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.
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.
Anodonthyla is a genus of microhylid frogs endemic to Madagascar. Molecular data suggest that it is the sister taxon to all other species in the subfamily Cophylinae.
Stumpffia is a genus of microhylid frogs that are endemic to Madagascar. They are mostly brown frogs that typically live among leaf litter. S. contumelia has a snout–vent length of about 8–9 mm (0.31–0.35 in), making it one of the world's smallest frogs, and several others in the genus are only slightly larger. The largest species is no more than 28 mm (1.1 in).
Asterophryinae is a subfamily of microhylid frogs distributed in an area from the Peninsular Malaysia through the Malay Archipelago to northern Australia.
Kalophrynus is a genus of microhylid frogs. It is the only genus in the subfamily Kalophryninae. The species in this genus are found in southern China, in Southeast Asia to Java and Philippines, and in Assam, India.
Microhyla, commonly known as the rice frogs or narrow-mouthed frogs, is a genus of frogs in the family Microhylidae. It consists of 42 species of diminutive frogs. Members of this genus are widespread from Ryukyu Is. in Japan, and throughout South-east Asia,.
Nanohyla annamensis, commonly known as the Annam chorus frog, Annam narrow-mouthed frog, Vietnam rice frog or minute narrow-mouthed frog, is a species of frog in the family Microhylidae. It is found in Cambodia, Laos, Thailand, and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, swamps, and intermittent freshwater marshes. It is listed as vulnerable by the IUCN Red List due to habitat loss and degradation.
Nanohyla annectens, the Larut Hills rice frog, is a species of frog in the family Microhylidae. It is found in Peninsular Malaysia; records from Thailand and elsewhere probably refer to other species. Its natural habitats are evergreen submontane and montane rainforests. It lives on the forest floor and in puddles and breeds in temporary pools. It is locally threatened by habitat loss.
Micryletta erythropoda, commonly known as the Mada paddy frog, is a species of frog in the family Microhylidae. It is known from Myanmar, Thailand, and Vietnam. Its natural habitats are swamps, freshwater marshes, and intermittent freshwater marshes. While formerly classified in the genus Microhyla, a 2018 study found it to belong to the genus Micryletta instead. A study performed in 2019 found that several Micryletta populations in southern Myanmar and Thailand that were formerly assigned to M. inornata actually belong to M. erythropoda; prior to this, M. erythropoda was considered endemic to Vietnam.
Nanohyla marmorata is a species of frog in the family Microhylidae. It is found in Laos and Vietnam. It is not considered threatened by the IUCN.
Nanohyla nanapollexa is a species of frog in the family Microhylidae. It is also known as the no-thumb pigmy frog and three-fingered pigmy narrow-mouth frog. It is endemic to Vietnam and is known from Quang Nam and Phu Yen Provinces.
Nanohyla perparva is a diminutive species of frog in the family Microhylidae. It is endemic to Borneo and found in Kalimantan (Indonesia), Brunei, and Sabah and Sarawak (Malaysia). The nominal species includes distinct lineages that likely represent different species. Common names least narrow-mouthed frog and Labang forest rice frog have been proposed for this species.
Nanohyla petrigena is a species of frog in the family Microhylidae. It is found in northern and central Borneo and in the Sulu Archipelago of the Philippines. The common names pothole narrow-mouthed frog and Kapit rice frog have been coined for the species.
Rhombophryne is a genus of microhylid frogs endemic to Madagascar. It is currently estimated to include more than 23 species, but only 20 of these are currently described. The common name 'diamond frog' has been proposed and used for members of this genus.
Rhombophryne serratopalpebrosa is a species of frog of the Madagascar endemic microhylid subfamily Cophylinae. Genetic evidence revealed that it is a species complex, in need of resolution. This work has made significant progress, and five related species have been described from this complex between 2014 and 2017. It is threatened by habitat loss.
Andolalao Rakotoarison is a Malagasy herpetologist.
Nanohyla is a genus of frogs in the family Microhylidae. Members of the genus are known as pygmy narrow-mouthed frogs. The members of the genus are found throughout Southeast Asia in the countries of Vietnam, Laos, Cambodia, Thailand, Malaysia, Brunei, Indonesia and the Philippines.
Nanohyla hongiaoensis is a species of frog in the family Microhylidae. It is also known as the Hongiao narrow-mouth frog. It is only known from Bidoup Nui Ba National Park in Lam Dong Province, Vietnam. Little is known about the species or its distribution and so it is likely to be rated data deficient by the IUCN Red List.
Mini scule is a species of microhylid frog endemic to Madagascar that was described in 2019. The scientific name of the species refers to its size, being a pun on the word miniscule. It is very small, measuring only 8.4 to 10.8 mm in snout–vent length. It has bronze underparts with a brown groin and back of the thigh, cream upperparts with brown flecking, a dark brown side of the head, and a red iris. It is known only from the Sainte Luce Reserve, where it inhabits areas with deep leaf litter near semi-permanent water bodies. Specimens of frogs from Mandena, the Vohimena mountains, the southern Anosy Mountains, and Tsitongambarika may also be of this species. Like other species in the genus Mini, it received media attention when first described due to the wordplay in its scientific name.
