Guide to the frogs of the Iquitos Region, Anfibios del Ecuador. Mus. Dipsas gracilis and D. viguieri are not distinguishable by any reported characteristics of the taxa. The type locality of D. oreas and many other South American amphibians and reptiles obtained by the naturalist James Orton is the “elevated Valley of Quito,” which has been erroneously interpreted narrowly as the vicinity of Quito, Ecuador. These species are not clearly distinguishable on the basis of characters discussed in the literature, and the assignment of these names to specimens from eastern Ecuador needs to be reviewed in conjunction with study of their holotypes. The new phylogeny differs significantly from all previous morphology-based hypotheses of relationships, and shows that hypotheses based on few traits are likely to misrepresent evolutionary history.
