Folia Zool. Hydrob. Riga, 3:79 . TYPE LOCALITY: Russia , Caucasus, Stavropol Krai , Karachayevo-Cherkess Region, Karachayevsk District, Uchkulan (Utschkulak), Igera, 2100 meters; shown in Sokolov et al. (1989) . DISTRIBUTION: N Caucasus, north to Kursk District of S Russia ; see Sokolov et al. (1989). COMMENTS: Sokolov et al. (1989) distinguished this species from S. betulina primarily by its different karyotype. Pavlinov and Rossolimo (1987) tentatively listed S. strandi as a separate species, a hypothesis provisionally followed here. Further documentation and incorporation of other character sets is essential in order to assess whether or not strandi should be included in S. betulina .
