Summary

Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic.

Taxonomy and systematics

The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States.

The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae, Phyllomedusidae and Pelodryadinae.

The following genera are recognised in the family Hylidae:
