Dryophytes

Dryophytes consists of small tree-dwelling frogs, usually green or gray in color. They have digits ending with expanded discs which help them to stick to surfaces like trees.^[1][2]

Tree frogs of the genus Dryophytes are found in wetlands throughout their range, as well as in temperate forests both on the ground and in trees.^[3]

The genus Dryophytes was first described by Fitzinger in 1843.^[4] Later it was placed into the genus Hyla, the true tree frogs, by Boulenger in 1882.^[4] Fouquette and Dubois 2014, treated Dryophytes as a subgenus of Hyla.^[4] Dryophytes was finally resurrected as an independent genus by Duellman et al. in 2016.^[1][4][5][6]

Only geographical, rather than morphological, differences separate Dryophytes from the genus Hyla. Hyla is found only in the Old World, whereas Dryophytes is distributed in the New World and Asia. Most members occur in North America, but five species are found in eastern temperate Asia; D. flaviventris, D. immaculatus, D. japonicus, D. leopardus, and D. suweonensis.^[1][7]

The genus Dryophytes contains 21 species.^[1][3]
