Strophaeus is a genus of brushed trapdoor spiders first described by Anton Ausserer in 1875. [2]
As of April 2019 [update] it contains four species: [1]
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 Hexathelidae.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera.
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.
Idiops is a genus of armored trapdoor spiders that was first described by Josef Anton Maximilian Perty in 1833. It is the type genus of the spurred trapdoor spiders, Idiopidae. Idiops is also the most species-rich genus of the family, and is found at widely separated locations in the Neotropics, Afrotropics, Indomalaya and the Middle East. Females live in tubular burrows lined with a thick layer of white silk. These typically have a D-shaped lid that fits into the entrance like a cork, and some burrows have two entrances. The lid may consist of mud, moss or lichen, which is bound below by a thick layer of silk. As in all genera of this family, the anterior lateral eyes (ALE) are situated near the clypeal margin, far in front of the remaining six eyes, which are arranged in a tight group. The males which are smaller in size, wander about or occasionally live in burrows. Like other mygalomorphs, they are relatively large and long-lived. Forest clearance and agricultural practices that loosen the soil and enhance erosion, besides soil removal for brick making have been pointed out as serious threats to some Indian species. Species ranges are poorly known – in India for instance, most species are known only from their type localities.
Cyclosternum is a genus of tarantulas that was first described by Anton Ausserer in 1871.
Eucteniza is a genus of trapdoor spiders in the family Euctenizidae containing at least 14 species occurring in Mexico and the southern United States. Species are distinguished by a softened rear portion of the carapace, and males possess large spines on the first two pairs of walking legs that are used to hold females during mating. Like other trapdoor spiders they create burrows with a hinged lid, from which they await passing insects and other arthropods to prey upon. Many species are known from only one or two localities, or from only male specimens. More species are expected to be discovered. Eucteniza is closely related to spiders of the genera Entychides and Neoapachella.
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".
Euagrus is a genus of spider in the family Euagridae. It was first described by Anton Ausserer in 1875. It has been referred to as "Evagrus", but this is a transcript error, not an accepted synonym. It is very similar to the genus Allothele, and several species have been transferred there, including Euagrus caffer, Euagrus regnardi, and Euagrus teretis.
Idiommata is a genus of brushed trapdoor spiders first described by Anton Ausserer in 1871. It is endemic to Australia.
Bolostromus is a genus of wafer trapdoor spiders that was first described by Anton Ausserer in 1875.
Ischnothele, also known as scatter-web spiders is a genus of spiders in the family Ischnothelidae. It was first described by Anton Ausserer in 1875.
Hapalopus is a genus of tarantulas that was first described by Anton Ausserer in 1875.
Megaphobema is a genus of tarantulas that was first described by Reginald Innes Pocock in 1901. They look similar to members of Pamphobeteus except for its legs; the third and fourth pairs of legs are much larger and stronger than the first two pairs.
Ischnothelidaeis a family of mygalomorph spiders. It was first described as a subfamily of the family Dipluridae by F.O. Pickard-Cambridge in 1897 and raised to a family by Opatova et al. in 2020. They are also known as scatter-web spiders.
