Akodon mimus (Thomas, 1901) . Ann. Mag. Nat. Hist., ser. 7, 7:183.

TYPE LOCALITY: Peru, Puno Dept., Limbane, 2600 m .

DISTRIBUTION: E Andean slopes of SE Peru to WC Bolivia.

COMMENTS: Type species of Microxus, a taxon arranged either as a subgenus of Akodon (Cabrera, 1961), as a distinct akodontine genus (Ellerman, 1941; Gyldenstolpe, 1932; Reig, 1987; Thomas, 1916c), or as a synonym of the oxymycterine genus Abrothrix (Hershkovitz, 1966c) . Preliminary electrophoretic evidence indicates that mimus is phyletically closer to species of Akodon sensu stricto than to those of Bolomys or Chroeomys (see Patton et al., 1989; Smith and Patton, 1991). Also see remarks under A. bogotensis.
