Several families within the infraorder Mygalomorphae contain trapdoor spiders: Actinopodidae, a family otherwise known as 'mouse-spiders', in South America and Australia
Ctenizidae (/ ˈ t ə n ɪ z ə d iː / tə-NIZZ-ə-dee) [2] 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 Nemesiid
Most spiders in this family build trapdoor burrows. For example, the 20 millimetres (0.79 in) long Sipalolasma builds its burrow in rotted wood, with a hinged trapdoor at each end. The 10 millimetres (0.39 in) long Idioctis builds its burrow approximately 5 centimetres (2.0 in) deep, just below the high tide level, sealing the opening with a ...
Spiders of the family Halonoproctidae are of a medium to large size for spiders. They construct burrows with some kind of trapdoor, either wafer-like or cork-like. They range in colour from light brown to black, usually without any strongly distinctive body markings. The carapace is usually without hairs and has only a few spines.
A number of spiders can cause spider bites that are medically important. Almost all spiders produce venom but only a few are able to cause significant harm to humans. [1] Two medically important spider genera have a worldwide distribution—Latrodectus and Loxosceles. Others have a limited distribution.
