The family Cyrtaucheniidae, known as wafer-lid trapdoor spiders, are a widespread family of Mygalomorphae spiders.
Myrmekiaphila is a genus of North American mygalomorph trapdoor spiders in the family Euctenizidae, and was first described by G. F. Atkinson in 1886. All described species are endemic to the southeastern United States.
Aptostichus stephencolberti is a species of spider in the family Euctenizidae, named after the American satirist Stephen Colbert. The spider was discovered on the California coastline in 2007.
Aptostichus is a genus of North American mygalomorph spiders in the family Euctenizidae, and was first described by Eugène Simon in 1891. They are found predominantly in southern California, United States.
Aptostichus angelinajolieae, the Angelina Jolie trapdoor spider, is a species of Euctenizidae, nocturnal arthropods who seize their prey after leaping out of their burrows and inject it with venom. It was described by the Auburn University professor Jason Bond in 2008, who named it after the American actress Angelina Jolie in recognition of her work on the United Nations High Commission for Refugees. It was one of only seven described species of Aptostichus until 2012, when it was joined by Bono's Joshua Tree trapdoor spider and 32 other species.
Aptostichus miwok is a species of spiders in the family Euctenizidae named after the Coast Miwok Indian tribe known to have inhabited the coastal areas of California from the Golden Gate northward prior to European settlement. It is similar to the Aptostichus angelinajolieae named after actress Angelina Jolie and Aptostichus stephencolberti named after satirist Stephen Colbert described by the same author.
Aptostichus bonoi, or Bono's Joshua Tree trapdoor spider, is a morphological species of Euctenizidae spiders, nocturnal arthropods who seize their prey after leaping out of their burrows and inject it with venom. The species was found in Joshua Tree National Park, California, and described by the Auburn University professor Jason Bond in 2012. Only seven species of Aptostichus were known prior to 2012, including the Angelina Jolie trapdoor spider.
Aptostichus barackobamai, the Barack Obama trapdoor spider, is a species of spider in the family Euctenizidae named after the 44th President of the United States, Barack Obama. The species was first reported by Professor Jason Bond of Auburn University in December 2012 as one of 33 new species of the genus Aptostichus.
Apomastus schlingeri is a species of venomous spiders belonging to a family of trapdoor spiders. They produce a complex of neurotoxins called aptotoxins. Both known species of the genus are found in the United States.
The Euctenizidae are a family of mygalomorph spiders. They are now considered to be more closely related to Idiopidae.
Eucteniza is a genus of trapdoor spiders in the family Euctenizidae containing at least 14 species occurring in Mexico and the southern United States. Species are distinguished by a softened rear portion of the carapace, and males possess large spines on the first two pairs of walking legs that are used to hold females during mating. Like other trapdoor spiders they create burrows with a hinged lid, from which they await passing insects and other arthropods to prey upon. Many species are known from only one or two localities, or from only male specimens. More species are expected to be discovered. Eucteniza is closely related to spiders of the genera Entychides and Neoapachella.
Entychides is a genus of mygalomorph trapdoor spiders in the family Euctenizidae, and was first described by Eugène Simon in 1888. Originally placed with the Ctenizidae, it was moved to the wafer trapdoor spiders in 1985, then to the Euctenizidae in 2012.
Aptostichus simus is a species of trapdoor spider in the family Euctenizidae. It is a medium-sized mygalomorph found in the United States and Mexico.
Apomastus is a genus of North American mygalomorph spiders in the family Euctenizidae, and was first described by Jason Bond & B. D. Opell in 2002. As of May 2019 it contains only two species, both found in the Los Angeles Basin of southern California: A. kristenae and A. schlingeri.
Myrmekiaphila comstocki is a spider in the family Euctenizidae, in the infraorder Mygalomorphae ("mygalomorphs"). The distribution range of Myrmekiaphila comstocki includes the USA and Mexico.
Eucteniza relata, the southwestern trapdoor spider, is a species of wafer-lid trapdoor spider in the family Euctenizidae. It is found in the United States and Mexico.
Apomastus kristenae is a species of wafer-lid trapdoor spider in the family Euctenizidae. It is found in the United States.
Promyrmekiaphila winnemem is a species of wafer-lid trapdoor spider in the family Euctenizidae. It is found in the United States.
Aptostichus atomarius, the San Bernardino hills trapdoor spider, is a species of wafer-lid trapdoor spider in the family Euctenizidae. It is found in the United States.
