Clethrionomys centralis Miller, 1906. Ann. Mag. Nat. Hist., ser. 7, 17:373. TYPE LOCALITY: Kazakhstan, W Tien Shan Mtns, Koksu valley, 9000 ft. DISTRIBUTION: Known only from Tien Shan Mtns, Kazakhstan and Kirghizia; and adjacent Xinjiang, China. SYNONYMS: frater. COMMENTS: A distinctive species recognized as such by Hinton (1926), included in C. glareolus by Corbet (1978c), and recognized again as separate (Corbet, 1984; Pavlinov and Rossolimo, 1987). Some Russian (Gromov and Polyakov, 1977) and Chinese (Ma et al., 1987) workers still use frater for the species. Chromosomal data recorded by Vorontsov et al. (1978) and Sokolov et al. (1990).
