Abstract

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.
