The Genera of Phyllomedusine Frogs (Anura: Hylidae)

The work examines a distinct Neotropical lineage of hylid frogs, arguing for recognition as a phyllomedusine subfamily and presenting diagnostic characters including a vertical pupil, a haploid chromosome number of 13, distinctive skin peptides, and reproductive behavior of depositing egg masses on vegetation above water while tadpoles possess a sinistral ventral spiracle. It outlines the group's low- to mid-elevation distribution in Central and South America, revises generic boundaries, and supplies genus-level definitions and species inventories for Agalychnis, a monotypic Pachymedusa, and a broadly circumscribed Phyllomedusa, with comparative notes on skull, limb, and integumentary morphology.
