Birch mice are grouped under the monotypic genus Sicista Gray, 1827 with 14 recognized species currently distributed over the Palearctic realm (Holden et al. 2017). The genus was earlier variably placed under the families Dipodidae of subfamily Sicistinae (Ellerman 1961; Ellerman & Morrison-Scott 1966; Holden & Musser 2005) and Zapodidae (Corbet & Hill 1992) but at present it is accommodated under the family Sminthidae of superfamily Dipodoidea (Holden et al. 2017). The Chinese Birch Mouse Sicista concolor Buchner, 1892 is a montane species with three fragmented populations reported so far, the nominate subspecies S. c. concolor Buchner, 1892 reported from northcentral China, S. c. leathemi (Thomas, 1893) including Sicista concolor flavus (True, 1894) from India (Jammu & Kashmir, Ladakh), western China (southwestern Xinjiang), & northern Pakistan (Kaghan valley), and S. c. weigoldi Jacobi, 1923 from southcentral China (Holden et al. 2017). © Talmale et al. 2021.
