Microtus juldaschi (Severtzov, 1879) . Sap. Turk. Otd. Obsh. Lubit. Estestv., 1:63.

TYPE LOCALITY: Kirghizia, Kara Kul Lake basin, near Aksu .

DISTRIBUTION: Tien Shan and Pamir Mtns in Kirghizia and Tadzhikistan west to about Samarkand, south to NE Afghanistan and N Pakistan ( Roberts, 1977), and east to NW Xizang (Tibet) (see Feng et al., 1986; Niethammer, 1970).

SYNONYMS: Carruthers, pamirensis .

COMMENTS: Subgenus Neodon , a member of its own species group ( Zagorodnyuk, 1990). The status of the distinctive Carruthers is unresolved: treated as a separate species ( Ellerman and Morrison-Scott, 1951; Ognev, 1964); then synonymized with juldaschi ( Corbet, 1978c) ; and listed as a synonym of the latter but with question ( Gromov and Polyakov, 1977; Pavlinov and Rossolimo, 1987). Chromosomal analyses by Gileva et al. (1982) revealed two distinctive groups, which they considered to be two species but with probable different boundaries than usually described for juldaschi and Carruthers.
