Pitymys leucurus (Blyth, 1863) . J. Asiat. Soc. Bengal, 32:89.

TYPE LOCALITY: India, Ladak, near Lake Chomoriri (=Tsomoriri) .

DISTRIBUTION: Tsinghai, Sinkiang, and Tibet (China) (SW), and the Himalayas west to Kashmir.

COMMENT: Subgenus Phaiomys; see Chaline, 1974; or subgenus Neodon; see Gromov and Polyakov, 1977:252. Corbet, 1978:107, included strauchi, which Van der Meulen, 1978, Ann. Carnegie Mus., 47:101- 145, listed as a distinct species. If Pitymys were considered a subgenus of Microtus, leucurus would be preoccupied by leucurus Gerbe, 1852, now included in M. nivalis; M. leucurus Blyth would then be called M. blythi (Blanford, 1875) (WDS). Martin, R. A., 1974, in Webb, ed., Pleistocene Mammals of Florida, p. 60, considered Phaiomys a distinct genus. Includes fuscus, considered a separate species of Microtus (Lasiopodomys) by Zheng and Wang, 1980, Acta Zootax. Sin., 5(l):106— 111; but also see Corbet, 1978:107.
