The Genera of Phyllomedusine Frogs (Anura: Hylidae)

This volume presents a thorough overview of a strikingly distinct lineage of Neotropical tree frogs, known for their vertical pupils and the habit of laying eggs on leaves suspended above water. The author draws attention to their unique chromosomal count and the powerful skin peptides that set them apart from other hylids. Readers are introduced to the broad geographic sweep of these amphibians, ranging from northern Argentina to southern Mexico, including the island of Trinidad.

Through careful examination of morphology, cytogenetics, and behavior, the work sorts the group into three recognized genera, offering detailed descriptions of features such as webbing, disc size, and glandular patterns. A newly proposed genus, Pachymedusa, is defined alongside the better‑known Agalychnis, highlighting subtle yet significant differences among species. The systematic framework is built on both field observations and a synthesis of earlier literature, providing a clear roadmap for identification.

For students, researchers, and nature enthusiasts alike, this guide supplies concise keys, range maps, and taxonomic remarks that illuminate the evolutionary story of these leaf‑dwelling frogs. It balances technical depth with accessible language, making it a valuable reference for anyone curious about the diversity hidden in tropical rainforests.
