Caryomys inez (Thomas 1908)

[Microtus (Eothenomys)] inez Thomas 1908 , Abstr. Proc. Zool. Soc. Lond., 1908 (63): 45.

Type Locality: China, Shanxi (Shansi), mtns 12 mi (19 km) NW Kolanchow, 7000 ft (2134 m).

Vernacular Names: Inez's Red-backed Vole.

Synonyms: Caryomys nux (Thomas 1910) .

Distribution: N Sichuan and SE Shaanxi through Shanxi provinces, China, possibly farther east.

Conservation: IUCN – Lower Risk (lc) as Eothenomys inez .

Discussion: Following Hinton (1926 a), inez was synonymized with Clethrionomys rufocanus ( Ellerman and Morrison-Scott, 1951; Gromov and Polyakov, 1977), but its distinctive status is well documented, typically within Eothenomys (G. M. Allen, 1940; Corbet, 1978 c; Corbet and Hill, 1992; Kaneko, 1992 c). Hinton (1926 a) and Ellerman and Morrison-Scott (1951) allocated nux to Clethrionomys rufocanus shanseius , but G. M. Allen (1940) treated it as a subspecies of Eothenomys inez . Kaneko’s (1991) morphometric analysis identified the holotype of nux as an example of inez , as concluded earlier by A. B. Howell (1929). Kaneko restricted the range to Shaanxi and Shanxi provinces, but Zhang et al. (1997) mapped a far broader distribution.
