Graomys griseoflavus (Waterhouse 1837)

[Mus] griseoflavus Waterhouse 1837, Proc. Zool. Soc. Lond., 1837: 28.

Type Locality: Argentina, Río Negro Prov., mouth of Río Negro.

Vernacular Names: Common Pericote.

Synonyms: Graomys cachinus (J. A. Allen 1901); Graomys chacoensis (J. A. Allen 1901); Graomys lockwoodi Thomas 1918; Graomys medius Thomas 1919 .

Distribution: SC Bolivia, W Paraguay, and nearby Brazil, south through W Argentina to S Chubut Prov.

Conservation: IUCN – Lower Risk (lc).

Discussion: See remarks under G. centralis and G. domorum, taxa formerly included under G. griseoflavus as revised by Hershkovitz (1962). Pardiñas (1995) reallocated the late Pleistocene forms Bothriomys catenatus and Oxymicterus impexus, described by Ameghino (1889), as full synonyms of G. griseoflavus; these reallocations and other fossil sites in Buenos Aires establish the broader distribution of the species in the late Pleistocene.
