SPECIES Caryomys eva

Author:Thomas, 1911.
Citation:Abstr. Proc. Zool. Soc. Lond., 1911(90): 4.
Common Name:Eva’s Red-backed Vole
Type Locality:China, Gansu (Kansu), SE of Tauchow, 10,000 ft (3028 m).
Distribution:China, mountains of S Gansu and adjoining Shaanxi, Sichuan, and Hubei, 2400-3600 m; Zhang et al. (1997) included Ningxia and Qinghai provinces in the distribution.
Status:IUCN – Lower Risk (lc) as Eothenomys eva.
Comments:Listed as a member of Evotomys or Clethrionomys rufocanus by Hinton (1926a), Ellerman and Morrison-Scott (1951), and Gromov and Polyakov (1977). Correctly acknowledged and revised as a species (of Eothenomys) by G. M. Allen (1940), Corbet (1978c), Corbet and Hill (1992), and Kaneko (1992c), as followed by Musser and Carleton (1993) and Pavlinov et al. (1995a). Phallic morphology described by Yang et al. (1992) and contrasted with species of Eothenomys. Corbet and Hill (1992) noted that the southern populations (alcinous) have much darker upperparts and underparts than the slight frosting of typical eva. Kaneko’s (1991) morphometric analysis associated the holotypes of alcinous and aquilus among samples of eva.
