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.
The glass frogs belong to the amphibian family Centrolenidae. While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent, giving the glass frog its common name. The internal viscera, including the heart, liver, and gastrointestinal tract, are visible through the skin. When active their blood makes them visible; when sleeping most of the blood is concealed in the liver, hiding them. Glass frogs are arboreal, living mainly in trees, and only come out for mating season. Their transparency conceals them very effectively when sleeping on a green leaf, as they habitually do.
The Tukeit Hill frogs are three species of frog in the genus Allophryne. Originally erected for the species Allophryne ruthveni, the genus was placed as the only member of the subfamily Allophryninae, which was in turn placed in the family Centrolenidae, but they are now considered as the only genus in the monotypic family Allophrynidae.
Cophylinae is a subfamily of microhylid frogs endemic to Madagascar. It has over 100 species in eight genera. Members of this subfamily range from minute to fairly large, and they are highly ecologically diverse. DNA barcode research has revealed a significant taxonomic gap in this subfamily, and an estimated 70+ candidate species were identified. Many of these have subsequently been described, as well as numerous new discoveries.
Asterophryinae is a subfamily of microhylid frogs distributed in an area from the Peninsular Malaysia through the Malay Archipelago to northern Australia.
Mantellinae is a subfamily of frogs in the family Mantellidae. These frogs are native to Madagascar and Mayotte. The species vary in size from under 25 mm to over 100 mm. The subfamily is most famous for the genus Mantella, which contains species that superficially resemble poison dart frogs of the tropical Americas, and have converged on similar aposematic colouration and toxins. As of 2 May 2016, there are 128 described species in this subfamily, but several more are described each year.
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.
Limnonectes is a genus of fork-tongued frogs of about 75 known species, but new ones are still being described occasionally. They are collectively known as fanged frogs because they tend to have unusually large teeth, which are small or absent in other frogs.
Callulops boettgeri, also known as Boettger's Callulops frog, is a species of frog in the family Microhylidae. It is endemic to Halmahera in the Maluku Islands of Indonesia. It is only known from the holotype collected from Galela in 1894. The genus-level placement of this little known frog has changed many times, and it is still unclear whether it should be placed in some other genus.
Platymantis spelaeus, also known as the Negros cave frog or cave wrinkled ground frog, is a species of frog in the family Ceratobatrachidae. It is endemic to the Philippines, where it is only found in the forested limestone areas of southern Negros. It is one of the two cave-dwelling Platymantis species, the other one being Platymantis insulatus.
Microhyla mantheyi is a species of microhylid frog. It is endemic to the Malay Peninsula and occurs in southern Myanmar, southern Thailand, Peninsular Malaysia, and Singapore. However, molecular data suggest that the nominal species consists of at least two cryptic species.
Robert Frederick Inger was an American herpetologist. During his lifetime, he wrote numerous books and publications about herpetology. He was also the curator for amphibians and reptiles at the Field Museum in Chicago, Illinois.
Liurana is a genus of frogs in the family Ceratobatrachidae. It is the only genus in the subfamily Liuraninae.
Vietnamophryne is a divergent genus of Asterophryinae frogs found in Indochina. Its closest relative is the genus Siamophryne. The genus Vietnamophryne was first described by Poyarkov, et al. (2018).
Vietnamophryne inexpectata is a species of microhylid frog endemic to the Central Highlands of Vietnam. Its type locality is Kon Chu Rang Nature Reserve, Gia Lai Province, central Vietnam.
Vietnamophryne orlovi is a species of microhylid frog endemic to northern Vietnam. Its type locality is Phia Oac-Phia Den National Park, Cao Bang Province, northern Vietnam.
Vietnamophryne occidentalis is a species of microhylid frog endemic to northern Thailand. Its type locality is Doi Tung Mountain, Chiang Rai Province, northern Thailand.
Raorchestes cangyuanensis is a species of frog in the family Rhacophoridae. It is known from its type locality in the eponymous Cangyuan County in southwest Yunnan, China, as well as from Mizoram in northeastern India and Satchari National Park in Bangladesh; its range presumably includes the intervening Myanmar.
The Tenasserim spadefoot toad is a species of toad from the Leptobrachium genus. The species is endemic to western Thailand and was scientifically described in 2018.
