Theridiosomatidae
The ray spiders (Theridiosomatidae) are a family of spiders first described by Eugène Simon in 1881. They are most recognizable for their construction of cone-shaped webs. The family contains several genera which actively hunt for prey by using their webs to slingshot themselves towards prey. Genera , the World Spider Catalog accepts the following genera: *'' Andasta'' Simon, 1895 – Seychelles, Malaysia, Sri Lanka *'' Baalzebub'' Coddington, 1986 – Central America, Brazil, Australia, China *'' Chthonopes'' Wunderlich, 2011 – Laos *'' Chthonos'' Coddington, 1986 – Ecuador, Brazil, Peru *'' Coddingtonia'' Miller, Griswold & Yin, 2009 – Malaysia, Laos *'' Cuacuba'' Prete, Cizauskas & Brescovit, 2018 *'' Epeirotypus'' O.

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 ...

Spiders Of Africa
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Araneomorphae Genera
The Araneomorphae (also called the Labidognatha) 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 of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have 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 four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This ''Atrax robustus'' shows the orientation of Myglamorphae fangs. Image:Che ...

Silhouette Island
Silhouette Island lies northwest of Mahé in the Seychelles. It is the third largest granitic island in the Seychelles. It has an area of 20.1 km2 and has a population of 200, mostly workers on the island. The main settlement is La Passe, where ''Hilton Hotel'' is located. The name Silhouette was given after Étienne de Silhouette (1709-1767), the French minister of finances under Louis XV. Geography The island is mountainous with five peaks over in elevation; Mont Dauban , Mont-Pot-a-Eau , Gratte Fesse , Mont Corgat and Mont Cocos Marrons . As such, it has some of the most dramatic scenery of the islands. Though superficially similar to neighbouring islands, much of Silhouette is made up of younger syenite dated from 63 million years ago. Between Point Ramasse Tout and Point Zeng Zeng lies the only surface volcanic ash in Seychelles. Demographics The population of 200 lives in 3 villages, Grand Barbe (no longer inhabited), which is on the west coast, Anse Mondon (no ...

Michael Saaristo
Michael I. Saaristo (1938 – 27 April 2008) was a Finnish arachnologist, with a particular interest in the spiders of the Seychelles. The World Spider Catalog lists 61 genus names or synonyms and 109 species names or synonyms of which he is the sole or co-author. His account of the spiders of the Seychelles was published in 2010, after his death, with the assistance of Yuri M. Marusik. The spider genera '' Saaristoa'' and '' Saaristattus'' were named after him. The World Spider Catalog The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of ... lists 15 species with the specific name ''saaristoi'', honouring him.

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.
