Zool. Beitr., Vol. 47: 220 . Type Locality: Brazil , Minas Gerais , Pico da Bandeira, W slope Mt Caparaó, Arrozal, 2300 m . Vernacular Names: Caparao Akodont . Distribution: Known only from highland localities, 2000-2700 m, in Minas Gerais and Rio de Janeiro , SE Brazil . Discussion: Subgenus Akodon , A. boliviensis species group ( Hershkovitz, 1990 c ) or A. cursor species group ( Geise et al., 2001 ). Described as related to A. sanctipaulensis , A. lindberghi , and A. azarae ( Hershkovitz, 1998 ) , but gene-sequence data suggest closer affinity to A. cursor and A. montensis ( Geise et al., 2001 ) . Status with respect to A. paranaensis and to A. reigi , which are morphologically very similar and have the same diploid number ( Christoff et al., 2000 ; González et al., 1998), should be reviewed and their morphological definition and distributional limits as three separate species verified.
