Amolops daorum is a species of frog in the family Ranidae. [2] [4] 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. [2]

Etymology

The specific name daorum refers to the Dao people of northern Vietnam. [3] Common name Dao frog has been coined for this species. [2]

Taxonomy

Amolops daorum was described in 2003 as Rana daorum based on specimens from northern Vietnam. [3] In 2007, Ohler concluded that it 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. [6] [7] As of late 2018, the Amphibian Species of the World [2] and AmphibiaWeb [4] databases recognize Amolops daorum as a valid species. Meanwhile, placement of this species in the genus Odorrana appears to have been caused by a DNA sample allegedly representing this species actually coming from Odorrana hmongorum . [2]

Description

Adult males measure 32–38 mm (1.3–1.5 in) and adult females 53–58 mm (2.1–2.3 in) in snout–vent length. The body is dorsoventrally compressed. The tympanum is distinct and round. The finger and the toe tips bear discs. The toes are fully webbed. The dorsum is green and occasionally has black spots. The flanks are brown and bear at least one large white glandular spot. A white lip stripe runs from the nostril to above the arm insertion. The tympanum and the loreal region are dark brown. The venter is creamy white. [3]

Habitat and conservation

The type series of Amolops daorum was collected from and near streams: the males were on partially submerged rocks in cascades as well as in vegetation adjacent to the streams, whereas females were found slightly farther away from streams in denser vegetation. The elevation at the locality was 1,400 m (4,600 ft) above sea level. [3]

As of late 2022, Amolops daorum has been assessed as least concern an independent species for the IUCN Red List of Threatened Species but included in Amolops mengyangensis. [1]

<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 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.

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.

<i>Amolops spinapectoralis</i> Species of frog

Amolops spinapectoralis is a species of frog in the family Ranidae, the "true frogs". It is at present only known from a few locations in central Vietnam—that is, it is endemic to Vietnam—but it is likely to be found more widely in the Vietnamese Central Highlands as well as in the adjacent southeastern Laos and northeastern Cambodia. The specific name spinapectoralis is derived from Latin spina for "thorn" and pectoralis for "of the breast" and refers to the pectoral spines in adult males. Common name spinyback torrent frog has been coined for it.

Odorrana absita is a species of frog in the family Ranidae. It is found in southern Laos and central Vietnam. It was originally described in genus Huia. Its type locality is Xe Sap National Biodiversity Conservation Area in southern Laos.

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. 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.

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.

Odorrana banaorum is a species of frog in the family Ranidae that is known from Vietnam and Cambodia.

Odorrana bolavensis is a species of frog in the family Ranidae. It is endemic to the Bolaven Plateau, Laos. Its natural habitats are wet evergreen forest. It can be found at night on rocks and vegetation along rocky streams, occasionally on leaf-litter or tree branches away from streams.

<i>Odorrana graminea</i> Species of amphibian

Odorrana graminea, the large odorous frog, inhabits fast-flowing streams in elevated mountainous regions of Southern China and Northern Indochina. It is one of 56 species in the genus Odorrana. Male O. graminea are noted for their ultrasonic call characteristics and are one of three frog species able to detect ultrasonic frequencies, likely evolved to facilitate communication amidst noisy streams and waterfalls. Studies on O. graminea courtship vocalizations suggest female preference for increased proportion of nonlinear vocal phenomena (NLP).

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.

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 leporipes is a species of frog in the family Ranidae. It is endemic to Guangdong province of China and only known from its type locality, "Lung Tao Shan" in northern Guangdong. It is only known from the original species description; the type series is presumed lost and the photographs of the holotype are now the iconotype.

<i>Odorrana livida</i> Species of frog

Odorrana livida, also known as the green mountain frog, green cascade frog, Tenasserim frog, bright frog, large odorous frog, or large-eared rock frog, is a species of frog in the family Ranidae. It is known with certainty only from its neotype locality at the Dawna Range in Myanmar, near the border to Thailand, but molecular data suggest that it is present in northeastern India and in peninsular Thailand too, while records from China refer to other species. In much of the literature, this species has been confused with other species, including Odorrana graminea.

Odorrana morafkai is a species of frogs in the family Ranidae. It is found in eastern Cambodia, southern Laos, and central Vietnam. This frog is highly unusual because it turns from its daytime green color to brown at night.

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.

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.
