 Apart from the southern big-eared brown bat, which lives in the same general locality, the Chilean myotis lives further south than any other bat species in the world.The species lives primarily in Chile, south of about 30°S, but is also found in the westernmost regions of the Argentinian provinces of Neuquén, Río Negro, and Chubut.At the extreme southern end of its range, it is found across Tierra del Fuego, in both the Chilean and Argentinian parts of the island.
