The species is known from southern Peru (Junin, Cuzco, and Puno) and northern Bolivia (La Paz and Cochabamba). Recent published accounts from Peru only reported its presence in the Cordillera of Vilcabamba (Emmons et al. 2001), in the S of Manu (Pacheco et al. 1993), and in Machu Picchu (ParksWatch 2004). An ongoing survey in Peru has found the species in eleven new localities, within and outside protected areas of the southeastern Andes. Recent surveys in Bolivia found the species in a number of locations within protected areas along the Andes from La Paz to Cochabamba. Extent of occurrence extends for 83,000 km2. Ongoing geographic surveys in Peru (Barrio in prep.) will define more precisely the actual range, but most probably it will not increase significantly its extent of occurrence.
