Montane Oldfield Mouse
French: Thomasomys de montagne / German: Bolivien-Paramomaus / Spanish: Raton de erial de montana
Other common names: Montane Thomasomys
Taxonomy. 7 Thomasomys oreas Anthony, 1926 View in CoL , “Cocopunco, about 80 miles [= 129 km] north of La Paz, Bolivia, altitude 10,000 feet [= 3048 m].”
Considerable geographic and intraspecific variation suggests that 7. oreas represents a species group that includes at least three species, but additional taxonomic research is required. Here treated as monotypic.
Distribution. Andes from N Peru, S of the Rio Maranon, to C Bolivia. View Figure
