The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 57 genera and 11 subfamilies.
Nyctimystes is a genus of tree frogs in the subfamily Pelodryadinae of the family Hylidae. They are principally Papuan species, but also inhabit islands in the Moluccas. All species in this genus have one distinct feature that separates them from other species in the family, the lower eyelid is marked with pattern of lines, veins, or dots. This feature presumably acts as camouflage when the frogs are at rest during the day.
Asterophryinae is a subfamily of microhylid frogs distributed in an area from the Peninsular Malaysia through the Malay Archipelago to northern Australia.
Barygenys is a genus of microhylid frogs. They are endemic to New Guinea and the adjacent Louisiade Archipelago. So far only known from Papua New Guinea, the range of the genus is expected to reach Papua province in the Indonesian part of New Guinea. Despite not being known from Papua, common name Papua frogs has been suggested for them.
Hylophorbus is a genus of microhylid frogs endemic to New Guinea. Common name Mawatta frogs has been coined for them.
Austrochaperina is a genus of microhylid frogs found on New Guinea, New Britain and Australia.
Choerophryne is a genus of microhylid frogs, commonly known as Torricelli mountain frogs, endemic to New Guinea. These frogs are small, with the body length measured from snout to vent between 11 and 23 mm.
Copiula is a genus of microhylid frogs endemic to New Guinea. The common name Mehely frogs has been coined for them. They are leaf-litter inhabitants.
Oreophryne, the cross frogs, is a genus of microhylid frogs endemic to Southern Philippine, Celebes and the Lesser Sunda Islands, and New Guinea.
Platymantis is a genus of frogs in the family Ceratobatrachidae. They are commonly known as wrinkled ground frogs, ground frogs, and forest frogs.
Choerophryne brunhildae is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from the Adelbert Range, the Bewani Mountains, and the Hunstein Mountains.
Xenorhina bidens is a species of frog in the family Microhylidae. It is endemic to New Guinea and found between Lorentz River in the west and Fly River in the east, thus being present in both West Papua (Indonesia) and Papua New Guinea. Common name Digul River fanged frog has been coined for it, in reference to Digul River where the type series was collected in 1904 or 1905.
Xenorhina zweifeli is a species of frog in the family Microhylidae. It is endemic to New Guinea and is only known from the Bewani and Hunstein Mountains in northern Papua New Guinea. The species is named for American herpetologist Richard G. Zweifel, a specialist in New Guinean herpetology and microhylid frogs; he is also said to share "characteristically terse vocalizations" with this frog.
Papurana is a genus of frogs in the family Ranidae, "true frogs". They are known from Southeast Asia, New Guinea, and northern Australia. Papurana daemeli is the only ranid frog found in Australia.
Stegonotus is a genus of snakes in the family Colubridae. Species of the genus Stegonotus are native to Australia, Indonesia, and New Guinea.
Cornufer is a genus of frogs in the family Ceratobatrachidae. It has been greatly expanded by Brown, et al. (2015) to include most Australasian frogs in the family Ceratobatrachidae. Species are found in Melanesia and Polynesia — in Palau, Fiji, New Guinea, and in the Admiralty, Bismarck, and Solomon Islands.
Ranoidea is a genus of frogs in the subfamily Pelodryadinae. They are found in Australia, New Guinea, and two nearby groups of islands: the Maluku Islands, and the Louisiade Archipelago. The circumscription of this taxon is still controversial.
Sphenophryne is a genus of frogs in the family Microhylidae from New Guinea. It reached its current composition in 2017 when Rivera and colleagues brought the genera Genyophryne, Liophryne, and Oxydactyla into synonymy of the then-monotypic Sphenophryne. However, the AmphibiaWeb continues to recognize these genera as valid.
Litoria amnicola, the Raja Ampat torrent tree frog, is a frog in the family Hylidae, endemic to Indonesia. It has been found on Salawati Island, which is in the Raja Ampat archipelago.
