Treatment

Nesoryzomys Heller, 1904 . Proc. California Acad. Sci., 3:241.

TYPE SPECIES: Nesoryzomys narboroughi Heller, 1904 (= Oryzomys indefessus Thomas, 1899 ).

COMMENTS: Oryzomyine. Realigned as a subgenus of Oryzomys by Ellerman (1941), following the comments of Goldman (1918). Morphological, genic, and karyological information, however, sustains the generic separation of Nesoryzomys ( Beaufort, 1963; Gardner and Patton, 1976; Patton and Hafner, 1983) and intimates that the group is an old Galapagos immigrant, originating ca. 3-3.5 mya (see Patton and Hafner, 1983).
