Abstract

This paper is the first report of the freshwater mussel Margaritifera togakushiensis from northern Sakhalin. Species identification was performed based on shell characteristics. Twenty six dead shells and one live mussel were collected from the Dagi River in northern Sakhalin. One pair of the dead shells was regarded as M. togakushiensis, whereas all of the other specimens were Margaritifera laevis (Haas, 1910) [= Kurilinaia zatravkini (Bogatov, Prozorova & Starobogatov, 2003)]. The white-spotted char, which is the host of M. togakushiensis, lives abundantly in the Dagi River. All habitats of M. togakushiensis are located within the distribution area of the white-spotted char. Based on this relationship, it is possible that M. togakushiensis widely inhabits the northern part of the Russian Far East, as well as Sakhalin and Japan.
