Clynotis Severus
''Clynotis'' is a genus of spiders in the family Salticidae, or jumping spiders, contained within the subfamily Marpissinae. They are found across Australia and New Zealand, with some species occupying the Auckland Islands and one found exclusively on Snares Island. There are eight species currently described within the genus, the earliest noted being the type species ''Clynotis severus'', first described in Queensland, New South Wales, Australia in 1879 by Ludwig Carl Christian Koch. The most recent was described in 1931 by Lucien Berland. Two other species previously held within the genus were subsequently reclassified into the genus '' Tara''. As with most salticidae spiders, members of this genus are known for their ability to jump with agility, and for their strong vision. They are identifiable from the distinct shape of the cephalothorax and their eye patterns. Of their eight eyes, the front row of four feature a dramatically prominent anterior median pair, while the rear r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 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 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 fossil spider species '' Cenotextricella simoni'' was named in his ...

Salticidae Genera
Jumping spiders are a group of spiders that constitute the family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider families because of the shape of the cephalothorax and their eye pa ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Henry Roughton Hogg
Henry Roughton Hogg (9 February 1846 – 30 November 1923) was a British amateur arachnologist. Biography Born in Stockwell, Surrey, he attended Uppingham School from 1859-1862, and later studied at Christ's College, Cambridge, where he obtained his BA in 1868 and his MA in 1873. He settled in Australia in 1873 and took up business in Melbourne, founding the firm of Hogg, Robinson & Co. He married in 1881, and in 1900 returned to England and settled in the London district of Kensington. He became chairman of Sunderland District Electric Tramways ltd and a director of Sanderson, Murray & Elder Ltd. Hogg was a specialist of the spiders of Australia and New Zealand. He was a fellow and honorary treasurer of the Royal Society of Victoria, as well as a fellow of both the Zoological and Botanical Societies of London. He bequeathed his collections to the Natural History Museum of London. The genus ''Hoggicosa'' is named for the author. He died on the 30th November, 1923 and was bur ...

Spider Silk
Spider silk is a protein fibre spun by spiders. Spiders use their silk to make Spider web, webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to Ballooning (spider), float through the air, or to glide away from predators. Most spiders vary the thickness and stickiness of their silk for different uses. In some cases, spiders may even use silk as a source of food. While methods have been developed to collect silk from a spider by force, it is difficult to gather silk from many spiders compared to silk-spinning organisms such as Sericulture, silkworms. All spiders produce silk, and even in non-web building spiders, silk is intimately tied to courtship and mating. Silk produced by females provides a transmission channel for male vibratory courtship signals, while webs and draglines provide a substrate for female sex pheromones. O ...

Cephalothorax
The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind. (The terms ''prosoma'' and ''opisthosoma'' are equivalent to ''cephalothorax'' and ''abdomen'' in some groups.) The word ''cephalothorax'' is derived from the Greek words for head (, ') and thorax (, '). This fusion of the head and thorax is seen in chelicerates and crustaceans; in other groups, such as the Hexapoda (including insects), the head remains free of the thorax. In horseshoe crabs and many crustaceans, a hard shell called the carapace covers the cephalothorax. Arachnid anatomy Fovea The fovea is the centre of the cephalothorax and is located behind the head (only in spiders).Dalton, Steve (2008). ''Spiders; The Ultimate Predators''. A & C Black, London.
