We describe two new species of poison frog from central and southern Peru that have been referred to as Ameerega picta, A. hahneli, or A. altamazonica throughout the past thirty years. Our phylogenies generated with genomic data provide strong support that the two new species are successive sisters to two described taxa, A. rubriventris and A. altamazonica, and collectively comprise the Ameerega rubriventris complex. The first new taxon, Ameerega panguana sp. nov., can be distinguished from all other Ameerega by its combination of a unique white venter and an advertisement call of 1\–2 notes per second. The second new taxon, Ameerega imasmari sp. nov., is the only cryptically colored Ameerega species that is disttributed across the Fitzcarrald Arch in Southern Peru which possesses a \‘peep\’ advertisement call consisting of 3\–4 notes per second and a dominant frequency of 4.3\–4.5 kHz. Within the Ameerega rubriventris complex, we observed differences between species in their ventral coloration, tympanum diameter, and call, which suggest that these taxa are reproductively isolated from each other.

We used an integrative taxonomy approach to investigate the taxonomic identity of several populations of glassfrogs from Peru, which are notoriously challenging to identify due to their overall similarity in morphology and coloration. We relied on comparisons of morphology, bioacoustics, and partial fragments of 16S rRNA DNA sequences. We report for the first time the presence of Hyalinobatrachium mondolfii in Peru, being this the southernmost locality known for the species. Likewise, we update and extend the distribution ranges of Rulyrana spiculata and Cochranella nola in the Andes of Peru, provide a 16S sequence of a topotype of R. spiculata, and confirm its presence in Bolivia. For all three species, we increase the current knowledge on their geographic distribution and genetic and phenotypic variation.
