One of the larger species of tarantula, the Chaco golden knee, formerly known as Grammostola aureostriata, can be expected to reach between 20 and 22 cm (8.5 in).
Brachypelma klaasi is a tarantula endemic to Mexico and it is the rarest of the genus Brachypelma.
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.
Tliltocatl albopilosus is a species of tarantula, also known as the curlyhair tarantula. The species' native range is Nicaragua and Costa Rica. They are largely terrestrial, opportunistically burrowing spiders.
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.
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.
Poecilotheria ornata, known as the fringed ornamental or ornate tiger spider, is a large arboreal tarantula, which is endemic to Sri Lanka. Their legspan sometimes reaches 10 inches (25 cm) in females, and is probably the second largest of the genus, behind Poecilotheria rufilata.
Neosclerocalyptus was an extinct genus of glyptodont that lived during the Pliocene, Pleistocene, and Holocene of Southern South America, mostly Argentina. It was small compared to many glyptodonts at only around 2 meters long and 360 kilograms.
Hapalotremus martinorum is a species of tarantula in the subfamily Theraphosinae native to the High Yungas of Salta province, Argentina. It was first described in a 2015 publication by Patricio E. Cavallo and Nelson Ferretti.
Pachistopelma rufonigrum is a species of theraphosid, contained within the Aviculariinae subfamily. It is endemic to Brazil.
Eupalaestrus is a genus of South American tarantulas that was first described by Reginald Innes Pocock in 1901.
Cardiopelma is a genus of spiders in the family Theraphosidae. It was first described in 1999 by Vol. As of 2017, it contains only one species, Cardiopelma mascatum, known only from Mexico, in the state of Oaxaca.
Hemirrhagus is a genus of Mexican tarantulas that was first described by Eugène Louis Simon in 1903. It is considered a senior synonym of Spelopelma. Species of the genus Hemirrhagus are 5 to 12 cm long, usually black in colour, the urticating hairs on the opisthosoma are arranged in one dorsomedian patch, two dorsal paramedian patches, or two lateral patches. It is unique amongst the theraphosine genera because of the retrolateral coxal heels, the shape of the male palpal bulb, and the urticating hairs on the abdomen are reduced or completely missing. It is the only genus with epigean, troglophile and troglobitic species.
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.
Asemonea cuprea is a species of jumping spider in the genus Asemonea that is found in South Africa and Zambia. The spider was first defined in 2009 by Wanda Wesołowska, one of over 500 that the arachnologist described during her career. It is small, generally yellow and lives on the leaves of short shrubs. It has an pear-shaped carapace and a narrower abdomen that each have a length between 1.5 and 1.7 mm. The male has a distinctive coloration with bright orange scales covering the clypeus and eye field and vivid orange hairs on the back half of the abdomen, which are recalled by the species name. The male also has an unusual right-angle shaped subtegulum and the female a simpler epigyne than other Asemonea species that helps identify the species.
Avicularia juruensis is a species of spider in the family Theraphosidae, found in South America. Avicularia urticans was brought into synonymy in 2017. It has been given the English name Amazonian pink toe spider. Under the synonym Avicularia urticans, it is also known as the Peruvian pinktoe tarantula. It is a large mygalomorph spider, with a maximum body length over 30 mm (1.2 in) and the longest fully extended leg about 60 mm (2.4 in). Like other species in the genus Avicularia, specimens under this name are sold as pets, although their identity has not been confirmed by taxonomic studies.
Asemonea pinangensis is a species of jumping spider in the genus Asemonea that is endemic to Malaysia. The spider was first defined in 1980 by Fred Wanless. It is a small spider, with a carapace that is typically 1.16 mm (0.046 in) long and an abdomen typically 1.2 mm (0.047 in) long. The carapace is whitish-yellow with black markings and the abdomen black with whitish-yellow markings. The coloration, as well as the lip on its dorsal tibial apophysis, help distinguish the species from the otherwise similar Asemonea maculata, Asemonea minuta and Asemonea tanikawai. The female has not been described.
Hapalotremus chespiritoi is a tarantula in the Hapalotremus genus, first described by Nelson Ferretti, Patricio E. Cavallo, Juan C. Chaparro, Duniesky Ríos Tamayo, Tracie A. Seimon and Rick C. West in 2018. It is found in Peru, Patambuco, very close to Sicuani. This tarantula is named after Roberto Gómez Bolaños. The shape of the spermatheca of female of Hapalotremus chespiritoi resembles the small antennae of el "Chapulín Colorado", a comical superhero created by R.G. Bolaños.
Cyriocosmus leetzi also known as the Columbian dwarf tiger or Venezuelan dwarf beauty tarantula is a tarantula which was first described by Fabian Vol in 1999. As its common names may suggest it is found in Colombia, with some people stating it is also found in Venezuela.
Grammostola iheringi also known as the Entre Rios tarantula, it was first described by Keyserling in 1891. They are found in Brazil, and is considered the biggest tarantula in the Grammostola genus.
