A Review of the Middle American Tree Frogs of the Genus Ptychohyla

Hidden among the mist‑clad slopes of Central America’s cloud forests are the shy tree frogs of the genus Ptychohyla. Their lives unfold beside roaring mountain streams, where they cling to leaves and call into the night, yet they have long eluded scientists. This work opens a window onto that secret world, explaining why these amphibians have remained so poorly known despite decades of exploration in the region’s lowlands.

Drawing on years of painstaking field trips across southern Mexico, Guatemala, and El Salvador, the author assembled the most comprehensive collection of specimens, tadpoles, and recorded breeding calls ever gathered for the group. The study weaves detailed descriptions, vivid illustrations, and careful analysis of their anatomy and behavior, offering listeners a clear picture of each known species and the challenges that still surround their classification. It’s an invitation to explore a delicate ecosystem through the eyes—and sounds—of its most elusive inhabitants.
