Idiopidae
Idiopidae, also known as armored trapdoor spiders,[1] is a family of mygalomorph[2] spiders first described by Eugène Simon in 1889.[3] They have a large body similar to tarantulas.
In most species the males have a spur on their legs, which is used to immobilise the female and prevent her from biting during the mating process. Idiopidae build burrows, and some species close these with a door.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. Its lateral posterior spinnerets are elongated.[4]
