Calisoga is a genus of spiders in the family Nemesiidae, first described in 1937 by Ralph Vary Chamberlin. [3] As of February 2019 [update] , it contains five species, all in the USA. [1]
Cybaeidae is a family of spiders first described by Nathan Banks in 1892. The diving bell spider or water spider Argyroneta aquatica was previously included in this family, but is now in the family Dictynidae.
Nemesiidae is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae". The family is sometimes referred to as wishbone spiders due to the shape of their burrows.
Acanthogonatus is a genus of South American mygalomorph spiders in the family Pycnothelidae. It was first described by Ferdinand Anton Franz Karsch in 1880. Originally placed with the brushed trapdoor spiders, it was transferred to the funnel-web trapdoor spiders in 1985, then to the Pycnothelidae in 2020.
Rhianodes is a monotypic genus of Southeast Asian brushed trapdoor spiders containing the single species, Rhianodes atratus. It was first described by Robert Raven in 1985, and was later renamed to "Rhianodes" because the name was already attributed to a genus of weevils in the subfamily Apostasimerini. These spiders have only been found in Malaysia, Singapore, and Philippines.
Cybaeota is a genus of North American araneomorph spiders in the family Cybaeidae, and was first described by R. V. Chamberlin & Wilton Ivie in 1933. It was moved to the Cybaeidae in 1967.
Blabomma is a genus of araneomorph spiders in the family Cybaeidae, and was first described by R. V. Chamberlin & Wilton Ivie in 1937. Originally placed with the funnel weavers, it was moved to the Dictynidae in 1967, and to the Cybaeidae in 2017.
Tivyna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by R. V. Chamberlin in 1948.
Yorima is a genus of araneomorph spiders in the family Cybaeidae and was first described by R. V. Chamberlin & Wilton Ivie in 1942. Originally placed in the funnel weaver family, it was moved to the Dictynidae in 1967, and to the Cybaeidae in 2017.
Clavopelma is a monotypic genus of Mexican tarantulas containing the single species, Clavopelma tamaulipeca. It is a reddish-brown spider with thick, wooly golden-brown hair. Its legs are a darker shade of brown than the carapace, with setae that are stiffer than the hair on its body. Both sets of eyes are more or less equal in length, though the forward set is sharply procurved.
Kwonkan is a genus of Australian mygalomorph spiders first described by Barbara York Main in 1983. It was originally assigned to Dipluridae, but was later assigned to Nemesiidae due to similarities to the genus Aname, before being transferred to the family Anamidae in 2010. The known distribution of described species in the genus is restricted to the states of South Australia (SA) and Western Australia (WA). Yilgarnia is now considered a synonym for this genus, and its type species is assigned to Kwonkan currycomboides.
Pionothele is a genus of African mygalomorph spiders in the family Pycnothelidae. It was first described by William Frederick Purcell in 1902. As of June 2020 it contains 2 species, found in Namibia and South Africa: P. gobabeb, and P. straminea. Originally placed with the Ctenizidae, it was transferred to the funnel-web trapdoor spiders in 1985, then to the Pycnothelidae in 2020.
Pycnothele is a genus of South American mygalomorph spiders in the family Pycnothelidae. First described by Ralph Vary Chamberlin in 1917, it was moved to the funnel-web trapdoor spiders in 1985, but moved back to Pycnothelidae in 2020. It is a senior synonym of Agersborgia and Androthelopsis.
Apodrassus is a monotypic genus of South American ground spiders containing the single species, Apodrassus andinus. It was first described by R. V. Chamberlin in 1916, and has only been found in Peru.
Eulaira is a genus of North American dwarf spiders that was first described by Ralph Vary Chamberlin & Vaine Wilton Ivie in 1933.
Oreonetides is a genus of dwarf spiders that was first described by Embrik Strand in 1901.
Tutaibo is a genus of sheet weavers that was first described by Ralph Vary Chamberlin in 1916.
Phruronellus is a genus of North American araneomorph spiders first described by R. V. Chamberlin in 1921. Originally placed with the Liocranidae, it was moved to the Corinnidae in 2002, and to the Phrurolithidae in 2014.
Phrurotimpus is a genus of araneomorph spiders first described by R. V. Chamberlin and Wilton Ivie in 1935. The name is a compound adjective meaning "guarding the stone". Originally added to the Liocranidae, it was moved to the Corinnidae in 2002, then to the Phrurolithidae in 2014. They have red egg sacs that look like flattened discs, often found on the underside of stones.
Piabuna is a genus of North American araneomorph spiders first described by R. V. Chamberlin & Wilton Ivie in 1933. Originally added to the Liocranidae, it was moved to the Corinnidae in 2002, then to the Phrurolithidae in 2014.
Pycnothelidae is a family of mygalomorph spiders first described in 1917. It was downgraded to a subfamily of the funnel-web trapdoor spiders in 1985, but returned to family status in 2020.
