Oreobates berdemenos

This species is similar to others in the genus Oreobates, of which O. barituensis and O. discoidalis also live in the forests of the Southern Andean Yungas. Oreobates berdemenos was identified by a combination of morphological characteristics and supported by molecular evidence (DNA sequences), both in terms of genetic distance and phylogenetic analysis. The two other Argentine species in the genus are identifiable due to their abdominal (or disc-like) folds, which O. berdemenos lacks. They have different tympanums and markings, among other more subtle differences. As a member of the clade Terrarana, it exhibits direct development; adult females lay eggs that metamorphose into juveniles, an atypical feature in amphibians, which commonly go through an intermediate tadpole stage.

This species inhabits the mountain forests in the Southern Andean Yungas ecoregion. It is found in the province of Jujuy, in northwestern Argentina.
