Chimarrogale himalayica was considered as widely distributed from South Himalaya, through southern China to eastern China, across Oriental and Palearctic Regions. Two subspecies including C. h. himalayica and C. h. leander were recognized, but the latter one was recognized as a distinct species genetically sister to C. platycephala from Japan. The distributional boundary between himalayica and leander remains unclear because of the lack of voucher specimen and genetic material. Chimarrogale specimens were obtained during recent fieldworks in Sichuan (32°35'45.6"N, 104°43'26.4"E), Zhejiang (29°12'17.9"N, 120°30'57.6"E) and Hunan Provinces (30°0'54.3"N, 110°46'58.8"E; 29°38'60"N, 109°40'48.0"E), and these specimens could be safely assigned to C. leander based on phylogenetic analysis using the complete cytochrome b gene. We examined specimens deposited in museums, compared the external morphology. Our revision suggested the distribution of C. leander in Fujian, Guangxi, Guizhou, Hubei, Hunan, Shaanxi, Sichuan, Taiwan and Zhejiang, most provinces in the southeastern China. The distribution of C. himalayica in China is only confirmed in Yunnan, although it may be distributed in southern Tibet. The distribution pattern is likely shaped by the topographic structure in China, which led to geographic isolation and allopatric speciation.

利安德水鼩很长时间被认为是喜马拉雅水鼩的亚种,但近年来的研究发现利安德水鼩是进化关系上与日本水鼩更加接近的独立物种。而喜马拉雅水鼩一直被认为是分布区横跨古北界和东洋界广域分布的物种,但基于Cyt b基因序列测定和系统进化关系的构建,我们确定最近在四川、浙江和湖南等地采集的水鼩标本均为利安德水鼩。基于基因序列和对馆藏标本的比对,我们修订喜马拉雅水鼩和利安德水鼩在中国的分布。四川、湖北、湖南、陕西、贵州、广西、福建、台湾、浙江等地区都是利安德水鼩的分布区,而喜马拉雅水鼩在中国确定的分布区仅在云南。这一分布格局很可能是由于在地形地貌的影响下产生隔离分化的结果。
