Clethrionomys rufocanus (Sundevall, 1846). Ofv. Kongl. Svenska Vet.-Akad. Forhandl. Stockholm, 3:122.

REVIEWED BY: M. Andera (MA).

TYPE LOCALITY: Sweden, Lappmark.

DISTRIBUTION: N. Palearctic from Scandinavia to Chukotka and to Mongolia, Transbaikalia, N.E. China; Korea; Kamchatka, Sakhalin (U.S. S.R.), Hokkaido and Rishiri Isl. (Japan).

COMMENT: Includes bedfordiae; see Gromov and Polyakov, 1977:147, and Corbet, 1978:99, but also see Imaizumi, 1972, Mem. Nat. Sci. Mus. Tokyo, 5: 131 -139. Includes montanus and rex; see Aimi, 1980, Mem. Fac. Sci. Kyoto Univ. Ser. BioL, 8:35-84. Corbet, 1978:99, tentatively included montanus in rex, which he listed as a species; Imaizumi, 1972, Mem. Nat. Sci. Mus. Tokyo, 5: 131-139, regarded both as distinct species; he believed them to be close to rufocanus, which also occurs on Hokkaido (as C. r. bedfordiae) and possibly Rishiri (as sikotanensis); also see Imaizumi, 1971, J. Mamm. Soc. Jpn., 5: 99-103. Revision of this species is needed for the Japanese, Korean, and Chinese forms; more than one species may be present (MLJ).
