Synonyms [1]

Euathlus is a genus of South American tarantulas that was first described by Anton Ausserer in 1875. [3] These spiders are medium sized and are usually found in high elevations in the Andes. [4] It is a senior synonym of Paraphysa, [2] and was formerly considered a senior synonym of Brachypelma , [5] but this was later rejected. [6]

Diagnosis

Males own a palpal bulb with two prolateral keels, with the tip curved retrolaterally. The tibial apophyses has retrolateral spines and a spine on the retrolateral branch which almost reached the apex. And a urticating patch in the center of the opisthosoma, which own mainly type 3 and 4 urticating hairs. Females also can be distinguished by two 4 sided spermathecal receptacles, with sphere like chambers. [4]

Species

As of July 2022 it contains fourteen species, found in Argentina, Chile and Peru: [1]

<i>Avicularia</i> Genus of spiders

Avicularia is a genus of the family Theraphosidae containing various species of arboreal tarantulas. The genus is native to Panama, the Caribbean, and tropical South America. Each species in the genus has very distinguishable pink foot pads.

<i>Brachypelma</i> Genus of spiders

Brachypelma is a genus of spiders in the family Theraphosidae (tarantulas). They may have bodies up to 6 cm long with legs of similar or greater lengths. Some species have brightly colored legs, with red or orange marks and rings.

<i>Grammostola</i> Genus of spiders

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.

<i>Tliltocatl vagans</i> Species of spider

Tliltocatl vagans is a species of tarantula known commonly as the Mexican red rump. It ranges predominantly in Mexico, but is also found in Central America. They are terrestrial, burrowing spiders. The reason for the name red rump is because of its distinctive red hairs on its abdomen. Like most tarantulas, they will eat anything they can overpower, which is usually insects, but small lizards and rodents may also be consumed. They can grow up to a solid 6.5 inch leg span, with males typically being smaller and thinner than the females. They prefer shrubland habitats.

<i>Tliltocatl albopilosus</i> Species of spider

Tliltocatl albopilosus is a species of tarantula, also known as the curlyhair tarantula. The species' native range is Costa Rica. They are largely terrestrial, opportunistically burrowing spiders.

<i>Brachypelma boehmei</i> Species of spider

Brachypelma boehmei is a tarantula native to Mexico in Guerrero state. These long-lived tarantulas prefer burrowing and hiding in dry scrubland. As with all closely related tarantula species, they defend themselves with urticating hair when provoked.

Cyclosternum is a genus of tarantulas that was first described by Anton Ausserer in 1871.

<i>Bumba</i> (spider) Genus of spiders

Bumba is a genus of tarantula native to the Americas. It is an uncommon genus, comprising eight known species, including one named after John Lennon. Like most related species in the subfamily Theraphosinae, they may flick urticating hairs in response to threats.

<i>Sericopelma</i> Genus of spiders

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".

Tmesiphantes uru is a species of tarantula in the subfamily Theraphosinae. It is endemic to Argentina.

Hapalopus is a genus of tarantulas that was first described by Anton Ausserer in 1875.

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.

<i>Homoeomma</i> Genus of spiders

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.

<i>Tliltocatl</i> Genus of tarantulas

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.

Phrixotrichus scrofa is a tarantula spider, commonly known as the Chilean copper, Chilean pink burst or Chilean violet tarantula. It was first described by Juan Ignacio Molina in 1782. Its synonyms include Phrixotrichus auratus, Paraphysa scrofa, and possibly Phrixotrichus chilensis. It is native to Chile and Argentina, inhabiting mainly arid forests, and is kept as a pet somewhat commonly.
