Abstract


Two species of the genus Xysticus from Korea are revised with detailed illustrations, spination of each leg, trichobothrium patterns and SEM photographs. The female of X. concretus Utochkin, 1968 is described for the first time and Xysticus lepnevae Utochkin, 1968 from Korea represent the species’ southernmost known records. The latter species is distinguished by its male palpal organs with hooked median apophysis, developed ventral tibial apophysis and expanded retrolateral tibial apopysis, two tegular sutures and by it epigynum with triangular atrium and large copulatory ducts circled, with broadly transparent membrane. Furthermore, the Xysticus spiders, previously misidentified in Korea as male of X. dichotomus Paik, 1973 and female of X. bifurcus Paik, 1973 are in fact the true X. concretus.
