GENUS Nesoryzomys

Author:Heller, 1904.
Citation:Proc. California Acad. Sci., 3: 241.
Type Species:Nesoryzomys narboroughi Heller, 1904 (= Oryzomys indefessus Thomas, 1899).
Comments:Oryzomyini. 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; Smith and Patton, 1999) and intimates that the group is an old Galapagos immigrant, originating ca. 3-3.5 million years ago (see Patton and Hafner, 1983). See Key and Heredia (1994) and Dowler et al. (2000) for recent assessments of conservation status, commensal rodent introductions, and natural history of populations on the various islands.
