Chaltenobatrachus grandisonae was first collected in Puerto Edén, Wellington Island, Magallanes Region, Chile, where the species has never been found again. Subsequently Basso et al. (2011) found it in two new localities in Lago del Desierto and Lago Nansen, Santa Cruz province, southern Patagonia, Argentina. Recently Cisternas et al. (2013) reported its presence in Laguna Caiquenes, Aysén Region, Chile. Our results provide distribution data between the northern and southern locations in Chile, and we confirm the presence of the species in Chilean Patagonia.
