Chenistonia earthwatchorum is a species of mygalomorph spider in the Anamidae family. It is endemic to Australia. It was described in 1984 by Australian arachnologist Robert Raven. [1] [2]
The species occurs in Queensland. [2]
A raven is any of several larger-bodied passerine bird species in the genus Corvus. These species do not form a single taxonomic group within the genus. There is no consistent distinction between "crows" and "ravens", common names which are assigned to different species chiefly based on their size.
The Australian raven is a passerine bird in the genus Corvus native to much of southern and northeastern Australia. Measuring 46–53 centimetres (18–21 in) in length, it has all-black plumage, beak and mouth, as well as strong grey-black legs and feet. The upperparts are glossy, with a purple, blue, or green sheen, and its black feathers have grey bases. The Australian raven is distinguished from the Australian crow species by its throat hackles, which are prominent in adult birds. Older adult individuals have white irises, younger adults have white irises with an inner blue rim, while younger birds have dark brown irises until fifteen months of age, and hazel irises with an inner blue rim around each pupil until age two years and ten months. Nicholas Aylward Vigors and Thomas Horsfield described the Australian raven in 1827, its species name (coronoides) highlighting its similarity with the carrion crow. Two subspecies are recognized, which differ slightly in calls and are quite divergent genetically.
The forest raven, also commonly known as the Tasmanian raven, is a passerine bird in the family Corvidae native to Tasmania and parts of southern Victoria, such as Wilsons Promontory and Portland. Populations are also found in parts of New South Wales, including Dorrigo and Armidale. Measuring 50–53 cm (20–21 in) in length, it has all-black plumage, beak and legs. As with the other two species of raven in Australia, its black feathers have grey bases. Adults have white irises; younger birds have dark brown and then hazel irises with an inner blue rim. New South Wales populations are recognised as a separate subspecies C. tasmanicus boreus, but appear to be nested within the Tasmanian subspecies genetically.
The little raven is a species of the family Corvidae that is native to southeastern Australia. An adult individual is about 48–50 cm (19–19.5 in) in length, with completely black plumage, beak, and legs; as with all Australian species of Corvus, the black feathers have a grey base, and the iris of the adult bird is white . Although the little raven was first named by Gregory Mathews in 1912, it was only in 1967 that there was consensus to separate it from the Australian raven as a distinct species.
The family Dipluridae, known as curtain-web spiders are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that move up and down in a stabbing motion. A number of genera, including that of the Sydney funnel-web spider (Atrax), used to be classified in this family but have now been moved to Hexathelidae.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera.
Migidae, also known as tree trapdoor spiders, is a family of spiders with about 100 species in eleven genera. They are small to large spiders with little to no hair and build burrows with a trapdoor. Some species live in tree fern stems. They have a Gondwanan distribution, found almost exclusively on the Southern Hemisphere, occurring in South America, Africa, Madagascar, Australia, New Zealand and New Caledonia.
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.
Cethegus is a genus of Australian spiders in the family Euagridae. It was first described by Tamerlan Thorell in 1881.
Chenistonia caeruleomontana is a ground spider, found in New South Wales, Australia. Spiders in this group are called "wishbone spiders", for the shape of their open silk-lined burrow, which has the shape of the letter "Y", with one arm shorter than the other. Only the longer arm reaches the surface. The shorter arm is believed to allow the spider to survive flooding by trapping an air bubble.
Australothele is a genus of Australian spiders in the family Euagridae. It was first described by Robert Raven in 1984.
Namirea is a genus of Australian spiders in the family Euagridae. It was first described by Robert Raven in 1984.
Chenistonia is a genus of spiders in the family Anamidae. It was first described in 1901 by Henry Roughton Hogg. As of 2020, it contains 8 species, all from Australia.
Namea is a genus of spiders in the family Anamidae. It is endemic to Australia. It was first described in 1984 by Australian arachnologist Robert Raven. As of 2017, it contains 19 species, all from the states of Queensland (QLD) or New South Wales (NSW).
Chenistonia tropica is a species of mygalomorph spider in the Anamidae family. It is endemic to Australia. It was described in 1984 by Australian arachnologist Robert Raven.
Chenistonia hickmani is a species of mygalomorph spider in the Anamidae family. It is endemic to Australia. It was described in 1984 by Australian arachnologist Robert Raven.
Chenistonia montana is a species of mygalomorph spider in the Anamidae family. It is endemic to Australia. It was described in 1984 by Australian arachnologist Robert Raven.
Chenistonia trevallynia is a species of mygalomorph spider in the Anamidae family. It is endemic to Australia. It was described in 1926 by Australian arachnologist Vernon Victor Hickman.
Chenistonia maculata is a species of mygalomorph spider in the Anamidae family. It is endemic to Australia. It was described in 1901 by British arachnologist Henry Roughton Hogg.
Chenistonia boranup is a species of mygalomorph spider in the Anamidae family. It is endemic to Australia. It was described in 2012 by Australian arachnologist Barbara York Main.
