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 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.

Description
The spiders have large bodies, similar to those of 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. The lateral posterior spinnerets are elongated.

The oldest known idiopid, Number 16, died at the age of 43 years.
