Idiopidae

Idiopidae, also known as armored or spiny trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889.

==Behaviour== Idiopidae build burrows, and some species close these with a trapdoor lined with silk. Prothemenops siamensis from Thailand, which is about 2 cm long, builds its retreat in a streamside vertical earth bank in lower montane rainforest. Each burrow has two or three entrances that lead into a main tube. The trapdoor is a form of safety and ways of ambushing prey. Idiopidae adapt and live in many various environments as seen by the map on the far right, which leads to the various species to co-exist with other Idiopidae and other spiders outside of the family. Idiopidae do not deliver a bite that is dangerous to humans.
