Amphibia, Anura, Cycloramphidae, <i>Alsodes vanzolinii</i> (Donoso-Barros, 1974): Rediscovery in nature, latitudinal and altitudinal extension in Nahuelbuta Range, southern Chile

Abstract

New populations of the Critically Endangered anuran species Alsodes vanzolinii (Donoso-Barros 1974) werediscovered during two field surveys at Nahuelbuta Range, Biobío region, southern Chile. Adult specimens have not beenreported since the original description of the species heretofore. The new records provided herein extend the latitudinallimit of what was previously thought to be the only population of the species 40 km to the southwest, and the altitudinallimit from 25 m a.s.l. to 700 m a.s.l.
