A new species of red-toothed shrew belonging to the caecutiens-arcticus section of the Sorex minutus group is described from Sado Island, under the name Sorex sadonis, The species is similar to Sorex arcticus KERR, 1792 in having a large skull and massive teeth, but the 2nd lower tooth has a secondary cusp and the lateral pelage is much darker than the ventral. This species is easily distinguished from Sorex shinto shinto THOMAS, 1905 from Honshu, Sorex shinto saevus THOMAS, 1907 from Hokkaido, and Sorex shinto shikokensis ABE, 1967 from Shikoku, Japan, by the much bigger claws of the forefoot and the decidedly darker coloration.
