Oryzomys saturatior Merriam, 1901 . Proc. Washington Acad. Sci., 3:290.

TYPE LOCALITY: Mexico, Chiapas, Tumbala, 5000 ft .

DISTRIBUTION: Cloud forest elevations from S Oaxaca and Chiapas, Mexico, through Guatemala, Honduras, and El Salvador, to NC Nicaragua.

SYNONYMS: hylocetes .

COMMENTS: Described as a subspecies of O. chapmani (Merriam, 1901) and later retained as a subspecies of O. alfaroi (Goldman, 1918; Hall and Kelson, 1959). In our revision (in prep.) of the alfaroi complex we view the divergence of chapmani and saturatior, whose ranges are separated by the Isthmus of Tehuantepec, as sister species.
