Trapdoor spider
（重定向自Ctenizidae）
Trapdoor spiders, members of the family Ctenizidae, are medium-sized mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation and silk. Some similar species are also called trapdoor spiders, such as those of the families Liphistiidae, Barychelidae, Cyrtaucheniidae and some species in Idiopidae and Nemesiidae. Some Conothele species do not build a burrow, but construct a silken tube with trapdoor in bark crevices.
