I think you mean genera and subfamily. Clown treefrogs are of the genus Dendropsophus and red-eyes, Agalychnis. On top of that, the clown is of the subfamily Hylinae, the red-eye, Phyllomedusinae. There order would be Anura, tailless amphibians, AKA frogs & toads. Their suborder is Neobatrachia or advanced frog.
