[[File:Ground crab with egg sac.jpg|thumb|Female ''Xysticus'' sp. with egg sac]]
'''''Xysticus''''' is a genus of ground [[Thomisidae|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".
==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. Females of typical species reach a maximum of {{convert|10|mm}} of body length, while their males are about {{convert|3|-|5|mm}} long, about half the size of the females.
The basic colour of these species is usually brown, beige or gray. The [[prosoma]] is sometimes slightly smaller than the [[opisthosoma]]. In many species the front body shows in the middle a broad, pale longitudinal band. The [[opisthosoma]] is clearly flattened in most species and shows a median broad and dark leaf marking.
The species are often very similar to each other, and in most cases can be distinguished only by a microscopic examination of the reproductive organs.
==Behaviour==
The spiders of the genus ''Xysticus'' do not build webs; like most Thomisidae they are ambush hunters and prefer to hunt near the ground (hence the common name "ground crab spiders"). 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.
