Barycheloides is a genus of South Pacific brushed trapdoor spiders first described by Robert Raven in 1994. [2]
As of April 2019 [update] it contains five species, all found on New Caledonia: [1]
Nursery web spiders (Pisauridae) is a family of araneomorph spiders first described by Eugène Simon in 1890. They resemble wolf spiders (Lycosidae) except for several key differences. Wolf spiders have two very prominent eyes in addition to the other six, while a nursery web spider's eyes are all about the same size. Additionally, female nursery web spiders carry their egg sacs with their jaws and pedipalps instead of attaching them to their spinnerets as wolf spiders do. When the eggs are about to hatch, a female spider builds a nursery "tent", places her egg sac inside, and stands guard outside, hence the family's common name. Like the wolf spiders, however, the nursery web spiders are roaming hunters that don't use webs for catching prey. They have a wide variety of prey, and larger species may prey upon vertebrates, particularly amphibians and fish.
Miturgidae is a family of araneomorph spiders that includes nearly 170 species in 29 genera worldwide. First described by Eugène Simon in 1886, it has been substantially revised, including of previous family "Zoridae" as subfamily "Zorinae" and excluding the family "Xenoctenidae". Several genera have also been removed, such as the large genus Cheiracanthium, which was transferred to the Cheiracanthiidae.
Nihoa is a genus of South Pacific brushed trapdoor spiders first described by Tracey Churchill & Robert Raven in 1992. It is named after the island Nihoa, where the type species is endemic.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera. Most spiders in this family build trapdoor burrows. For example, the 20 millimetres (0.79 in) long Sipalolasma builds its burrow in rotted wood, with a hinged trapdoor at each end. The 10 millimetres (0.39 in) long Idioctis builds its burrow approximately 5 centimetres (2.0 in) deep, just below the high tide level, sealing the opening with a thin trapdoor.
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.
Caledothele is a genus of South Pacific spiders in the family Euagridae. It was first described by Robert Raven in 1991.
Desis is a genus of intertidal spiders that was first described by Charles Athanase Walckenaer in 1837. It is found in Australasia, the Pacific, Japan, eastern and southern Africa, and India. They are truly marine spiders, living in the intertidal zone and only emerging at night on the ebb tide to hunt for invertebrates and small fish. In the day and during high tides, they hide in an air chamber sealed with silk.
Encyocrypta is a genus of South Pacific brushed trapdoor spiders first described by Eugène Simon in 1889.
Idioctis is a genus of brushed trapdoor spiders that was first described by L. Koch in 1874.
Mandjelia is a genus of South Pacific brushed trapdoor spiders first described by Robert Raven in 1994.
Natgeogia is a monotypic genus of South Pacific brushed trapdoor spiders containing the single species, Natgeogia rastellata. It was first described by Robert Raven in 1994, and has only been found on New Caledonia.
Orstom is a genus of South Pacific brushed trapdoor spiders first described by Robert Raven in 1994.
Questocrypta is a monotypic genus of South Pacific brushed trapdoor spiders containing the single species, Questocrypta goloboffi. It was first described by Robert Raven in 1994, and has only been found on New Caledonia.
Seqocrypta is a genus of Australian brushed trapdoor spiders first described by Robert Raven in 1994.
Tungari is a genus of Australian brushed trapdoor spiders first described by Robert Raven in 1994.
Poecilipta is a genus of South Pacific corinnid sac spiders first described by Eugène Simon in 1897.
Stenygrocercus is a genus of South Pacific spiders in the family Euagridae. It was first described by Eugène Simon in 1892.
Caledomedes is a genus of nursery web spiders containing the single species, Caledomedes flavovittatus. It was first described by Robert J. Raven & W. Hebron in 2018, and is only found in New Caledonia.
Moruga is a genus of Australian brushed trapdoor spiders first described by Robert J. Raven in 1994.
