Bothriocyrtum
''Bothriocyrtum'' is a genus of mygalomorph spiders in the family Halonoproctidae, first described by Eugène Simon in 1891. They are native to Mexico, Taiwan, and the southern United States. It was separated from ''Cyrtocarenum'' in 1891 for several reasons, including an increased width of separation and a distinctly different arrangement of the eyes. it contains only three species: ''B. californicum'', ''B. fabrile'', and ''B. tractabile''.

Halonoproctidae
Halonoproctidae is a family of mygalomorph spiders, split off from the family Ctenizidae in 2018. Species in the family are widely distributed in North and Central America, Australasia, Asia, southern Europe and North Africa. One species is recorded from Venezuela in South America. They are relatively large, sombrely coloured spiders, that live in burrows with some kind of trapdoor. Description Spiders of the family Halonoproctidae are of a medium to large size for spiders. They construct burrows with some kind of trapdoor, either wafer-like or cork-like. They range in colour from light brown to black, usually without any strongly distinctive body markings. The carapace is usually without hairs and has only a few spines. The sternum is longer than it is wide, and has sigillae at least in the posterior part. The eyes are arranged in two or three rows. Females do not have scopulae on their legs, but do have unique curved, thorn-like spines on the sides of legs I and II. Males have ...

Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to them forming trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the " primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realized that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the branching ...

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 ...

Octavius Pickard-Cambridge
Octavius Pickard-Cambridge Fellow of the Royal Society, FRS (3 November 1828 – 9 March 1917) was an England, English clergyman and zoologist. He was a keen arachnologist who described and named more than 900 species of spider. Life and work Pickard-Cambridge was born in Bloxworth rectory, Dorset, the fifth son of Rev. George Pickard, rector and squire of Bloxworth: the family changed its name to Pickard-Cambridge in 1848 after receiving the property left behind by a relative, Charles Owen Cambridge, of Whitminster House in Gloucestershire. Octavius was tutored at home by the poet William Barnes, after failing to receive admission to Winchester College. He also learned to play the violin from Sidney Smith. He then studied law in London before theology at the Durham University, University of Durham. He was very active and made many friends in this period. He served as steward at steeplechases and presided over the college choral society. In 1857 he presented the Pickard-Camb ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

BugGuide
BugGuide (or BugGuide.net) is a website and online community of naturalists, both amateur and professional, who share observations of arthropods such as insects, spiders, and other related creatures. The website consists of informational guide pages and many thousands of photographs of arthropods from the United States and Canada which are used for identification and research. The non-commercial site is hosted by the Iowa State University Iowa State University of Science and Technology (Iowa State University, Iowa State, or ISU) is a public land-grant research university in Ames, Iowa. Founded in 1858 as the Iowa Agricultural College and Model Farm, Iowa State became one of the ... Department of Entomology.
