True frogs is the common name for the frog family Ranidae. They have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa, and Asia. The Asian range extends across the East Indies to New Guinea and a single species, the Australian wood frog, has spread into the far north of Australia.
Amolops is a genus of true frogs native mainly to eastern and south-eastern Asia. These frogs are closely related to such genera as Huia, Meristogenys, Odorrana, Pelophylax and Rana, but still form a distinct lineage among the core radiation of true frogs. They are commonly known as "torrent frogs" after their favorite habitat - small rapid-flowing mountain and hill streams - but this name is used for many similar-looking frogs regardless of whether they are loosely related.
Amolops formosus, also known as Assam sucker frog, beautiful stream frog, Assam cascade frog, or hill stream frog, is a species of frog found in high gradient streams of northern India, northern Bangladesh, and Nepal, possibly also Bhutan, although these records may represent confusion between Amolops himalayanus and this species; the latest available IUCN assessment from 2004 treats A. himalayanus as a synonym of A. formosus.
Amolops monticola is a species of frog in the family Ranidae, the "true frogs". It is found in the Northeast India, eastern Nepal, and western China, although there is some uncertainty regarding the Chinese records. It probably also occurs in the intervening Bhutan. Common names mountain sucker frog, mountain stream frog, mountain torrent frog, and mountain cascade frog have been coined for it.
Amolops cremnobatus is a species of frogs in the family Ranidae. It is found in north-central Laos and Vietnam. Its range might extend into Thailand. The specific name cremnobatus is derived from Greek kremnobates, meaning "frequenter of steep places", and refers to the steep waterfall from which the type series were collected. Common name Lao sucker frog has been coined for it.
Amolops nepalicus is a species of frog in the family Ranidae. It is endemic to Nepal and is only known from two localities in the Sankhuwasabha District. Common names Nepal sucker frog and Nepal cascade frog have been proposed for it.
Amolops ricketti is a species of frog in the family Ranidae that is found in southern and eastern China and northern and central montane Vietnam.
Amolops tuberodepressus is a species of frog in the family Ranidae. It is endemic to Yunnan, China and known from Wuliang and Ailao Mountains in Jingdong County. Once suspected to be synonym of Amolops mantzorum, its validity was confirmed with molecular methods in 2014.
The Doichang frog is a species of frog in the family Dicroglossidae. It is only known from its type locality, Doi Chang, mountain north of Chiang Mai (Thailand), Fansipan mountain in northern Vietnam, and Huanglianshan National Nature Reserve in Yunnan, China.
The Tonkin frog is a species of frogs in the family Ranidae. It is found in northern Vietnam and in adjacent southern China. The specific name is derived from Bac Bo, the Vietnamese name for northern Vietnam, as the species was first described from there.
Amolops daorum is a species of frog in the family Ranidae. It is known from its type locality in the vicinity of Sa Pa in northern Vietnam near the Chinese border, Hong Kong, and Houaphanh Province in eastern Laos; presumably it also occurs the intervening areas. The Hong Kong record is considered suspicious, however.
The common green frog is a frog species of in the true frog family Ranidae; some sources still use the old name Rana erythraea. It lives in Southeast Asia and is also known as green paddy frog, red-eared frog or leaf frog. The last name, however, commonly refers to the Neotropical tree frogs which make up the subfamily Phyllomedusinae. These are not closely related to H. erythraea, belonging to family Hylidae instead.
Odorrana jingdongensis is a species of frogs in the family Ranidae. It is known from southern China and northern Vietnam, though it quite likely also occurs in the adjacent areas in Laos and in Myanmar. Its name refers to its type locality, Jingdong Yi Autonomous County in Yunnan. Common name Jingdong frog has been coined for it.
Rana sauteri is a species of true frog endemic to Taiwan. It inhabits low-altitude hill forests and the associated streams. It is an endangered species threatened by habitat loss due to agriculture and infrastructure development. Common names recorded for Rana sauteri include Kanshirei Village frog, Taiwan groove-toed frog, Sauter's brown frog, and Taiwan pseudotorrent frog.
Odorrana junlianensis, also known as the Junlian odorous frog, is a species of frogs in the family Ranidae. It is found in southern China and in the northernmost Laos and Vietnam. Its type locality is the eponymous Junlian County in Sichuan.
Odorrana orba is a species of frog in the family Ranidae. It is found in southeastern Laos and central Vietnam. The specific name orba is Latin for "orphan", referring to the fact that this species was—at the time of species description—known in Vietnam only from a single juvenile.
Rhacophorus rhodopus is a species of frog in the moss frog family (Rhacophoridae). It occurs in south-eastern Asia, from India to southern China, and south to Malaysia. Previously unknown from Laos, it has now been found in Phongsali Province and at Luang Prabang. Its taxonomy is disputed.
The Korean brown frog is a species of frog in the genus Rana. It is native to the Korean Peninsula and Shandong, China.
Hylarana taipehensis is a species of "true frog", family Ranidae. It has several common names, including Taipei frog, Taipei grass frog, two-striped grass frog, or striped slender frog. Following its redelimitation in 2019, its range is now believed to extend from Taiwan and southern China to Vietnam, Laos, Cambodia, and eastern Thailand.
Amolops akhaorum is a species of true frogs discovered in 2007 in the Nam Ha National Protected Area, north-western Laos. It is still only known from its type locality. The specific name akhaorum refers to the local Akha people who helped with the fieldwork of the team who discovered the species.
