BARYCHELIDAE Brush-footed trapdoors

Brush-footed trapdoor spiders have two short spinnerets at the rear of the abdomen, sometimes not projecting. They are small to large spiders capable of climbing smooth vertical surfaces with hairy feet. The head is often brown. If the head is black itoften has a brush of silvery hairs. The abdomen is often mottled brown, sometimes black and hairy, sometimes silver towards the front. Most of the world's Barychelids are found in Australia and on the islands Western Pacific, especially New Caledonia. They occupy most habitats, from rainforests to arid regions. Some species occupy the intertidal zone, in trees or in amongst the mangroves. Most have a door to their burrow, sometimes two. Some species build burrows on trees.
