Graomys Thomas, 1916 . Ann. Mag. Nat. Hist., ser. 8, 17: 141.

TYPE SPECIES: Mus griseoflavus Waterhouse, 1837 .

COMMENTS: Phyllotine. Previously included in Phyllotis as a formal subgeneric division (Osgood, 1947; Pearson, 1958) or not (Hershkovitz, 1962). Returned to generic stature based on karyological data (Pearson and Patton, 1976) and other traits (see Reig, 1978; Olds and Anderson, 1989). Williams and Mares (1978) transferred Graomys pearsoni Myers, 1977, to Andalgalomys and synonymized G. hypogaeus in Eligmodontia typus .
