The genus name is derived from the Ancient Greek root ''xyst'', meaning "scraped, scraper". Description ''Xysticus'' and '' Coriarachne'' are dark brown or reddish-brown crab spiders often encountered on weeds or trees. While similar to the 'flower spiders', they tend to have shorter, sturdier legs. Many, but not all, species have abdomens more patterned than most ''Thomisus'' species, rather like some of the ''Synema'' species. Some however, that are more terrestrial, resemble earth in colour and texture. Most species of the genus Xysticus are small to medium sized spiders. They show a sexual dimorphism in size.

The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders. Description Members of this family of spiders do not spin webs, and are ambush predators. The two front legs are usually longer and more robust than the rest of the legs. The back two legs are smaller, and are usually covered in a series of strong spines. They have dull colorations such as brown, grey, or very bright green, pink, white or yellow. They gain their name from the shape of their body, and they usually move sideways or backwards.
