This article describes six new species of the genus Pristimantis from Amazonian cloud forests in Ecuador and presents a phylogeny showing their relationships. Additionally, the osteology of two new species is described using high-resolution x-ray computed tomography.
We describe six new species of rainfrogs of the genus Pristimantis (Strabomantidae) from Amazonian cloud forests in Ecuador. We also present a phylogeny showing the relationships of the new species. The phylogeny is based on mitochondrial genes 16S rRNA (16S), 12 rRNA (12S), NADH-ubiquinone oxidoreductase chain 1 (ND1) and the nuclear gene recombination-activating 1 (RAG1). We also describe the osteology of two of the new species using high-resolution x-ray computed tomography. The new species belong to two clades. The first clade is sister to the subgenus Huicundomantis and includes P. tamia sp. nov., P. miktos, and P. mallii. Pristimantis tamia sp. nov. is morphologically similar to P. miktos, P. mallii, P. martiae, and P. incomptus, but differs from them by lacking vocal slits and tympanic membrane and by having light greenish blue iris. Based in our results we expand the subgenus Huicundomantis to include the P. miktos species group. The second clade is remarkable by being highly divergent and consisting exclusively of new species: P. anaiae sp. nov., P. glendae sp. nov., P. kunam sp. nov., P. resistencia sp. nov., and P. venegasi sp. nov. The new species resemble P. roni, P. yanezi, P. llanganati, P. katoptroides, P. verecundus, and P. mutabilis but can be distinguished from them by lacking vocal slits and tympanic membrane and by having large dark round areas with thin clear borders in the sacral region. All six new species occur in the eastern slopes of the Ecuadorian Andes and are known from a single locality in Llanganates or Sangay National Park. We recommend assigning all of them to the Data Deficient (DD) Red List category. Based in our high-resolution x-ray tomographies, we report the presence of structures that appear to be intercalary elements. This would be the first report of such structures in Terrarana.
