from the same origin. The town had a school which opened in 1920, but closed its doors in 1976. Poochera is the centrepoint of a large agricultural area, the town itself being a strategic grain exchange point for the region's farmers, who specialise in cereal crops and sheep. The town is 53 km away from the Gawler Ranges, and is commonly used as a stop off by tourists, who have access to a hotel and caravan park. Poochera, however, is probably best noted for its nearby colonies of dinosaur ant ('' Nothomyrmecia macrops''), a rare, primitive species of ant that has attracted entomologists and evolutionary biologists from around the world.

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Great Australian Bight
The Great Australian Bight is a large oceanic bight, or open bay, off the central and western portions of the southern coastline of mainland Australia. Extent Two definitions of the extent are in use – one used by the International Hydrographic Organization (IHO) and the other used by the Australian Hydrographic Service (AHS). The IHO defines the Great Australian Bight as having the following limits: ''On the North.'' The south coast of the Australian mainland. ''On the South.'' A line joining West Cape Howe () Australia to South West Cape, Tasmania. ''On the East.'' A line from Cape Otway, Victoria to King Island and thence to Cape Grim, the northwest extreme of Tasmania. The AHS defines the bight with a smaller area, from Cape Pasley, Western Australia, to Cape Carnot, South Australia - a distance of . Much of the bight lies due south of the expansive Nullarbor Plain, which straddles South Australia and Western Australia. The Eyre Highway passes close to the cli ...

Balladonia, Western Australia
Balladonia is a small roadhouse community located on the Eyre Highway in Western Australia. It is the first stop east of Norseman on the journey east across the Nullarbor Plain. Between Balladonia and Caiguna is a stretch of the highway which is one of the longest straight stretches of road in the world. History The name is an Aboriginal word meaning "big rock by itself". The area was settled by Europeans in 1879, and the original Balladonia homestead was built away from the present townsite. From 1897 to 1929, Balladonia was a telegraph station on the East-West Telegraph, a telegraph line running from Perth to Adelaide telegraph line, due to a previous coastal line being shorted by salt spray from the Southern Ocean. The arid climate and lack of suitable water sources restricted the town's development. In July 1979, the area gained worldwide attention when the re-entry of the Skylab space station left a trail of debris across the nearby countryside. Balladonia Statio ...

Eucalyptus Oleosa
''Eucalyptus oleosa'', commonly known as the red mallee, glossy-leaved red mallee, acorn mallee, oil mallee or giant mallee, is a tree or mallee that is native to Australia. The leaves were once harvested for the production of cineole based eucalyptus oil. ''Eucalyptus cneorifolia'' is now the predominant strain used in production due to a higher oil content in new growth. Description ''Eucalyptus oleosa'' is a multi-stemmed tree or mallee that typically grows to a height of and has rough fibrous brown bark at the base that becomes smooth and grey above. It blooms between November and December producing yellow flowers. The adult leaves are around in length and wide. They have a narrow-lanceolate to lanceolate shape and are glossy and green in colour.
