Lampshade spiders, familyHypochilidae, are among the most primitive ofaraneomorphspiders. There are twogenera and twelvespecies currently recognized. Likemygalomorphs, most hypochilids have two pairs ofbook lungs, but like araneomorphs they have intersecting fangs, with the exception of some species which have chelicerae in an angle that is neither orthognathous or labidognathous.[1] These long-legged spiders build typical "lampshade" style webs under overhangs and in caves. In theUnited States the fauna is primarily associated with theAppalachian,Rocky andCalifornia Mountains. Ten of the known species are found in these ranges, all in the genusHypochilus. The genusEctatosticta is found inChina.

In one analysis, the Hypochilidae are a sisterclade to theNeocribellatae, which contains all other spider species in theAraneomorphae (Coddington & Levi, 1991, p. 576). A more recent study groups them with theHaplogynae.[2]
