This study investigated geographic variation in the Asian lesser white-toothed shrew, Crocidura shantungensis Miller, 1901, among a number of localities in East Asia, including the Korean Peninsula, Tsushima Island, Cheju Island, and Taiwan, using univariate and multivariate analyses of cranial morphometric characters. Sexual differences were found in Taiwanese shrews, but were not evident in those from Korea or Tsushima. The samples from Taiwan had a larger overall cranial size than those from Korea and Tsushima, and were well separated from the latter two samples in the discriminant analyses. The overall size of the Cheju shrews was also greater, but lay within the variation of those from Taiwan. Crocidura dsinezumi quelpartis Kuroda, 1934, described from Cheju Island, is actually a junior synonym of C. shantungensis, and is not related to C. dsinezumi.
本研究利用颅骨形态测量特征的单变量和多变量分析，调查了1901年命名的亚洲小麝鼩（Crocidura shantungensis Miller）在东亚多个地区的地理变异情况，这些地区包括朝鲜半岛、对马岛、济州岛和台湾。在台湾的麝鼩中发现了性别差异，但在来自韩国或对马岛的麝鼩中并不明显。来自台湾的样本总体颅骨尺寸比来自韩国和对马岛的样本大，并且在判别分析中与后两个样本有明显区分。济州岛麝鼩的总体尺寸也较大，但处于台湾麝鼩的变异范围内。1934年从济州岛描述的Crocidura dsinezumi quelpartis Kuroda实际上是C. shantungensis的次异名，与C. dsinezumi无关。
