The family Cyrtaucheniidae, known as wafer-lid trapdoor spiders, are a widespread family of Mygalomorphae spiders.
Brachypelma smithi is a species of spider in the family Theraphosidae (tarantulas) native to Mexico. It has been confused with Brachypelma hamorii; both have been called Mexican redknee tarantulas. Mexican redknee tarantulas are a popular choice as pets among tarantula keepers. Many earlier sources referring to B. smithi either relate to B. hamorii or do not distinguish between the two species. B. smithi is a terrestrial tarantula native to Pacific coast of the Mexican state of Guerrero.
Spider behavior refers to the range of behaviors and activities performed by spiders. Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms which is reflected in their large diversity of behavior.
Myrmekiaphila neilyoungi is a species of spider in the family Euctenizidae, described in 2007 by East Carolina University professor of biology Jason E. Bond and Norman I. Platnick, curator at the American Museum of Natural History in New York City. It is named after Canadian rock musician Neil Young.
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.
Jason E. Bond is an American biologist working as a Professor of Entomology and the Schlinger Chair in Insect Systematics at the University of California, Davis.
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 barackobamai is a large species of trapdoor spider in the family Euctenizidae named after the 44th President of the United States, Barack Obama. The species was first reported by Jason Bond of Auburn University in December 2012 as one of 33 new species of the genus Aptostichus. The species is endemic throughout northern California, forming burrows out of silk, dirt, and sand, from which it attacks prey. This spider is identified by its dark red to red-brown coloration with a stripped or chevron patterned abdomen. Breeding occurs during the winter and females tend to be larger than their male counterparts. A. barackobamai is part of the larger Aptostichus icenoglei species complex, and is a close relative to Aptostichus icenoglei and Aptostichus isabella.
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.
Cantuaria dendyi is a species of trapdoor spider in the family Idiopidae. It can be found in the South Island of New Zealand and is limited to the Christchurch and Banks Peninsula area.
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.
Tliltocatl is a genus of North American tarantulas that was split off from Brachypelma in 2020. They are also large burrowing tarantulas, but don't have the striking red leg markings of Brachypelma species. A female T. vagans can grow up to 50 mm (2.0 in) long and legs can get as long as 55 mm (2.2 in). They are found predominantly in Mexico, with some species native to Central America. The name is derived from two Nahuatl words, "tlil", meaning "black", and "tocatl", meaning "spider". Habitat destruction and collection for the pet trade has led to this and Brachypelma to be protected under International Convention on International Trade of Endangered Species rules, beginning with B. smithi.
Euoplos dignitas is a species of armored golden trapdoor spider in the family Idiopidae. It is found in Queensland, Australia.
Fagilde's trapdoor spider or buraqueira-de-Fagilde in Portuguese, is a trapdoor spider of the family Nemesiidae, currently only known from Fagilde and the adjacent village of Vila Garcia, both in the Mangualde municipality of the Beira Alta region of Portugal, in the isolated slopes of the River Dão valley.
