The Brushed trapdoor spiders (family Barychelidae) are a spider family with about 300 species in 44 generaPlatnick 2008] . This family is the only family in superfamily Barycheloidea.

Most spiders in this family build trap-door burrows. There are some species that avoid flooding by plugging their nests. Others can avoid drowning by trapping air bubbles within the hairs covering their bodies. Members of this group have a digging rake on the front surface of their chelicerae. [Herbert W. Levi and Lorna R. Levi, "Spiders and Their Kin,", p. 20]

The about 10 mm long "Idioctis" builds its about 5 cm deep burrow just below tide level, and seals it with a thin trapdoor. The about 20 mm long "Sipalolasma" builds its burrow in rotted wood, with a hinged trapdoor at each end of the of burrow. [Murphy & Murphy 2000]

Like the Theraphosidae (tarantulas), they can run up glass. Some species can stridulate.

Distribution

Barychelids are found in South America, Africa, Madagascar, India, New Guinea, and Pacific islands.
