Sitticus ranieri Peckham & Peckham and S. saxicola (C. L. Koch) constitute a close group of species due to the morphology of their copulatory organs. Re-examination of specimens previously identified as Sitticus saxicola from Fennoscandia has revealed that they belong to S. ranieri. Redescriptions with illustrations of both species are provided. S. saxicola has a disjunct distribution, occurring in mainly montane areas in the central parts of Europe and on the Balkan peninsula, as well as in the Russian Far-East (known from Sakhalin). S. ranieri shows a wide, hypoarcto-boreal distribution throughout northern Europe and Siberia, extending into North America. North American males of S. ranieri from southern British...
