Orstom is a genus of South Pacific brushed trapdoor spiders first described by Robert Raven in 1994. [2]
As of April 2019 [update] it contains six species, all found in 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.
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.
Synothele is a genus of Australian brushed trapdoor spiders first described by Eugène Simon in 1908. The number of species in the genera was greatly expanded by Robert Raven in 1994.
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.
Barycheloides is a genus of South Pacific brushed trapdoor spiders first described by Robert Raven in 1994.
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.
Ozicrypta is a genus of Australian 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.
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.
Philippe Morat is a researcher mainly in the field of tropical botany. He is a corresponding member of the French Academy of Sciences.
Mandjelia anzses is a species of mygalomorph spider in the Barychelidae family. It is endemic to Australia. It was described in 1994 by Australian arachnologists Robert Raven and Tracey Churchill. The specific epithet anzes honours the participants in the expedition of the Australian and New Zealand Scientific Exploration Society (ANZSES).
Mandjelia platnicki is a species of mygalomorph spider in the Barychelidae family. It is endemic to New Caledonia. It was described in 1994 by Australian arachnologist Robert Raven. The specific epithet platnicki honours Dr Norman I. Platnick, Chairman of the Entomology Department at the American Museum of Natural History, for his contributions to arachnology.
