Abstract: In September 2017, five shrew specimens were collected in Xingshan county, Hubei province, central China. Being dark grey, each shrew specimen has small body size (71.72±3.49, 67.19-77.01 mm), and a long two-color tail (52.39±1.37, 53.11-53.22 mm) with obvious hair. The cranium is flat and slightly firm, having an evident herringbone ridge, with a blunt snout. The phylogenetic relationship was reconstructed by Bayesian inferences based on the mitochondrial cytochrome b gene sequence, combined with the homologous sequences of seven Crocidura species retrieved from NCBI database. In the phylogenetic tree, these individuals clustered with C. tanakae, and they combined into a monophyletic clade. Furthermore, they have the closest genetic distance with C. tanakae compared with the other species. According to the morphological and phylogenetic evidence, the collected specimens were identified as the Taiwanese grey shrew (C. tanakae), which were recorded for the first time in Hubei province, China. The sample sites in this study, located in the northmost distribution area of C. tanakae to date, covered diverse habitats, including farmland, deciduous broad-leaved forests, evergreen broad-leaved forests and shrubs. This discovery extends the previous species ranges to a larger scale and contributes profound implications for its biogeographic distribution.
