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.[4]
The oldest known idiopid, Number 16, died at the age of 43 years.[5]
