Ariamnes (spider)

Ariamnes is a genus of comb-footed spiders (family Theridiidae) that was first described by Tamerlan Thorell in 1869. Some species have greatly elongated abdomens, making them resemble a twig.

Life style

These spiders are mostly free-living, at least as adults, although a number have been found to occur as kleptoparasites on the webs of other spiders, at least facultatively. They are nocturnal. The egg sac is elongated. They are rare and little is known about them in South Africa.

Taxonomy

Ariamnes was removed from the synonymy of Argyrodes by Agnarsson in 2004.
