Species in this genus were until recently placed in the then-
paraphyletic genus
Litoria; many of them had been placed in even larger
Hyla before. In 2006, Frost and colleague synonymised
Nyctimystes with
Litoria to make a monophyletic
Litoria within a monotypic
Pelodryadinae. Later, in 2016, Duellman and colleagues restored
Nyctimystes and moved some of the remaining
Litoria species to the resurrected genus
Dryopsophus. ==Description and ecology==
