Atelognathus patagonicus occurs in the Laguna Blanca wetland system, in the province of Neuquén, northwestern Patagonia, Argentina (Cei, 1980). This Patagonian frog has shown a significant contraction of its original range, with a complete decline of the main population in Laguna Blanca lake. The decline of this formerly endemic species is one of the most dramatic examples of amphibian decline in the Patagonian fauna and it has been listed as threatened by the IUCN (2004). The introduction of perch is suspected to have contributed to the decline of Atelognathus patagonicus.
