The Bayesian phylogenetic tree of selected South American Pristimantis; for taxon sampling design, see Material and Methods. Nodes with less than 50% of the post burn-in tree samples were collapsed. Posterior probability values (pp) given only for main lineages. The new species, P. sinschi sp. nov., is a member of a monophyletic clade, yet unnamed species Group, comprising species from Peruvian Cordillera Oriental – P. lindae and P. rhabdocnemus. The PPPF representatives of P. danae species Group form two distinct genetic lineages, one conspecific with P. albertus and the second closer to P. stictogaster (labelled as P. cf. stictogaster). Species-group names follow Padial et al. (2014). DNA sequences (for 12S rRNA and 16S rRNA) of taxa retrieved from GenBank are labelled by standard GenBank accession numbers (in cases where both 16S rRNA and 12S rRNA for the same specimen are under different accession numbers, taxon is labelled with 16S rRNA number), all other codes stand for our new material.
