Lampshade spiders, family Hypochilidae, are among the most primitive of araneomorph spiders. There are two genera and twelve species currently recognized. Like mygalomorphs, hypochilids have two pairs of book lungs, but like araneomorphs they have intersecting fangs. 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, 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. 576). A more recent study groups them with the Haplogynae.〔 |p. 1766.〕 ==Species== ''Ectatosticta'' Simon, 1892 — China * ''Ectatosticta davidi'' (Simon, 1889) * ''Ectatosticta deltshevi'' Platnick & Jäger, 2009 ''Hypochilus'' Marx, 1888 — USA * ''Hypochilus bernardino'' Catley, 1994 * ''Hypochilus bonneti'' Gertsch, 1964 * ''Hypochilus coylei'' Platnick, 1987 * ''Hypochilus gertschi'' Hoffman, 1963 * ''Hypochilus jemez'' Catley, 1994 * ''Hypochilus kastoni'' Platnick, 1987 * ''Hypochilus petrunkevitchi'' Gertsch, 1958 * ''Hypochilus pococki'' Platnick, 1987 * ''Hypochilus sheari'' Platnick, 1987 * ''Hypochilus thorelli'' Marx, 1888 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lampshade spider」の詳細全文を読む スポンサード リンク
