Sylvirana
''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. Description ''Sylvirana'' are generally medium-size frogs with robust bodies. They have similar postocular masks as in ''Papurana''. The upper lip is gray, off-white, or occasionally, mottled. The dorsum is shagreened with spicules, or it can be warty. The dorsolateral folds a medium-sized and well-developed, either pale or the same color as the dorsum. The flanks have dark coloration below lateral ridges that fades to pale with well-defined dark spots. Males have paired vocal sac The vocal sac is the flexible membrane of skin possessed by most male frogs and toads. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sylvirana Nigrovittata
''Sylvirana nigrovittata'', also known as the black-striped frog, black-spotted stream frog, sapgreen stream frog, etc., is a species of frog in the family Ranidae. It is found in northeastern India, Bangladesh, Nepal, southern China, Myanmar, Thailand, Cambodia, Laos, and Vietnam. The species was redelimited in 2018, and earlier literature may refer to other species; identifications from India and Bangladesh are still uncertain. ''Sylvirana nigrovittata'' occurs in gentle streams in evergreen forest, including evergreen galleries in deciduous forest areas. The tadpoles develop quiet stream sections. It is a common species. It is threatened by the loss of forest canopy over streams it inhabits, as well as hydrological changes. It is not considered threatened by the IUCN.

Sylvirana Mortenseni
''Sylvirana mortenseni'' is a species of true frog. It is found in Cambodia, Laos, and Thailand. The specific name ''mortenseni'' honours Ole Theodor Jensen Mortensen, the Danish zoologist who collected the holotype A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several ... from the island of Koh Chang. Common names Mortensen's frog and Koh Chang Island frog have been proposed for it. ''Sylvirana mortenseni'' has been recorded in evergreen forest on the lower slopes of the mountains, gallery forest, and heavily disturbed areas and forest edge habitats. Clear-cutting of forests is a threat to it, although it appears to also inhabit disturbed areas.

Sylvirana Malayana
''Hylarana malayana'', the Malaya stream frog, Malay woodfrog, or Malayan dark-side frog, is a frog in the family Ranidae. It is endemic to Myanmar and India.

True Frogs
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 (including Madagascar), and Asia. The Asian range extends across the East Indies to New Guinea and a single species (the Australian wood frog (''Hylarana daemelii'')) has spread into the far north of Australia. Typically, true frogs are smooth and moist-skinned, with large, powerful legs and extensively webbed feet. The true frogs vary greatly in size, ranging from small—such as the wood frog (''Lithobates sylvatica'')—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole stage. However, as in most families of frogs, there is large variation of habitat within the family. There are also arboreal species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
