See text Xysticus is a genus of ground crab spiders described by C. L. Koch in 1835, belonging to the order Araneae, family Thomisidae.

The genus name is derived from the Ancient Greek root xyst, meaning "scraped, scraper".

Xysticus and Coriarachne are dark brown or reddish-brown crab spiders often encountered on weeds or trees.

They move slowly, and commonly hunt by stationing themselves in a high-traffic area and grabbing whatever arthropod passes close enough.

Also like most other Thomisidae, they seize prey with their enlarged anterior two pairs of legs and kill it by a venomous bite.
