The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3,000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to their creation of trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs.
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 Atracidae.
Ctenizidae is a small family of mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation, and silk. They may be called trapdoor spiders, as are other, similar species, such as those of the families Liphistiidae, Barychelidae, and Cyrtaucheniidae, and some species in the Idiopidae and Nemesiidae. The name comes from the distinctive behavior of the spiders to construct trapdoors, and ambush prey from beneath them.
The family Cyrtaucheniidae, known as wafer-lid trapdoor spiders, are a widespread family of Mygalomorphae spiders.
Idiopidae, also known as armored or spiny trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889.
Microstigmatidae is a small family of spiders with about 38 described species in eleven genera. They are small ground-dwelling and free-living spiders that make little use of silk.
Nemesiidae is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae". The family is sometimes referred to as wishbone spiders due to the shape of their burrows.
Cethegus is a genus of mygalomorph spiders in the curtain-web family Euagridae. It s endemic to Australia and was first described by Tamerlan Thorell in 1881.
Homostola is a genus of African mygalomorph spiders in the family Bemmeridae. It was first described by Eugène Louis Simon in 1892. Originally placed with the Ctenizidae, it was transferred to the wafer trapdoor spiders in 1985, and to the Bemmeridae in 2020. It is a senior synonym of Stictogaster and Paromostola.
Leptothele is a genus of Southeast Asian spiders in the family Euagridae first described by Robert Raven and Peter J. Schwendinger in 1995. It is native to the Malay Peninsula.
Namirea is a genus of mygalomorph spiders in the family Euagridae. It is endemic to Australia, and was first described by Robert Raven in 1984.
Phyxioschema is a genus of Asian spiders in the family Euagridae. It was first described by Eugène Simon in 1889.
Entypesa is a genus of African mygalomorph spiders in the family Entypesidae. It was first described by Eugène Louis Simon in 1902. Originally placed with the curtain-web spiders, it was transferred to the funnel-web trapdoor spiders in 1985, then to the Entypesidae in 2020. It is a senior synonym of Pseudohermacha.
Leptothele bencha is a species of spiders in the family Euagridae first described by Robert Raven & Peter J. Schwendinger in 1995, and is native to the Malay Peninsula.
Anamidae is a family of Australian mygalomorph spiders. It was first described as a tribe by Simon in 1889, then raised to the subfamily Anaminae of the family Nemesiidae, before being raised to a family level by Opatova et al. in 2020.
Bemmeridae is a family of African and Asian mygalomorph spiders that was first described as the tribe Bemmereae by Eugène Simon in 1903. It was elevated to a subfamily of funnel-web trapdoor spiders (Bemmerinae) in 1985, then to its own family in 2020.
Pycnothelidae is a family of mygalomorph spiders first described in 1917. It was downgraded to a subfamily of the funnel-web trapdoor spiders in 1985, but returned to family status in 2020.
Malayathele is a genus of southeast Asian mygalomorph spiders in the family Euagridae. It was first described by Peter J. Schwendinger, C. Lehmann-Graber and K. Hongpadharakiree in 2020, and it has only been found in Malaysia.
Rhytidicolidae, also known as golden tunnel-web spiders, is a small Neotropical family of mygalomorph spiders first described by Eugène Simon in 1903. It was originally described as a tribe and considered a junior synonym of Aporoptychinae Simon, 1889 by Raven in 1985.
