Oligoryzomys flavescens (Waterhouse 1837)

[Oligoryzomys] flavescens (Waterhouse 1837) , Proc. Zool. Soc. Lond., 1837: 19.

Type Locality: Uruguay, Maldonado Dept., Maldonado.

Vernacular Names: Flavescent Colilargo.

Synonyms: Oligoryzomys antoniae (Massoia 1979) ; Oligoryzomys occidentalis Contreras and Rosi 1980 .

Distribution: E Paraguay ( Bonvicino and Weksler, 1998), SE Brazil (Rio Grande do Sul to Bahia), Uruguay, and N to SC Argentina; range limits uncertain.

Conservation: IUCN – Lower Risk (lc).

Discussion: Chromosomal variation reported and taxonomic implications discussed by Sbalqueiro et al. (1991); allozymic polymorphisms and gene flow among populations distributed along the lower Río Paraná, EC Argentina, discussed by Chiappero et al. (1997). Morphometrically ( Myers and Carleton, 1981) and karyotypically ( Sbalqueiro et al., 1991) similar to O. fornesi ; their level of differentiation deserves further illumination (see next). In their informal review, Carleton and Musser (1989) acknowledged three flavescens like forms from Peru, Bolivia, and Brazil; these morphs should be critically identified, and named as necessary, as part of a much-needed revision of flavescens .
