Арика-и-Паринакота
Telmatobius pefauri is a species of frog in the family Telmatobiidae. It is endemic to extreme northern Chile. It was already feared that this species is extinct, but recent research has suggested that the species is extant at several localities in the Arica y Parinacota Region, albeit at low numbers. Furthermore, morphological and genetic data suggest that "Telmatobius zapahuirensis" is a synonym of "Telmatobius pefauri". Common name Arico water frog has been coined for this species.
