Aphantophryne is a genus of microhylid frogs found in New Guinea and in Mindanao, the Philippines. Originally described by Fry in 1917, Richard G. Zweifel considered in 1956 Aphantophryne synonymous to Cophixalus. The genus was resurrected in 1989 to house two new species in addition to the type species, A. pansa. A molecular study on the subfamily Asterophryinae in 2017 revealed that two species originally included in the genus Oreophryne were more closely related to Aphantophryne than to other Oreophryne, and were consequently moved to this genus. The study also revealed a number of undescribed species.
Nyctimystes fluviatilis, also known as the Indonesian big-eyed tree frog, is a species of frog in the subfamily Pelodryadinae of the family Hylidae. It is endemic to New Guinea and is known from Idenburg River and Wapoga River in Papua province, Indonesia, and from the Torricelli Mountains in the East Sepik Province and Kavorabip in the Western Province, both in the western Papua New Guinea.
Choerophryne darlingtoni is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and found in the New Guinea Highlands. The specific name darlingtoni honors P. Jackson Darlington Jr., an American evolutionary biologist and zoogeographer. Common name Darlington's rainforest frog has been coined for it.
Choerophryne siegfriedi is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from its type locality, Mount Elimbari in the Simbu Province.
Aphantophryne minuta is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from its type locality near Myola Guest House in the Owen Stanley Range, Northern Province, from another locality in the same province, Mount Tafa; only a single specimen is known from each locality. The specific name minuta refers to the very small size of this species. Common name Myola Guinea frog has been coined for it.
Austrochaperina adamantina is a species of frog in the family Microhylidae. It is endemic to New Guinea and occurs in the Torricelli and Bewani Mountains in the West Sepik Province, Papua New Guinea. The specific name adamantina is Latin for "like a diamond" and refers to Jared Diamond, credited as the collector of the holotype and "great many other valuable herpetological specimens from Papua New Guinea".
Austrochaperina kosarek is a species of frog in the family Microhylidae. It is endemic to New Guinea and only known from its type locality, Kosarek, in West Papua (Indonesia). It is only known from one specimen collected in 1979. It has not been well-studied but it might be widespread in suitable habitat.
Barygenys exsul is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea. It is known from Rossel and Sudest Islands in the Louisiade Archipelago, east of New Guinea. It is uncertain whether the specimens from Sudest really are conspecific with this species. Barygenys apodasta and Barygenys resima were mixed with this species prior to their description in 2013.
Cophixalus nubicola is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and only known from its type locality, Mount Michael in the Eastern Highlands Province. The specific name nubicola refers to its cloud-swept habitat. Common name Michael rainforest frog has been coined for this species.
Cophixalus parkeri is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea where it occurs in the central mountainous region between Chimbu and Morobe Provinces. The specific name parkeri presumably honours Hampton Wildman Parker, an English zoologist and herpetologist to whose perusal Arthur Loveridge sent the holotype. Common name Papua rainforest frog has been coined for it.
Cophixalus pipilans is a species of frog in the family Microhylidae. It is endemic to northern mainland Papua New Guinea and occurs between Lae and the Adelbert Mountains. The specific name pipilans is derived from the Latin verb pipilio and means "peeping". Common name Sempi rainforest frog has been coined for this species.
Cophixalus riparius is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and occurs in the New Guinea Highlands in Madang, Southern Highlands, and Western Highlands provinces southeastward to the Morobe Province. The specific name riparius refers to the creek-side habitat from which many specimens in the type series were collected. Common name Wilhelm rainforest frog has been coined for this species.
Cophixalus tagulensis is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and only known from the Tagula Island in the Louisiade Archipelago, east of New Guinea. It is only known from the type series of three specimens collected in 1956.
Cophixalus verecundus is a species of frog in the family Microhylidae. It is endemic to New Guinea in Papua New Guinea, where it is only known around Mt. Bellamy in Owen Stanley Mountains though it may more widely distributed.
Sphenophryne thomsoni, sometimes known as Thomson's toothless frog, is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and occurs in the southeastern peninsular New Guinea, Louisiade Archipelago, d'Entrecasteaux Islands, and Woodlark Island. It was formerly in its own monotypic genus Genyophryne. The specific name thomsoni honours Basil Thomson, a British intelligence officer, police officer, prison governor, colonial administrator, and writer.
Oreophryne biroi is a species of frog in the family Microhylidae. It is endemic to New Guinea and occurs on the north coast from Madang Province in Papua New Guinea to the Cyclops Mountains in Papua province, Western New Guinea (Indonesia). The specific name biroi honours Lajos Bíró, a Hungarian zoologist and ethnographer who collected the holotype. Common name New Guinea cross frog has been coined for it.
Oreophryne notata is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and known from two localities, Ialibu, its type locality in the Southern Highlands Province, and Tabubil in the Western Province. It might occur more widely. The specific name notata is from Latin nota meaning a "mark" or "letter" and refers to the diagnostic U-like pattern on the lores.
Oreophryne wolterstorffi is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and only known from a single specimen collected from "Deutsch-Neu-Guinea", in what now is Madang Province. Common name Wolterstorff's cross frog has been coined for it.
Sphenophryne cornuta is a species of frogs in the family Microhylidae. It is endemic to New Guinea where it is widespread and found both in the Western New Guinea (Indonesia) and Papua New Guinea. Common name horned land frog has been proposed for it.
Cornufer gilliardi, commonly known as Gilliard's wrinkled ground frog, is a species of frog in the family Ceratobatrachidae. It is endemic to the Whiteman Ranges of New Britain, Bismarck Archipelago. The specific name gilliardi honors Ernest Thomas Gilliard, an American ornithologist who, together with Margaret Gilliard, collected the holotype.
