本研究利用核型与形态学特徴，探讨台湾白齿鼩的种界。从台湾各地获得九十九只动物，捕获率通常低于10%。三个物种被不同的细胞型识别：Crocidura attenuata tanakae 2n = 40，FN = 56; Crocidura suaveolens hosletti 2n = 40，FN = 50; Crocidura kurodai 2n = 40，FN = 54。一套六个形态特征诊断的三个物种：头骨的形状，位置的切牙孔，形状的第四上前磨牙，形状的耳廓，尾触须，和脚垫。提供了一个物种检索表和每个物种的生活史注释。最后，我们讨论了东亚和东南亚地区的鳄鱼属的染色体进化和进化。
We define the species boundaries of white-toothed shrews (genus Crocidura) in Taiwan using karyological and morphological characteristics. Ninety-nine animals were obtained from all over Taiwan at capture rates usually less than 10%. Three species are recognized by distinct cytotypes: Crocidura attenuata tanakae 2n = 40, FN = 56; Crocidura suaveolens hosletti 2n = 40, FN = 50; Crocidura kurodai 2n = 40, FN = 54. A suite of six morphological characters diagnose the three species: shape of skull, position of incisive foramina, shape of fourth upper premolar, shape of pinna, tail vibrissae, and foot pads. A species key and notes on the life history of each species are provided. Finally, we discuss chromosomal evolution and biogeography of Crocidura in East and South East Asia.
