Larvae, Literature-review, Flattened-Waterfall-Frog, Semiterrestrial, Terminology


A literature survey for the external morphology of tadpoles for species in the genus Cycloramphus Tschudi, 1838, which is mainly represented by larval descriptions, resulted in finding some inconsistent character descriptions. In a few cases, some of the information is either not presented or mistakenly reported; in some cases, the illustrations provided the information not present in the descriptions. Here in we use a sample of tadpoles of an insular population identified as Cycloramphus boraceiensis, present a description for it, compare it to the original larval description for this species, and using it as a model, present a comparative review of the other larval descriptions for Cycloramphus tadpoles. We evaluate that most of the mistakes we found in the literature are associated to the unique morphology of these semiterrestrial larvae and some of their seemingly adaptation to their microhabitats, which for the majority of the known species is a film of water running associated to or near streams.
