Abstract

Geographic variation of the mole-shrew, Anourosorex squamipes Milne-Edwards, 1872 (Mammalia: Insectivora: Soricidae) was examined on the basis of 18 cranial morphometric characters of 112 specimens collected from the provinces of Sichuan and Yunnan in China, and from northern Vietnam, Assam, and Taiwan by using univariate and multivariate statistics. The Assam sample was larger in overall dimensions than those from Sichuan, Yunnan, Vietnam, and Taiwan. The Taiwan sample differed from other samples in its proportions. Three allopatric forms were recognized and assigned subspecific status: populations of Sichuan, Yunnan, Vietnam, Myanmar, and Thailand were assigned to A.s. squamipes; populations in Assam south of the Bramaputra River were assigned to A.s. assamensis Anderson, 1875; and populations in Taiwan were assigned to A.s. yamashinai Kuroda, 1935. Anourosorex s. schmidi Petter, 1963 from Bomdila in Assam north of the Bramaputra River was tentatively retained as a fourth subspecies.
