Subterranean rodents Ctenomys are iconic representatives of the mammalian fauna from southern South America. Based on molecular data, eight lineages have been identified within the genus, although species-level identifications and relationships are still debated. Until now, the ?magellanicus? clade has been the only lineage mentioned from arid, extra-Andean portions of Patagonia. Here, we report the presence of a Ctenomys population from northern Patagonia that is unambiguously associated with the Central Argentinean ?mendocinus? lineage. Most of the 160,000 km2 comprising the northern portion of Patagonia ? an area consisting primarily of Monte Desert shrub-land ? are inhabited by Ctenomys populations of unknown taxonomy.
