Amolops mengyangensis is known with certainty only known from southern Yunnan, China

Amolops mengyangensis is a species of frog in the family Ranidae. It is known with certainty only from its type locality, the eponymous Mengyang in Xishuangbanna Dai Autonomous Prefecture, southern Yunnan province of China. [2] [3] However, if Amolops daorum is its junior synonym, distribution of Amolops mengyangensis would be considerably wider, including the vicinity of Sa Pa in northern Vietnam near the Chinese border, Hong Kong, and Houaphanh Province in eastern Laos, and presumably also including the intervening areas. [2]

Taxonomy

Amolops mengyangensis was described in 1995 based on two males and one female collected in 1957 from Yunnan. [4] The specimens had previously been reported as Amolops chunganensis , [5] and this view was maintained by some later authors. [2] Rana daorum was described in 1995 based on specimens from northern Vietnam. [6] In 2007, Ohler concluded that Rana daorum is a junior synonym of Amolops mengyangensis, [5] but this conclusion was challenged by Stuart, Biju, and others who considered it valid as Amolops daorum. [4] [7] As of late 2018, the Amphibian Species of the World [2] and AmphibiaWeb [8] databases recognize both Amolops mengyangensis and Amolops daorum as valid species.

Description

Males measure 39–40 mm (1.5–1.6 in) in snout–vent length, whereas females can reach 60 mm (2.4 in) in snout–vent length. The snout is long and blunt. The tympanum is distinct and large. The hind limbs are long. The finger and the toe tips bear discs. The toes are partially webbed. Skin is smooth. Preserved specimens are dorsally grayish-blueish and ventrally white. [3]

Habitat and conservation

Amolops mengyangensis is listed as of least concern in the IUCN Red List of Threatened Species, but this assumes that Amolops daorum is part of this species and has a relatively broad distribution. Circumscribed this way, Amolops mengyangensis lives in tropical forest in and near streams at elevations of 680–1,900 m (2,230–6,230 ft) above sea level. [1] The type series of Amolops mengyangensis (sensu stricto) was collected from an elevation of 680 meters. [2] [3]

<i>Amolops</i> Genus of amphibians

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.

<i>Amolops formosus</i> Species of amphibian

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.

<i>Amolops chunganensis</i> Species of amphibian

Amolops chunganensis is a species of frog in the family Ranidae. Its type locality, Kuatun village in Wuyishan, Fujian. It is endemic to central, southern and eastern China where it has a wide but scattered distribution ; records from Vietnam probably refer to Amolops mengyangensis.

<i>Amolops cremnobatus</i> Species of amphibian

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. Another common name is the Lao torrent frog and it has been suggested that it should change to Inger’s Lao torrent frog because new species have been described from Amolops cremnobatus and will therefore avoid confusion.

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.

<span class="mw-page-title-main">Common green frog</span> Species of amphibian

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.
