Idiopidae, also known as armored or spiny trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 39 genera.
Migidae, also known as tree trapdoor spiders, is a family of spiders with about 100 species in eleven genera. They are small to large spiders with little to no hair and build burrows with a trapdoor. Some species live in tree fern stems. They have a Gondwanan distribution, found almost exclusively on the Southern Hemisphere, occurring in South America, Africa, Madagascar, Australia, New Zealand and New Caledonia.
The Harpactirinae are a subfamily of tarantulas which are native to the continent of Africa. Like many Old World tarantulas, they have a relatively strong venom and can inflict a painful bite.
Pamphobeteus is a genus of tarantulas that was first described by Reginald Innes Pocock in 1901. It includes some of the largest spiders in the world. They are found in South America, including the countries of Peru, Bolivia, Ecuador, Brazil, Colombia and Panama.
Psalmopoeus is a genus of the family Theraphosidae containing various species of tarantulas. The genus is native to Trinidad and Tobago, Colombia, Ecuador, Venezuela, Guyana, Brazil, Belize, Panama, Nicaragua, Costa Rica, Mexico, Guatemala and Honduras. All of these tarantulas are arboreal in nature, Psalmopoeus victori being the first arboreal tarantula of Mexico.
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of December 2023, 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.
Brachypelma albiceps is a species of spider in the tarantula family, Theraphosidae. It is known as the Mexican golden red rump tarantula or the Amula red rump tarantula. The carapace is a light golden color and the abdomen dark, covered with long red hairs. Females typically live for about 15 years. Males usually live about 5 years or up to 12 months after the last molt.
Idiops is a genus of armored trapdoor spiders that was first described by Josef Anton Maximilian Perty in 1833. It is the type genus of the spurred trapdoor spiders, Idiopidae. Idiops is also the most species-rich genus of the family, and is found at widely separated locations in the Neotropics, Afrotropics, Indomalaya and the Middle East. Females live in tubular burrows lined with a thick layer of white silk. These typically have a D-shaped lid that fits into the entrance like a cork, and some burrows have two entrances. The lid may consist of mud, moss or lichen, which is bound below by a thick layer of silk. As in all genera of this family, the anterior lateral eyes (ALE) are situated near the clypeal margin, far in front of the remaining six eyes, which are arranged in a tight group. The males which are smaller in size, wander about or occasionally live in burrows. Like other mygalomorphs, they are relatively large and long-lived. Forest clearance and agricultural practices that loosen the soil and enhance erosion, besides soil removal for brick making have been pointed out as serious threats to some Indian species. Species ranges are poorly known – in India for instance, most species are known only from their type localities.
Heligmomerus is a genus of armored trapdoor spiders that was first described by Eugène Louis Simon in 1892.
Scelidomachus socotranus is a species of spider found on the island of Socotra in the Indian Ocean. It is the only member of its genus.
Batesiella is a monotypic genus of African tarantulas containing the single species, Batesiella crinita. It was first described by Reginald Innes Pocock in 1903, and is found in Cameroon. It is named in honor of the collector, G. L. Bates. It was synonymized with Encyocrates from 1985 to 1990.
Harpactira is a genus of African tarantulas that was first described by Anton Ausserer in 1871.
Stasimopus is a genus of African mygalomorph spiders that was first described by Eugène Louis Simon in 1892. It is the only genus in the family Stasimopidae.
Atrophothele is a monotypic genus of Asian brushed trapdoor spiders containing the single species, Atrophothele socotrana. It was first described by Reginald Innes Pocock in 1903, and has only been found in Yemen.
Brachionopus is a genus of South African tarantulas that was first described by Reginald Innes Pocock in 1897. It was transferred to the Theraphosidae from the Barychelidae in 1985.
Spiroctenus is a genus of African mygalomorph spiders in the family Bemmeridae. It was first described by Eugène Louis Simon in 1889. Originally placed with the Ctenizidae, it was transferred to the funnel-web trapdoor spiders in 1985, and to the Bemmeridae in 2020. It is a senior synonym of Bemmeris, Bessia, and Ctenonemus.
Bassaniodes is a genus of crab spiders that was first described by Reginald Innes Pocock in 1903.
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.
