Segestriidae
Tube-dwelling spiders (Segestriidae) are a family of araneomorph spiders first described by Eugène Simon in 1893. It consists of five genera, two large and widespread, '' Segestria'' and ''Ariadna'', and three smaller genera, '' Citharoceps'', '' Gippsicola'' and '' Indoseges''. They are haplogyne spiders, related to the Dysderidae and placed in clade or superfamily Dysderoidea. Members of this family are easily recognized because their first three pairs of legs are arranged forward instead of two and they have six eyes instead of eight, arranged in a semicircle. The leg structure appears to be an adaptation for living in silken tubes. Unlike those of the atypical tarantulas, these tubes may branch and are often built in tree bark fissures, as well as under stones. Both ''Segestria'' and ''Ariadna'' live in North America, South America, Eurasia, Africa and New Zealand, though ''Ariadna'' also lives in Australia. Genera , the World Spider Catalog accepts the following gen ...

Araneomorphae Genera
The Araneomorphae (also called the Labidognatha) are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This ''Atrax robustus'' shows the orientation of Myglamorphae fangs. Image:Che ...
