Graomys edithae Thomas, 1919 . Ann. Mag. Nat. Hist., ser. 9, 3:495.

TYPE LOCALITY: Argentina, La Rioja Prov., Otro Cerro, about 18 km NNW Chumbicha, 3000 m .

DISTRIBUTION: Known only from the type locality.

COMMENTS: Status uncertain—placed as a synonym of G. griseoflavus by Cabrera (1961) or retained as a nominal species of Phyllotis (Hershkovitz, 1962) or of Graomys (Myers, 1977; Williams and Mares, 1978). Reinvestigation of the original type series, reportedly acquired in near sympatry with cachinus and médius (Thomas, 1919), would shed much light.
