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.
Leptobrachella is a genus of frogs in the family Megophryidae. Members of Leptobrachella are found throughout Asia including on Borneo and the Natuna Islands. They are sometimes referred to as Borneo frogs, slender-armed frogs, or dwarf litter frogs. The genus contains over 82 species with 25 found in China alone.
The Microhylinae are a subfamily of microhylid frogs. It contains 9 genera. Phylogenetic studies have estimated the family Microhylidae to be about 52 million years old.
Theloderma, the bug-eyed frogs, mossy frogs or warty frogs, is a genus of frogs in the family Rhacophoridae, subfamily Rhacophorinae. They are found from northeastern India and southern China, through Southeast Asia, to the Greater Sunda Islands; the highest species richness is in Indochina. Some species, especially T. corticale, are sometimes kept in captivity.
Rhacophorus is a genus of frogs in the shrub-frog family Rhacophoridae, which, with the related Hylidae, is one of the two genera of true tree frogs. They are found in China, India, Japan, and throughout Southeast Asia, including the island of Borneo. Over 40 species are currently recognised.
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,.
Leptolalax is a genus of frogs in the family Megophryidae. They are sometimes known as Asian toads, metacarpal-tubercled toads, or slender litter frogs, although many species-specific common names do not follow these conventions, and many species do not have common names. They are widely distributed in southeastern and eastern Asia, from southern China and northeastern India to the Malay Peninsula and Borneo. Leptolalax are typically small and have a cryptic colour pattern and no obvious morphological characters useful in systematic studies. Consequently, both molecular genetic analyses and analysis of advertisement calls by male frogs have been important in identifying new species.
Xenophrys is a genus of amphibians in the family Megophryidae. They are found in southeastern Asia to Borneo. Their common name is strange-horned toads.
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.
Rhacophorus robertingeri is a species of frogs in the family Rhacophoridae endemic to Vietnam. First found in the Annamite Mountains of Vietnam, it is now known from mountain areas between Hà Giang or Nghệ An Province in the north and Gia Lai or Bình Thuận Province in the south, depending on the source. This species can be differentiated from its congeners based on the pointed projection at the tibiotarsal articulation, as well as coloration.
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).
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.
Theloderma vietnamense, the South Vietnamese bug-eyed frog or South Vietnamese bug eye frog, is a frog in the family Rhacophoridae. It is endemic to Vietnam, Cambodia, and Laos. It has been observed no higher than 1400 meters above sea level.
