Abrothrix xanthorhina is in the subgenus Angelomys. Several nominal forms have been subsumed under A. xanthorhina, including among those originally proposed as species, Akodon (Akodon) lanoi (with type locality in de los Estados Island) and Akodon (Akodon) hershkovitzi (Capitan Aracena Island). Taxonomy of A. xanthorhina remains poorly explored and needs an urgent fresh integrative approach. Monotypic.
