Looks very much like Thomisus but with a round abdomen and no lateral eye projections. The dull brown colouration affords good camouflage for its more earthy lifestyle on the ground and under stones. Unlike Thomisus the male uses silk to secure the female to the substrate before mating. Ozyptila, Stiphropella, Stiphropus are other terrestrial genera.

Xysticus is derived from the Greek "Xysticus" means "scraping together" referring to its method of prey capture
