A Synopsis of Neotropical Hylid Frogs, Genus Osteocephalus

"A Synopsis of Neotropical Hylid Frogs, Genus Osteocephalus" by Linda Trueb and William E. Duellman is a scientific publication written in the early 1970s. The work presents a detailed taxonomic review of the genus Osteocephalus, focusing particularly on the various species of hylid frogs found throughout the Neotropical regions, notably in the Amazon Basin and bordering Andean slopes. This publication aims to clarify species identification and taxonomy within this genus, addressing previous confusions and misidentifications. The opening of the synopsis discusses the initial challenges faced by the authors during their research in Amazonian Ecuador, where they encountered numerous unidentified frog specimens. Their studies led to the recognition of five distinct species within the genus Osteocephalus, which they detail with observations on morphology, distribution, and taxonomic revisions. The authors emphasize their reliance on both museum specimens and live observations, while also noting certain gaps in the available data that may require further research. Overall, the beginning sets the stage for an in-depth, scientific exploration of hylid frogs that highlights the complexity and diversity of this specific group of amphibians.
