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 ...

Homoeomma
''Homoeomma'' is a genus of South American tarantulas that was first described by Anton Ausserer in 1871. It is considered a senior synonym of ''Calopelma'', ''Butantania'', and of ''Cyclothoracoides''. These tarantulas are usually quite small and usually burrow a few centimeters under a rock or log. Diagnosis Males of this genus can be distinguished by the tile-like apophysis on the base of the palpal bulb, and the embolus being in an obtuse angle, in relation to the bulb. Males also have a flexion of the metatarsus 1, which is between the branches of the tibial apophysis. Females can be distinguished by the spermatheca morphology, which lacks constriction in the apex. Species it contains thirteen species, found in South America: *'' Homoeomma brasilianum'' (Chamberlin, 1917) – Brazil *''Homoeomma chilense'' Montenegro & Aguilera, 2018 – Chile *'' Homoeomma elegans'' (Gerschman & Schiapelli, 1958) – Argentina *'' Homoeomma familiare'' Bertkau, 1880 – Brazil *'' Homo ...

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.
