Hylarana, commonly known as golden-backed frogs, is a genus of true frogs found in tropical Asia. It was formerly considered highly diverse, containing around 84 to 96 valid species, [2] but taxonomic revision resulted in a major change in the contents of the genus, recognizing just four species.
Hylarana are small to large-sized frogs. Males have an average snout-vent length of 27 to 85 mm (1.1 to 3.3 in), while females range from 38 to 92 mm (1.5 to 3.6 in). The nares (nostrils) are oval in shape and covered by a flap of skin. The tympanum is visible but is not covered by a supratympanic fold. Vomerine teeth and a pineal ocellus (parietal eye) are present. The toes are webbed, but the fingers are not. [2]
Former members of the genus Hylarana ranged from Sri Lanka to the Western Ghats of India, through Nepal and southern China and Taiwan, down to Southeast Asia to the Philippines and Papua New Guinea, in Northern Australia, and tropical Africa. [3] Following taxonomic revisions, the genus distribution was restricted to Southern and southeast Asia. [4]
Hylarana belongs to the subfamily Raninae of the true frog family Ranidae. [1] The generic name Hylarana derives from Neo-Latin hyle ('wood' or 'forest') and rana ('frog'). [2] Hylarana was previously considered to be a subgenus of the genus Rana . It was recognized as a distinct genus in 2005. [5] [3] Several genera were further split from Hylarana in 2006, and then treated again as junior synonyms of Hylarana. [1] In 2015, Oliver et al. [6] performed a major taxonomic re-assessment of Hylarana. Their taxonomic reassessment left just four of the former 80–100 species within the genus Hylarana sensu stricto . The rest were transferred to Abavorana, Amnirana, Chalcorana, Humerana, Hydrophylax, Indosylvirana, Papurana, Pulchrana , and Sylvirana . In 2023, Amphibian Species of the World tentatively transferred all species in these genera back to Hylarana pending future studies due to significant taxonomic confusion over the group; however, these changes are not recognized by AmphibiaWeb. [7] [8]
Formerly, the genus consisted of around 84 to 96 valid species. Following a major re-classification, only four species are recognised in the genus Hylarana: [4]
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.
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.
Polypedates is a genus of frogs in the family Rhacophoridae, the shrub frogs and Paleotropic tree frogs. They belong to subfamily Rhacophorinae. Members of this genus are collectively known as whipping frogs. They occur in eastern and southern Asia.
Nyctibatrachus is a genus of frogs endemic to the Western Ghats of southwestern India. Their common name is night frogs. Their scientific name also means "night frog", in reference to their habits and dark color. They are the only extant members of the monotypic subfamily Nyctibatrachinae. Currently, 35 species belong to Nyctibatrachus.
Amnirana is a genus of frogs in the family Ranidae, "true frogs". The genus is primarily found in Sub-Saharan Africa, but one species occurs in parts of southern and southeastern Asia. Some of the African species are widespread but contain undescribed cryptic diversity. Most species have a white upper lip, and the genus is sometimes known as the white-lipped frogs.
Meristogenys is a genus of true frogs from Borneo. Its tadpoles are adapted to fast-flowing mountain streams and easily recognizable by their divided upper lip with ribs on the outside.
Indosylvirana aurantiaca, commonly known as the golden frog, is a species of frog endemic to the Western Ghats of India. The species is also known as the Trivandrum frog, the common wood frog, or the small wood frog.
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.
Humerana lateralis is a species of frog in the family Ranidae. It is found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. It is commonly known as Kokarit frog, yellow frog or (ambiguously) wood frog.
Hylarana tytleri is a frog species in the family Ranidae. It is found in eastern and northeastern India, Myanmar, Bangladesh, and southern Nepal, and possibly at lower elevations in Bhutan. It was formerly placed in Rana, and included in the common green frog. It is probably a close relative of that species nonetheless, and thus placed in the revalidated genus Hylarana, of which H. erythraea is the type species. Common name Theobald's ranid frog has been coined for it, although common names for Indian frogs previously identified as Rana erythraea include yellow-striped frog, leaf frog, and leaping frog.
Raorchestes flaviventris is a species of arboreal, nocturnal, frog of the family Rhacophoridae. It is endemic to the Western Ghats, South India. Its common name is yellow-bellied bush frog.
Pelophylax is a genus of true frogs widespread in Eurasia, with a few species ranging into northern Africa. This genus was erected by Leopold Fitzinger in 1843 to accommodate the green frogs of the Old World, which he considered distinct from the brown pond frogs of Carl Linnaeus' genus Rana.
Sylvirana is a genus of true frogs, family Ranidae, found in South and East Asia, from northeastern India in west to China in the north, Taiwan in the east, and Thailand in the south. Originally proposed as a subgenus of Rana in 1992, it has been considered both a full genus and a synonym of Hylarana. Its current recognition at generic level stems from molecular genetic analyses published in 2015.
Chalcorana is a genus of frogs in the family Ranidae, "true frogs". They are found in Southeast Asia, from Thailand to Malay Peninsula and the Sunda Islands.
Papurana is a genus of frogs in the family Ranidae, "true frogs". They are known from Southeast Asia, New Guinea, and northern Australia. Papurana daemeli is the only ranid frog found in Australia.
Papurana milleti is a species of true frog. Originally described in the genus Rana, then Hylarana and Indosylvirana, it is now placed in Papurana. It is native to Cambodia, China (Yunnan), Thailand, Vietnam, and quite possibly Laos. It is a locally common frog found by ponds and streams in seasonal tropical forests.
Gracixalus is a genus of shrub frogs from south-eastern Asia.
Raorchestes is a genus of frogs in the subfamily Rhacophorinae that are found in mountainous regions of South Asia, Southeast Asia, and southern China. A recent study places Raorchestes as a sister taxon of Pseudophilautus. Before the description of the genus in 2010, species now in Raorchestes had been assigned to genera Ixalus, Philautus, and Pseudophilautus.
Abavorana is a genus of true frogs found in Southeast Asia, namely the Malay Peninsula, Sumatra, and Borneo. Species in this genus were formerly classified in the genus Hylarana, but were reclassified into the new genus Abavorana following a 2015 phylogenetic revision of Hylarana.
