Neotoma Say and Ord, 1825 . J. Acad. Nat. Sci. Philadelphia, 4:345.

TYPE SPECIES: Mus floridana Ord, 1818 .

SYNONYMS: Homodontomys, Teanopus, Teonoma .

COMMENTS: Neotomine. Revised by Goldman (1910), then including only Homodontomys, Teonoma, and the nominate subgenus. Burt and Barkalow (1942) established current subgeneric framework, also relegating Hodomys and Teanopus to subgenera. See Birney (1976) and Mascarello (1978) for modifications of species-group associations since Goldman (1910). Phylogenetic relationships of the genus considered by Hooper and Musser (1964a) and Carleton (1980), who reinstated Hodomys as a genus (see above account); interspecific relationships evaluated by Carleton (1980) and Koop et al. (1985). Anatomical systems described by Arata (1964), Burt and Barkalow (1942), Carleton (1973, 1980), Hooper (1960), and Howell (1926a). Karyotypic variation and evolution assessed by Mascarello and Hsu (1976) and Koop et al. (1985).
