We investigated the morphological relationships among 8 populations of Sorex caecutiens/shinto group in East Asia using 11 cranial and dental characters and four external characters. Univariate and multivariate analyses of these characters failed to distinguish S. caecutiens and S. shinto. Morphological characters were, in fact, continuous between populations. Sorex shinto from Honshu was similar to S. caecutiens from the Korean peninsula and Primorye in skull dimensions and to S. caecutiens from Hokkaido-Sakhalin in external dimensions. Sorex caecutiens from Cheju Island is morphologically similar to S. shinto from Sado and Shikoku islands. These three insular populations were characterized by having large body size. Sorex caecutiens from Cheju was the largest of the S. caecutiens/shinto group in East Asia. This shrew from Cheju was classified definitively as S. caecutiens on DNA data but has a unique morphology among S. caecutiens populations in East Asia. We therefore regard this Sorex shrew on Cheju Island as a new subspecies of S. caecutiens and designate it S. c. hallamontanus ABE et OH.
