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 tarantulas are popular as a beginner's spider among tarantula enthusiasts.
Diplura is a genus of South American curtain web spiders that was first described by C. L. Koch in 1850. It is found in South America and Cuba belonging to the subfamily Diplurinae. They possess a lyra on their prolateral maxillae. Diplura species can be distinguished from Trechona sp. by the number of setae on this lyra. They differ from Harmonicon sp. by the leg formula and the shape of the lyra bristles.
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 August 2022, 1,040 species have been identified, with 156 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.
Cyriocosmus is a genus of tarantulas that was first described by Eugène Louis Simon in 1903. They are small to medium spiders, with a bicolored or one same color carapace.
Cyclosternum is a genus of tarantulas that was first described by Anton Ausserer in 1871.
Tmesiphantes uru is a species of tarantula in the subfamily Theraphosinae. It is endemic to Argentina.
Tmesiphantes mutquina is a species of theraphosid spider in the subfamily Theraphosinae. It is native to Argentina.
Tmesiphantes yupanqui is a species of spider in the subfamily Theraphosinae of the family Theraphosidae. It is endemic to Argentina.
Tmesiphantes crassifemur is a species of theraphosine theraphosid spider. It is native to Argentina.
Acanthogonatus is a genus of South American mygalomorph spiders in the family Pycnothelidae. It was first described by Ferdinand Anton Franz Karsch in 1880. Originally placed with the brushed trapdoor spiders, it was transferred to the funnel-web trapdoor spiders in 1985, then to the Pycnothelidae in 2020.
Cyrtopholis is a genus of tarantulas that was first described by Eugène Louis Simon in 1892.
Homoeomma is a genus of South American tarantulas that was first described by Anton Ausserer in 1871. It is considered a senior synonym of Calopelma, Butantania, and of Cyclothoracoides. These tarantulas are usually quite small and usually burrow a few centimeters under a rock or log.
Plesiopelma is a genus of South American tarantulas that was first described by Reginald Innes Pocock in 1901. Plesiopelma species are particularly abundant along mountainous ranges, frequently living under stones. Both males and females live in silk tubes under stones with aggregate spatial distribution. The walls of these tunnels are covered by waterproof silk, protecting them from floods. In addition, there is a uniform saturated microclimate inside the tunnel, which protects the spiders from dehydration.
Schismatothele is a genus of South American tarantulas that was first described by Ferdinand Anton Franz Karsch in 1879.
Pycnothele is a genus of South American mygalomorph spiders in the family Pycnothelidae. First described by Ralph Vary Chamberlin in 1917, it was moved to the funnel-web trapdoor spiders in 1985, but moved back to Pycnothelidae in 2020. It is a senior synonym of Agersborgia and Androthelopsis.
Homoeomma elegans is a species of spiders in the family Theraphosidae. It is found in Argentina.
Guyruita cerrado is a species of spider in the genus Guyruita. The species has originally been described by José P.L. Guadanucci, Sylvia M. Lucas, Rafael P. Indicatti and Flávio U. Yamamoto.
