SPECIES Sorex (Sorex) shinto

Author:Thomas, 1905.
Citation:Abstr. Proc. Zool. Soc. Lond., 1905(23): 19.
Common Name:Shinto Shrew
Type Locality:Japan, N Honshu, "Makado, near Nohechi".
Distribution:Honshu, Shikoku, and Sado (Japan).
Status:IUCN Endangered as S. sadonis; otherwise Lower Risk (lc).
Comments:Subgenus Sorex. S. caecutiens group. Karyotype has 2n = 42, FN = 70. Included in caecutiens by Abe (1967) and Corbet (1978c), but Imaizumi (1970b) treated shinto as a separate species, a view supported by Pavlinov and Rossolimo (1987), and by the allozyme data of George (1988). Ohdachi et al. (1997a) used mitochondrial gene sequences to show that both species occur in Japan: caecutiens in Hokkaido, and shinto in Honshu, Shikoku, and Sado. These authors also provided evidence that sadonis and shikokensis should be included in shinto; S. sadonis had been treated as a separate species before. Yoshiyuki and Imaizumi (1986) assigned the species to "the caecutiens arcticus section of the minutus group." Dokuchaev et al. (1999) studied the geographical variation of shinto and found that all three island populations are morphometrically distinct.
