Range: As the most common species of the Genus Sorex , S. caecutiens ranges throughout the Korean Peninsula and Jeju Island ( Jo et al. 2012 ; Fig. 15 ). It is locally abundant in the northeastern Korean Peninsula along higher mountain ranges ( Kim et al. 2015 ). Sorex caecutiens also inhabits the region near Seoul . Mt Odae and Mt. Jiri are known as habitats of this species in South Korea ( Yoon 1992 ). Remarks: The subspecific status of S . caecutiens in Korea remains ambiguous (S. c. annexus Jones and Johnson, 1960 ; S. c. macropygmaeus Miller, 1901 ). The first collection of Laxmann’s shrew on Jeju Island occurred in 1994 ( Ohdachi et al. 2003 ; Jo et al. 2012 ). Ten years later, Ohdachi et al . (2005) assigned a new Subspecies Sorex caecutiens hallamontanus Abe and Oh, 2005 , to the population on Jeju Island. The Jeju subspecies has morphological similarity with S . shinto , but DNA data grouped the Jeju subspecies with S . caecutiens ( Ohdachi et al . 2005 ) . Also, populations of S. caecutiens from Korea clustered with populations on Sakhalin Island based on cytochrome b analysis ( Ohdachi et al. 2003 ).
