Synonyms [1]

Homoeomma is a genus of South American tarantulas that was first described by Anton Ausserer in 1871. [5] It is considered a senior synonym of Calopelma, [3] Butantania, [2] and of Cyclothoracoides. [4] These tarantulas are usually quite small and usually burrow a few centimeters under a rock or log. [6]

Diagnosis

Males of this genus can be distinguished by the tile-like apophysis on the base of the palpal bulb, and the embolus being in an obtuse angle, in relation to the bulb. Males also have a flexion of the metatarsus 1, which is between the branches of the tibial apophysis. Females can be distinguished by the spermatheca morphology, which lacks constriction in the apex. [6]

Species

As of August 2022 it contains thirteen species, found in South America: [1]

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

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.

<span class="mw-page-title-main">Tarantula</span> Family of spiders

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.

<i>Plesiopelma</i> Genus of spiders

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.
