Treatment

Oligoryzomys griseolus Osgood 1912 , Field Mus . Nat. Hist. Publ., Zool. Ser., 10: 49.

Type Locality: Venezuela, Táchira State, upper Río Táchira, west of Páramo de Tamá, 6000-7000 ft (1830-2130 m).

Vernacular Names: Grizzled Colilargo.

Distribution: Táchira Andes of extreme W Venezuela and Cordillera Oriental of E Colombia.

Conservation: IUCN – Lower Risk (lc).

Discussion: As noted by Osgood (1912) and verified by specimens in USNM, this distinctive form contrasts sharply with neighboring populations of O. fulvescens (e.g., navus and tenuipes ) and instead resembles O. vegetus of lower Middle America.
