Rediscovery of the mountain frog Telmatobius ceiorum (Anura: Telmatobiidae) in Argentina, last seen 40 years ago

Abstract

We report the rediscovery and the geographic occurrence extension of Telmatobius ceiorum, an endemic frog species from northern Argentina. This marks the first record of T. ceiorum since November 1984. The frogs were observed near the village of Hualinchay, Tucuman Province, at an elevation of 2060 m. The introduction of salmonids across much of its historical range is one of the main threats that may have contributed to the decline of T. ceiorum. Our findings emphasize the need for continued monitoring and conservation efforts for the species, particularly in light of the potential expansion of invasive fish species.
