Euneomys Coues, 1874 . Proc. Acad. Nat. Sci. Philadelphia, 26:185.

TYPE SPECIES: Reithrodon chinchilloides Waterhouse, 1839 .

SYNONYMS: Bothriomys , Chelemyscus .

COMMENTS: Phyllotine. Few specimens exist to substantiate the specific taxonomy and distribution of the genus. Revised by Hershkovitz (1962), who acknowledged several nominal species but indicated their probable synonymy under E. chinchilloides , as Mann (1978) so formalized for Chilean populations. Yanez et al. (1987) summarized extant specimen data for Euneomys and concluded that one species is represented. Others have recognized two or more (e.g., Osgood, 1943; Pearson and Christie, 1991; Pine et al., 1979). The latter arrangement is more nearly correct but must be sustained within the context of rigorous revisions. Holotype of Reithrodon fossor Thomas, 1899 , type species of Chelemyscus Thomas, 1925 , is a composite, the designated type skull referrable to Euneomys ( Osgood, 1943: 164; Pearson, 1984:231).
