We describe a new species of Selvasaura lizard from the western slopes of the eastern Andes of central Peru. Among other characters, the new species differs from congeners in having keeled dorsal scales and more transverse rows of scales on dorsum. We present a phylogeny as additional evidence supporting delimitation of the new species. Leer más.

Anurans of the family Centrolenidae are a highly diverse clade of Neotropical treefrogs. In the last two decades, glassfrogs have become a model system for studies in ecology and evolutionary biology, in part because their taxonomy and phylogenetic relationships are considered relatively well established.
