The Psechridae are a family of spiders with about two dozen species in two orders.
They construct cribellate webs and are related to the Lycosidae. With body lengths of up to 2 cm and funnel webs more than 1 m in diameter, they are the biggest cribellate spiders. Psechrus species have been found in altitudes up to 2300 m in Taiwan. Female Psechrus carry their egg-sac in the chelicerae, similar to the ecribellate Pisauridae, with which they are closely related. They feature several characteristics normally found in ecribellate spiders, for example brood care behavior, and a colulus with no apparent function (Fang et al. 2000).

[edit] Habits
These cave dwelling spiders construct horizontal webs on the cave's ceiling and move below it. They have greatly elongated legs, with the last element being very flexible.
[edit] Distribution
They occur around the Pacific, for example in China, Myanmar, the Philippines and Thailand.
