'''Lampshade spiders''', family '''Hypochilidae''', are among the most primitive of [[araneomorph]] [[spider]]s. There are two [[genus|genera]] and twelve [[species]] currently recognized. Like [[mygalomorph]]s, most hypochilids have two pairs of [[book 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.<ref>[https://books.google.com/books?id=rc6Vz-cWickC&dq=%22exactly+intermediate+between+Mygalomorphae+and+Araneomorphae%22&pg=PA418 Spiders--webs, Behavior, and Evolution]</ref> These long-legged spiders build typical "lampshade" style webs under overhangs and in caves. In the [[United States]] the fauna is primarily associated with the [[Appalachian Mountains|Appalachian]], [[Rocky Mountains|Rocky]] and [[California]] Mountains. Ten of the known species are found in these ranges, all in the genus ''Hypochilus''. The genus ''Ectatosticta'' is found in [[China]].

In one analysis, the Hypochilidae are a sister [[clade]] to the [[Neocribellatae]], which contains all other spider species in the [[Araneomorphae]] (Coddington & Levi, 1991, p.&nbsp;576). A more recent study groups them with the [[Haplogynae]].<ref>{{Cite journal |last1=Bond |first1=Jason E. |last2=Garrison |first2=Nicole L. |last3=Hamilton |first3=Chris A. |last4=Godwin |first4=Rebecca L. |last5=Hedin |first5=Marshal |last6=Agnarsson |first6=Ingi |year=2014 |title=Phylogenomics Resolves a Spider Backbone Phylogeny and Rejects a Prevailing Paradigm for Orb Web Evolution |journal=Current Biology |volume=24 |issue=15 |pages=1765–1771 |doi=10.1016/j.cub.2014.06.034 |name-list-style=amp |pmid=25042592|doi-access=free }}<!--|access-date=2015-09-23 --> |p. 1766.</ref>
