A Review of the Frogs of the Hyla bistincta Group

"A Review of the Frogs of the Hyla bistincta Group" by William Edward Duellman is a scientific publication crafted during the early 1960s. This work primarily focuses on the classification and characteristics of a group of frogs within the genus Hyla, specifically the Hyla bistincta group, which includes several species found in the mountainous regions of Middle America. The book combines extensive field research and morphological analysis to provide an in-depth examination of these amphibians. In this review, Duellman presents detailed accounts of five species within the Hyla bistincta group, including their distinctive morphological traits, habitats, and breeding behaviors. Each species is assessed systematically, featuring descriptions of their physical characteristics and behaviors, such as coloration patterns and calling abilities. The work highlights the evolutionary relationships among these frogs, noting adaptations for aquatic life and emphasizing the ecological contexts in which they thrive. By examining specimens from various collections and providing comparative data, Duellman contributes significantly to the understanding of these hylid frogs and their classification within the broader amphibian family.
