Abstract: Ozyptila balcanica sp. n. is described (based on both males and females) from Bulgaria (Zemen Gorge), (Arkadia, Mainalo) and FYR Macedonia (Skopje Region, Osogovo Mts.). The new species re- sembles the poorly known O. umbraculorum Simon, 1932, recorded from , and , but is clearly a distinct species. Illustrations of both taxa are presented. Due to the isolated position of both species in the , we proposed a new species group – umbraculorum, characterised by a large inter- mediate apophysis (ITA), armed with well-developed teeth, and a long scimitar-shaped tegular apophysis. The females have similar epigynes with pan-shaped median septum.
