Ctenomys population from Anillaco, La Rioja Province, Argentina has been the subjectof detailed studies of circadian rhythms, vocalization, ecology and spatial dynamics.However, the taxonomy and systematics of this population as well as populations ofCtenomys inhabiting Andean areas of this province is unknown. In this study, wepresent the phylogenetic relationship of the ?Anillaco tuco-tuco? as well as of two otherpopulations of Ctenomys, all distributed in the northern portion of La Rioja ProvinceArgentina. Based on molecular analyses and morphological comparisons, we reached tothe conclusion that the ?Anillaco tuco-tuco? population corresponds to the species C.famosus. In addition, an undescribed species, member of the ?mendocinus? lineage ofCtenomys, is recognized in the Andean portions of the province.
