Cansumys Allen, 1928 . J. Mammal., 9:244.

TYPE SPECIES: Cansumys canus Allen, 1928 .

COMMENTS: Listed as a synonym of Cricetulus by Ellerman (1941), Ellerman and MorrisonScott (1951), and Corbet (1978c) and of Tscherskia by Carleton and Musser (1984) and Pavlinov and Rossolimo (1987), but Cansumys does not belong with either of these. Its combination of pelage pattern, large body size, long tail, and high-crowned selenodont-like molars make it unique among cricetines (Ross, 1988).
