ABSTRACT. A small linyphiid collection from Simushir Island contains 17 identified species, five of which are new to the Kurile list. Walckenaeria kochi (O. Pickard-Cambridge, 1872) is being found in East Siberia (east of Evenkia) for the first time. The status and affinities of Stemonyphantes sibiricus (Grube, 1861) are discussed. S. lineatus blauveltae Gertsch, 1951 is elevated in rank to full species (S. blauveltae stat.n.). It is found out that S. sibiricus and S. blauveltae are extremely close to each other, and can be separated by only one character in the male palp. Distribution of S. blauveltae is restricted only to the Nearctic.
