Aname diversicolor, the black wishbone spider, is a species of burrowing arachnid found in southern Australia.
A diplurine spider, family Anamidae, of the mygalomorphs. The colour in mainly black, sometimes bluish on the underside, Legs are long. Lateral margins are rounded at the broad carapace, which is at least 6.5 and greater than 10 millimetres in length. They are most readily diagnosed by the form of its burrow, the non-surfacing annex is close to the entry; tightly woven silk lines this Y–shape and the annex may formed immediately next to the entry. The habit of the sexually matured males to roam in humid and sudden summer storms on the Swan Coastal Plain is also observed as a characteristic of this species. [2]
They are widespread in their distribution range, although rarely abundant. Males are encountered in urban environs during humid weather in summer, as this induces them to wander, but they are mostly sedentary and remain within their silk-lined accommodation. [2] Observation of the aggressive, large and black individuals is often mistaken as a dangerous and unrelated species of funnel-web spider genus Atrax , [2]
Only one arm of the burrow reaches the surface, the other may function as a refuge for the spider if inundated by flooding. [2]
The species was first described as Dekana diversicolor by Henry Roughton Hogg in 1902. It was later assigned to the genus Aname , [1] all of which are endemic to Australia, on the basis of morphological characters. The type locality of this description was given as "Deka Station", which the revising author was unable to locate, the type specimen was also unavailable. The second part of the location was recorded by Hogg as "Blackhall", and Main indicates this may have been a misspelling of the location Blackall in western Queensland. A new specimen was collected near Elliston, South Australia and this was assigned as the neotype for the species. [2]
They display a characteristic of a group the arachnologist Barbara York Main referred to as 'wishbone spiders', for the 'Y' or wishbone-shape of their burrows. This characteristic amongst some genera of Australian mygalomorph genera was regarded as convergent, rather than indicating a monophyletic alliance. [2]
Atracidae is a family of mygalomorph spiders, commonly known as Australian funnel-web spiders or atracids. It has been included as a subfamily of the Hexathelidae, but is now recognized as a separate family. All members of the family are native to Australia. Atracidae consists of three genera: Atrax, Hadronyche, and Illawarra, comprising 35 species. Some members of the family produce venom that is dangerous to humans, and bites by spiders of six of the species have caused severe injuries to victims. The bites of the Sydney funnel-web spider and northern tree-dwelling funnel-web spider are potentially deadly, but no fatalities have occurred since the introduction of modern first-aid techniques and antivenom.
Atypidae, also known as atypical tarantulas or purseweb spiders, is a spider family containing only three genera. They are accomplished ambush predators that spend most of their time in a sock-like, silken retreat on the ground from where they kill their prey.
The Sydney funnel-web spider is a species of venomous mygalomorph spider native to eastern Australia, usually found within a 100 km (62 mi) radius of Sydney. It is a member of a group of spiders known as Australian funnel-web spiders. Its bite is capable of causing serious illness or death in humans if left untreated.
Atrax is a genus of venomous Australian funnel web spiders that was first described by O. Pickard-Cambridge in 1877 from the type species Atrax robustus. As of May 2019 it contains only three species: A. robustus, A. sutherlandi, and A. yorkmainorum. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980, then to the Australian funnel-web spiders in 2018.
Hadronyche is a genus of venomous Australian funnel-web spiders that was first described by L. Koch in 1873. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980, then to the Atracidae in 2018.
Idiopidae, also known as armored trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889. They have a large body similar to tarantulas.
Nemesiidae, also known as funnel-web trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae".
Idiosoma is a genus of Australian armoured trapdoor spiders that was first described by Anton Ausserer in 1871. Originally placed with the Ctenizidae, it was moved to the armoured trapdoor spiders in 1985. The name is derived from the Greek ἴδιος, meaning "individual, unique", and σῶμα, meaning "body", referring to the distinctive structure of the abdomen.
Aname is a genus of mygalomorph spiders. It is endemic to Australia. The spiders, as well as some in closely related genera, are also known as wishbone spiders.
Aname atra, the black wishbone spider, is a mygalomorph spider of South Australia. It is one of the wishbone spiders in the taxonomic family Anamidae, found in varied habitats throughout Australia, including Tasmania. The most common species are the mottled eastern wishbones in the genus Namea, found in rainforests, black wishbones in the genus Aname, found in drier parts of Queensland, and the bearded wishbone, Xamiatus magnificus, also found in Queensland.
Stanwellia is a genus of South Pacific mygalomorph spiders in the family Pycnothelidae. It was first described by W. J. Rainbow & R. H. Pulleine in 1918. Originally placed with the curtain-web spiders, it was transferred to the funnel-web trapdoor spiders in 1985, then to the Pycnothelidae in 2020. It is a senior synonym of Aparua.
Stanwellia grisea, also known as the Melbourne trapdoor spider, is a species of mygalomorph spider in the Pycnothelidae family. It is endemic to Australia. It was described in 1901 by British arachnologist Henry Roughton Hogg.
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of August 2022, 1,040 species have been identified, with 156 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.
Eucteniza is a genus of trapdoor spiders in the family Euctenizidae containing at least 14 species occurring in Mexico and the southern United States. Species are distinguished by a softened rear portion of the carapace, and males possess large spines on the first two pairs of walking legs that are used to hold females during mating. Like other trapdoor spiders they create burrows with a hinged lid, from which they await passing insects and other arthropods to prey upon. Many species are known from only one or two localities, or from only male specimens. More species are expected to be discovered. Eucteniza is closely related to spiders of the genera Entychides and Neoapachella.
Cantuaria dendyi is a species of trapdoor spider in the family Idiopidae. It can be found in the South Island of New Zealand and is limited to the Christchurch and Banks Peninsula area.
Hypochilus thorelli is a species of spider in the family Hypochilidae. Unlike almost all other araneomorph or "true" spiders, members of the family have four book lungs. They are often called "lampshade spiders" because of the shape of their webs which are usually built underneath ledges or projections. H. thorelli is found in the southern Appalachian Mountains of the eastern United States.
Kwonkan is a genus of Australian mygalomorph spiders first described by Barbara York Main in 1983. It was originally assigned to Dipluridae, but was later assigned to Nemesiidae due to similarities to the genus Aname, before being transferred to the family Anamidae in 2010. The known distribution of described species in the genus is restricted to the states of South Australia (SA) and Western Australia (WA). Yilgarnia is now considered a synonym for this genus, and its type species is assigned to Kwonkan currycomboides.
Anamidae is a family of Australian mygalomorph spiders. It was first described as a tribe by Simon in 1889, then raised to the subfamily Anaminae of the family Nemesiidae, before being raised to a family level by Opatova et al. in 2020.
Stanwellia occidentalis is a species of mygalomorph spider in the Pycnothelidae family. It is endemic to Australia. It was described in 1972 by Australian arachnologist Barbara York Main.
Stanwellia inornata is a species of mygalomorph spider in the Pycnothelidae family. It is endemic to Australia. It was described in 1972 by Australian arachnologist Barbara York Main.
