Crocidura shantungensis , Asian Lesser

White-Toothed Shrew

In 1934, Orii collected this species and Kuroda includ- ed it in C. dsnezumi as a subspecies ( Kuroda, 1934; Won, 1967). Jameson and Jones (1977) included C. dsnezumi in C. russula but Corbet (1978) treated C. dsnezumi as a separate species. Iwasa et al. (2001) treated the Jeju population as C. suaveolens but confusion with C. d. quelpartis and C. suaveolens may exist ( Motokawa et al., 2003). Motokawa et al. (2003) treated the Jeju population as a junior synonym of C. shantungensis . However, Jeju animals have distinct morphological variations (e.g., larger size) compared to those in the mainland population ( Motokawa et al., 2003). Wilson and Reeder (2005) refer to the possibility of subspecies of C. shantungensis . There is still controversy over the presence of C. dsinezumi on Jeju regardless of C. shantungensis . However, only C. shantungensis has been captured in recent surveys. Defining the subspecific level of Jeju’s population is necessary, unless 2 species in the genus Crocidura exist on the island.

This species inhabits various habitats from lowland to high mountains up to 1,100 m ( Won, 1967; Oh et al., 2007). There is constant home range that widens at the time of breeding season (H.S. Oh, Cheju National University, unpublished report).
