Reithrodontomys Giglioli, 1874. Bull. Soc. Geogr. Ital., Roma, 11:326.

TYPE SPECIES: Reithrodon megalotis Baird, 1858.

SYNONYMS: Aporodon, Ochetodon.

COMMENTS: Peromyscine. Alpha taxonomy revised by Allen (1895a), Howell (1914), and Hooper (1952), the last of whom framed the currently-used subgeneric division and species groupings. Distributions and species limits of Latin American harvest mice, especially those of the subgenus Aporodon, require renewed systematic attention. Generic relationships investigated by Carleton (1980), Hooper and Musser (1964a), and J. C. Patton et al. (1981). For comparative studies of morphology, see Arata (1964), Carleton (1973, 1980), and Hooper (1952, 1959); of karyology, see Carleton and Myers (1979), Engstrom et al. (1981), Hood et al. (1984), and Robbins and Baker (1980); of genic variation, see Nelson et al. (1984). A key to the species is found in Spencer and Cameron (1982).
