Among them, the genus <i>Akodon</i> has been extensively analyzed with classical and molecular cytogenetics, which allowed the identification of a large number of intra- and interspecific chromosomal variation due to Robertsonian rearrangements, pericentric inversions, and heterochromatin additions/deletions. In order to shed some light on the cause of these rearrangements, we comparatively analyzed the karyotypes of three Akodontini species, <i>Akodon cursor</i> (2n = 14, FN = 19), <i>A. montensis</i> (2n = 24, FN = 42), and <i>Necromys lasiurus</i> (2n = 34, FN = 34), after GTG- and CBG-banding.
