The family Dipluridae, known as curtain-web spiders are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that move up and down in a stabbing motion. A number of genera, including that of the Sydney funnel-web spider (Atrax), used to be classified in this family but have now been moved to Atracidae.
Philodromidae, also known as philodromid crab spiders and running crab spiders, is a family of araneomorph spiders first described by Tord Tamerlan Teodor Thorell in 1870. It contains over 500 species in thirty genera.
Grammostola is a genus of South American tarantulas that was first described in text by Eugène Louis Simon in 1892. These medium- to large-sized spiders are native to tropical South America, and are usually brown in color, with pinkish or orangish-red hairs. The very docile Chilean rose tarantula is popular as a beginner's spider among tarantula enthusiasts.
Beata is a genus of jumping spiders that was first described by George Peckham & Elizabeth Peckham in 1895.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 39 genera.
Hogna is a genus of wolf spiders with more than 200 described species. It is found on all continents except Antarctica.
Euathlus is a genus of South American tarantulas that was first described by Anton Ausserer in 1875. These spiders are medium sized and are usually found in high elevations in the Andes. It is a senior synonym of Paraphysa, and was formerly considered a senior synonym of Brachypelma, but this was later rejected.
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.
Cyclosternum is a genus of tarantulas that was first described by Anton Ausserer in 1871.
The Ischnocolinae are a problematic subfamily of tarantulas. In 1892, Eugène Simon based the group, which he noted was only weakly homogeneous, on the presence of divided tarsal scopulae. This feature was later considered to be plesiomorphic, and both morphological and molecular phylogenetic studies have shown that, as traditionally circumscribed, the subfamily is not monophyletic. A much more narrowly defined Ischnocolinae sensu stricto was proposed in 2014. One of the authors of that proposal subsequently said that no further taxonomic changes should be considered until there had been a more comprehensive sampling of the subfamily. As of January 2021, the status of the Ischnocolinae remains unresolved.
Sericopelma is a genus of tarantula, found in Central America from Nicaragua to Panama. The limits of the genus and its distribution have long been confused; it is closely related to the genus Aphonopelma. Sericopelma species are among the largest found in Central America. They can be kept as pets, although at least one species has been described as "very aggressive".
Ischnocolus is a genus of tarantulas that was first described by Anton Ausserer in 1871. This tarantula genus includes some of the smallest in the family.
Bolostromus is a genus of wafer trapdoor spiders that was first described by Anton Ausserer in 1875.
Cyrtopholis is a genus of tarantulas that was first described by Eugène Louis Simon in 1892.
Hapalopus is a genus of tarantulas that was first described by Anton Ausserer in 1875.
Schismatothele is a genus of South American tarantulas that was first described by Ferdinand Anton Franz Karsch in 1879.
Stichoplastoris is a genus of Central American tarantulas that was first described by J.-P. Rudloff in 1997.
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.
