Taxonomy. Cricetulus sokolovi Orlov & Malygin, 1988 View in CoL , SW shore of Lake Orog Nuur, Bayan Hongor, W Mongolia.

Cricetulus sokoloviis in the barabensis species group. It was formerly united with C. barabensis but raised to full species status based on chromosomal and pelage characteristics described by V. N. Orlov and V. M. Malygin in 1988. Samples from Mongolia that had been identified as C. obscurus are now considered synonymous with C. barabensis .

Monotypic.

Distribution. Mongolia and N China (Inner Mongolia [= Nei Mongol]). View Figure
