Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 39 genera.

Behaviour

Most spiders in this family build trapdoor burrows. For example, the {{convert|20|mm}} long Sipalolasma builds its burrow in rotted wood, with a hinged trapdoor at each end. The {{convert|10|mm}} long Idioctis builds its burrow approximately {{convert|5|cm}} deep, just below the high tide level, sealing the opening with a thin trapdoor.{{cite book |last1=Murphy |first1=Frances |last2=Murphy |first2=John |date=2000 |title=An Introduction to the Spiders of South East Asia |publisher=Malaysian Nature Society |location=Kuala Lumpur }}

Some species avoid flooding by plugging their burrows, while others can avoid drowning by trapping air bubbles within the hairs covering their bodies.{{Cite journal|last=Bristowe|first=W.S.|date=September 1930|title=XXXIV.— Notes on the biology of spiders .—II.
