Genus Pternohyla is a group of arboreal frogs commonly found in Central America. There are several synonyms for this genus, including Agalychnis, Hyla, and Litoria. Agalychnis derives from the Greek words "agal" meaning bright and "ichne" meaning foot, possibly referencing the colorful markings on their feet. Hyla is a more general name for tree frogs and was previously used for species now classified under Pternohyla. Litoria is a name used for tree frogs in Australia, possibly due to similarities in their arboreal lifestyle. Despite the different names, all species in this genus share similar physical characteristics and habitats.
