Akodon sylvanus Thomas, 1921. Ann. Mag. Nat. Hist., ser. 9, 7:184. TYPE LOCALITY: Argentina, Jujuy Prov., Sierra de Santa Barbara, Sunchai, 1200 m. DISTRIBUTION: NW Argentina. SYNONYMS: pervalens. COMMENTS: Subgenus Akodon. Retained as a species until Cabrera (1961) synonymized it as a race of A. azarae; Myers (1989) tentatively listed sylvanus and azarae as separate species. The status and relationship of pervalens deserves resolution: retained as a nominal species similar to A. cursor by Myers (1989); placed as a synonym of A. serrensis by Hershkovitz (1990c). Arrangment here follows the describer, Thomas (1925).
