Subfamily Calomyscinae Vorontsov and Potapova, 1979 . Zool. Zh., 58:1393.

COMMENTS: Although earlier authors associated it with New World sigmodontines, Vorontsov and Potapova (1979) recognized Calomyscus's combination of distinctive features by setting it apart as a tribe in the subfamily Cricetinae of the family Cricetidae . Pavlinov (1980c) kept it with sigmodontines, and Agusti (1989:387) summarily regarded it as the only living member of the Myocricetodontinae. Carleton and Musser (1984:313) discussed the different taxonomic assignments of Calomyscus, its characteristics that did not fit with Old World hamsters ( Cricetinae), and the dental similarities between Calomyscus and Miocene Democricetodon, and remarked that " Calomyscus could be justifiably classified among the cricetodontines, a group hitherto supposed extinct."
