Hexurella is a genus of spiders, found in the United States and Mexico. [2] It is the only genus in the family Hexurellidae. [1]
As of April 2016 [update] , the World Spider Catalog accepted the following species: [2]
Liocranidae is a family of araneomorph spiders first described by Eugène Simon in 1897. They are one of several groups called "sac spiders". The holarctic genus Agroeca is the best-known, but it also includes various genera of more obscure spiders that still lack a diagnosis. Two species in the North American genus Neoanagraphis are found in the extremely dry conditions in the Mojave, Sonoran and Chihuahuan deserts. Females live in animal burrows while males wander and are the ones most often caught in pitfall traps.
Leptonetidae is a family of small spiders adapted to live in dark and moist places such as caves. The family is relatively primitive having diverged around the Middle Jurassic period. They were first described by Eugène Simon in 1890.
Dwarf tarantulas, also known as sheet funnel-web spiders are a type of spider from the family Mecicobothriidae. Dwarf tarantulas are one of several families of the suborder Mygalomorphae; this larger group also includes the true tarantulas.
Microstigmatidae is a small family of spiders with about 25 described species in eight genera. They are small ground-dwelling and free-living spiders that make little use of silk.
Anapidae is a family of rather small spiders with 232 described species in 58 genera. It includes the former family Micropholcommatidae as the subfamily Micropholcommatinae, and the former family Holarchaeidae. Most species are less than 2 millimetres (0.079 in) long.
Sphodros is a genus of North American purseweb spiders first described by Charles Athanase Walckenaer in 1835. It was considered a synonym of Atypus until 1980.
Coneweb spiders (Diguetidae) are six-eyed haplogyne spiders that live in tangled space webs, fashioning a cone-like central retreat where they hide and lay eggs. It is a small family, containing only two genera with fifteen species and is confined to the New World, preferring deserts. Members of the genus Diguetia usually build their webs in shrubs or between cactus pads. They have the same eye arrangement as the venomous recluse spiders, but none are known to be harmful to humans.
Hexurella apachea is a species of spider native to the United States. It was first described by Gertsch and Platnick in 1979. It is from the family Hexurellidae.
Hexurella pinea is a species of spider native to the United States. It was first described by Gertsch and Platnick in 1979. It is from the family Hexurellidae.
Hexurella rupicola is a species of spider native to the United States. It was first described by Gertsch and Platnick in 1979. It is from the family Hexurellidae.
Hexurella encina is a species of spiders native to Mexico. It was first described by Gertsch and Platnick in 1979. It is from the family Hexurellidae.
Anapisona is a genus of araneomorph spiders in the family Anapidae, first described by Willis J. Gertsch in 1941.
Orthonops is a genus of North American araneomorph spiders in the family Caponiidae, first described by R. V. Chamberlin in 1924.
Appaleptoneta is a genus of North American Leptonetids that was first described by Norman I. Platnick in 1986.
Calileptoneta is a genus of North American Leptonetids that was first described by Norman I. Platnick in 1986.
Heteroonops is a genus of spiders in the family Oonopidae. It was first described in 1916 by Dalmas. As of July 2021, it contains about 25 species.
Noonops is a genus of spiders in the family Oonopidae. It was first described in 2013 by Platnick & Berniker. As of 2017, it contains 23 species from the U.S., Mexico, and the Bahamas.
Emboonops is a genus of spiders in the family Oonopidae. It was first described in 2015 by Bolzern, Platnick & Berniker. As of 2017, it contains 10 species, all from Mexico.
Titanebo is a genus of North American running crab spiders that was first described by Carl Eduard Adolph Gerstaecker in 1933.
