Tube-dwelling spider

Tube-dwelling spiders (Segestriidae) is a family of araneomorph spiders first described by Eugène Simon in 1893.[1] It consists of four genera, two large and widespread, Segestria and Ariadna, and two smaller genera, Citharoceps and Gippsicola.[2] They are haplogyne spiders, related to the Dysderidae and placed in clade or superfamily Dysderoidea.

Diversity
4 genera, 160 species

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.[1] 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.[2]

gollark: also <#471334670483849216> probably, the slightly more accepted place for politics things.
gollark: That's irrelevant, and probably only is true if you define the terms very oddly anyway.
gollark: We used to have a political-infighting. Also I have no idea why "derp" brought "evolution" into "this" but it's probably irrelevant.
gollark: I just don't think that centrally planned systems are computationally feasible, manage information flow well, or are generally very reasonable. (also centralization of power is not very good politically)
gollark: Bees means bees, as in bees or orbital bee strike.
