Cybaeidae is a family of spiders first described by Nathan Banks in 1892.[1] There are small to large sized entelegyne spiders, which are ecribellate.[2] The diving bell spider or water spider Argyroneta aquatica was previously included in this family, but is now in the family Dictynidae.[3][4] The distribution of this species resembles closely a typical Holarctic biogeography, with all of their species being found in the northern hemisphere. Where they have a tendency to live beneath rocks or woody debris in shaded and cool forest habitats, but they can also be found in caves, ant nests, and moss on tree trunks.[2] They are morphologically defined as spiders which have three claws, a single row of tarsal trichobothria, and posterior lateral spinnerets which lack a cribellum.[2]

Most of the cybaeid genera are very species rich, as they have a large number of very short-range endemic species.[2]

Genera
