Akodon (Akodon) pervalens Thomas 1925

Akodon (Akodon) pervalens Thomas 1925 , Ann. Mag. Nat. Hist., ser. 9, 15: 579.

Type Locality: Bolivia, Tarija Dept., Caraparí, 1000 m.

Vernacular Names: Tarija Akodont.

Distribution: SC Bolivia, 900-2100 m (presumably into N Argentina).

Discussion: Subgenus Akodon . Status and relationship variously recognized: named as a subspecies of A. sylvanus by Thomas (1925; as followed by Musser and Carleton, 1993); reallocated to a subspecies of A. varius by Cabrera (1961); retained as a nominal species similar to A. cursor by Myers (1989); placed as a synonym of A. serrensis by Hershkovitz (1990 c). As dryly noted by Anderson (1997), who also listed pervalens as species, the want of unanimity in its treatment underlines the need for taxonomic resolution.
