Oryzomys melanotis Thomas 1893

Oryzomys melanotis Thomas 1893, Ann. Mag. Nat. Hist., ser. 6, 11: 404.

Type Locality: México, Jalisco State, Mineral San Sebastián.

Vernacular Names: Black-eared Oryzomys.

Synonyms: Oryzomys colimensis Goldman 1918 .

Distribution: Low to intermediate elevations of W México, from S Sinaloa to SW Oaxaca.

Conservation: IUCN – Data Deficient.

Discussion: Revised by Goldman (1918), who recognized melanotis and rostratus as separate species within a melanotis species group. Hooper (1953) viewed the geographic complementarity of the two as a subspecific pattern, and so they were recognized by Hall and Kelson (1959) and Hall (1981). Engstrom (1984) returned rostratus to a separate species based on a robust variety of data interpreted within a zoogeographic context.
