Descriptions of New Hylid Frogs From Mexico and Central America by William Edward Duellman is a taxonomic paper that introduces and describes new species of hylid frogs (tree frogs) from Mexico and Central America. In this study, Duellman expands the scientific knowledge of the Hylidae family, which is known for its wide distribution across tropical and subtropical regions of the Americas.The work begins by explaining the significance of the Hylidae family in amphibian taxonomy, highlighting their diverse forms, behaviors, and ecological adaptations. These frogs are typically arboreal, living in trees, but some species are found in terrestrial or semi-aquatic environments. Duellman’s study focuses on species that had not been formally described in scientific literature up to that point.
