SPECIES Oryzomys yunganus
| Author: | Thomas, 1902. | | Citation: | Ann. Mag. Nat. Hist., ser. 7, 9: 130. | | Common Name: | Amazonian Oryzomys | | Type Locality: | Bolivia, Cochabamba Dept., Charuplaya, 1350 m. | | Distribution: | Evergreen rain forest of Amazonia, sea level-2000 m, from Guianas and S Venezuela (Ochoa et al., 1988) to C Brazil, including lowlands and Andean foothills of C Colombia, E Ecuador, E Perú, and N Bolivia (see Musser et al., 1998:Fig. 14). | | Status: | IUCN – Lower Risk (lc). | | Comments: | Considered a subspecies of O. capito (= O. megacephalus) by Cabrera (1961); specific differences illuminated by Gardner and Patton (1976) and sustained by strong genetic divergence therefrom (Patton et al., 2000). Morphological definition, localization of type locality, and distributional limits provided by Musser et al. (1998), who noted substantial morphometric differentiation between western and eastern populations that may reflect separate species; also see Voss et al. (2001) for additional comments on this variation and for other comparisons with O. megacephalus. |
