Resumen

The gymnophthalmid Andean lizards of the genus Proctoporus (Gymnophthalmidae, Cercosaurinae) are semifossorial species that inhabit the montane forests, inter-Andean valley, and humid grasslands across the Cordillera de los Andes from Peru to Argentina. The distribution range of Proctoporus is discontinuous, with many places lacking herpetological surveys. Here, based on morphological data, we describe a new species of Proctoporus from a remote location on a mountaintop north of the Cordillera de Vilcabamba in southeastern Peru. The new species is readily distinguished from all other species of Proctoporus by the presence of three anterior infralabials, three rows of pregular scales and the absence of enlarged pregular scales. With this new species, the species diversity has increased to 19 since 18 species have previously been identified. Copyright
