Dolomedidae
Dolomedidae is a family of spiders comprising seven genera formerly part of the family Pisauridae. It includes the genus '' Dolomedes'', known commonly as raft spiders, and its close relatives. Taxonomy The family was first circumscribed by Eugène Simon in 1876, but was later made synonymous with Pisauridae and Bradystichidae. It was restored to family level and redefined in 2025 based on a phylogenetic study of Pisauridae that found the family to be paraphyletic. Morphologically, they differ from pisaurids in possessing a subterminal lateral apophysis below the fulcrum in males, and in females by possessing small, rounded accessory bulbs. Genera it contains 7 genera: *'' Bradystichus'' Simon, 1884 - New Caledonia *'' Caledomedes'' Raven & Hebron, 2018 - New Caledonia *'' Dolomedes'' Latreille, 1804 - Europe, Africa, Oceania, South America, North America, Asia, Cuba *'' Mangromedes'' Raven, 2018 - Australia Australia, officially the Commonwealth of Australia, is a ...

Tasmomedes
''Tasmomedes'' is a monotypic genus of spiders in the family Dolomedidae containing only the species ''Tasmomedes eberhardarum''. It is endemic to Australia, where it occurs in Victoria and Tasmania. Taxonomy ''Dolomedes eberhardarum'' was described by Embrik Strand in 1913 based on a male type specimen collected in Victoria. In a 2018 review of the family Pisauridae, Robert Raven erected the new genus ''Tasmomedes'' for this species, combining it as ''Tasmomedes eberhardarum''. It is the only species in the genus. The name ''Tasmomedes'' is a combination of the words Tasmania and ''Dolomedes'', referring to the former placement of ''T. eberhardarum'' in ''Dolomedes'' and to its presence on the island of Tasmania. The type specimen is stored in the collection of the Museum Wiesbaden in Germany. ''Tasmomedes'' was placed in the family Pisauridae upon its initial description, but would be transferred to the family Dolomedidae in 2025. Distribution and habitat ''Tasmomedes eberhar ...

Ornodolomedes
''Ornodolomedes'', commonly known as rainforest sprites, is a genus of Australian spiders in the family Dolomedidae. The genus and its ten known species were described by Robert Raven & Wendy Hebron in 2018. Taxonomy The genus ''Ornodolomedes'' was described by Australian arachnologists Robert Raven and Wendy Hebron in a 2018 review of the family Pisauridae. The name ''Ornodolomedes'' is a combination of the words ornate and ''Dolomedes''. Ten newly described species were placed in the genus upon its description, with '' Ornodolomedes benrevelli'' designated as the type species. ''Ornodolomedes'' was placed in the family Pisauridae upon its initial description, but would be transferred to the family Dolomedidae in 2025. Distribution and habitat ''Ornodolomedes'' species are known from the Australian states of Queensland, New South Wales, South Australia, Victoria, and Western Australia. They are arboreal and can be found on bark and leaves in rainforests, vine thickets, and riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dolomedes Fimbriatus
The raft spider, scientific name ''Dolomedes fimbriatus'', is a large semi-aquatic spider of the family Dolomedidae found throughout north-western and central Europe. It is one of only two species of the genus ''Dolomedes'' found in Europe, the other being the slightly larger ''Dolomedes'' ''plantarius'' which is endangered in the UK. Habitat and description Raft spiders are semi-aquatic and adults inhabit freshwater wetlands, specifically wet heaths and acid swamps; although juveniles are predominantly found in terrestrial vegetation surrounding wetland areas. Adults are dark brown with a conspicuous white, cream or yellow stripe along both sides of their abdomen and thorax. Juveniles are similar in appearance but often have green translucent legs. As is common in other spiders, female raft spiders (body length: 9–22mm) are usually larger than males (body length (9-15mm). Dolomedes fimbriatus was described in chapter 5 of the book ''Svenska Spindlar'' by the Swedish arachn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araneomorphae
The Araneomorphae (also called the Labidognatha or "true spiders") are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority (about 93%) of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have chelicerae, fangs that face towards each other, increasing the orientations that they can employ during prey-capture. They have fewer book lungs (when present) – usually one pair – and the females typically live one year. The Mygalomorphae have chelicerae, fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have two pairs of book lungs, and the females often live many years. Image:Cheiracanthium pun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolomedes
''Dolomedes'' is a genus of large spiders of the family Dolomedidae. They are also known as fishing spiders, raft spiders, dock spiders or wharf spiders. Almost all ''Dolomedes'' species are semiaquatic, with the exception of the tree-dwelling ''Dolomedes albineus, D. albineus'' of the southeastern United States. Many species have a striking pale stripe down each side of the body. They hunt by waiting at the edge of a pool or stream, then when they detect the ripples from prey, they run across the surface to subdue it using their foremost legs, which are tipped with small claws; then injecting venom with their hollow chelicerae to kill and digest the prey. They mainly eat insects, but some larger species are able to catch small fish. They can also climb beneath the water, when they become encased in a silvery film of air. "''Dolomedes''" is derived from the Greek word which means wily, deceitful. There are over a hundred species of ''Dolomedes'' throughout the world; examples ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider Taxonomy (biology), taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the National Museum of Natural History (France), Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraphyly
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
