Ranoidea is a genus of frogs in the subfamily Pelodryadinae. They are found in Australia, New Guinea, and two nearby groups of islands: Maluku Islands (=Moluccas) and Louisiade Archipelago;[1] the circumscription of this taxon is still controversial.

Ranoidea novaehollandiae is the type species of the genus Cyclorana which—pending further studies—may become recognized again.[2]

Taxonomy[edit]

Species in this genus were until recently placed in the then-paraphyletic genus Litoria (and mostly still are in Wikipedia); many of them had been placed in even larger Hyla before. However, in 2016 Duellman and colleagues split Litoria into several genera;[1][2] the species now in Ranoidea were placed in the genus Dryopsophus. However, the oldest available name for these species is Ranoidea;[1] these changes are not yet widely recognized, and the AmphibiaWeb continues to recognize Litoria in the older, broad sense.[3] The AmphibiaWeb also recognizes Cyclorana,[3] a position that, without additional amendments, renders Ranoidea paraphyletic; it may be treated as a subgenus.[1]

Some controversy also surrounds whether the subfamily Pelodryadinae is part of the family Pelodryadidae, as suggested by Duellman and colleagues[2] and recognized in the Amphibian Species of the World,[1] or part of the family Hylidae, as recognized in the AmphibiaWeb.[3]

Description and ecology[edit]

The pupil is horizontally elliptical, and the palpebral membrane is unpigmented. Many species have tadpoles that develop in mountain streams and have enlarged ventral mouths.[2] However, "Cyclorana" are adapted to standing and often temporary bodies of water.[4]

Species[edit]

There are 75 species in this genus:[1]
