<i>Gekko</i> Genus of lizards

Gekko is a genus of Southeast Asian geckos, commonly known as true geckos or calling geckos, in the family Gekkonidae. Although species such as Gekko gecko are very widespread and common, some species in the same genus have a very small range and are considered rare or endangered.

<i>Hemiphyllodactylus</i> Genus of lizards

Hemiphyllodactylus is a genus of geckos ranging from India and China southward to Southeast Asia and Oceania. Species of Hemiphyllodactylus are commonly known as half leaf-fingered geckos. Many species are known as dwarf geckos or slender geckos.

<span class="mw-page-title-main">Salamandridae</span> Family of amphibians

Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands.

<i>Leptobrachella</i> Genus of amphibians

Leptobrachella is a genus of frogs in the family Megophryidae. Members of Leptobrachella are found throughout Asia including on Borneo and the Natuna Islands. They are sometimes referred to as Borneo frogs, slender-armed frogs, or dwarf litter frogs. The genus contains over 82 species with 25 found in China alone.

<span class="mw-page-title-main">Eastern spadefoot toad</span> Genus of amphibians

Eastern spadefoot toads comprise a genus of the family Megophryidae in the order Anura, and are found in southern China, northeast India, southeast Asia, and islands of the Sunda Shelf as well as the Philippines. They are characterized by a stocky body with slender, short hindlimbs. In identifying species, iris colour is a valuable diagnostic morphological characteristic ; the iris has uniform colour in some species, whereas in other species the upper half is coloured and the lower half is dark.

<i>Theloderma</i> Genus of amphibians

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.

<i>Rhacophorus</i> Genus of amphibians

Rhacophorus is a genus of frogs in the shrub frog family (Rhacophoridae) and the related Hylidae make up the true tree frogs. They are found in India, Japan, China, and Southeast Asia. Over 40 species are currently recognised.

<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>Limnonectes</i> Genus of fork-tongued frogs

Limnonectes is a genus of fork-tongued frogs of about 75 known species, but new ones are still being described occasionally. They are collectively known as fanged frogs because they tend to have unusually large teeth, which are small or absent in other frogs.

<i>Tylototriton verrucosus</i> Species of amphibian

Tylototriton verrucosus is a species of newt found in the Indian subcontinent and Southeast Asia. Common names include: Himalayan newt, crocodile newt, crocodile salamander, Himalayan salamander, red knobby newt.

<i>Tylototriton ziegleri</i> Species of amphibian

Tylototriton ziegleri, also known as Ziegler's crocodile newt or Ziegler's knobby newt, is a species of newt in the family Salamandridae. It is currently known from Hà Giang and Cao Bằng provinces in northern Vietnam, although its actual range probably wider; there is a photograph to suggest it also occurs in Lào Cai Province in Vietnam, and its range likely extends to Yunnan in southern China. Based on molecular genetic data, Tylototriton ziegleri belongs to the "Tylototriton asperrimus group" of newts. The specific name ziegleri honours Thomas Ziegler, a German herpetologist.

Tylototriton panhai is a newt found in Thailand and Laos. It was recently distinguished from Tylototriton shanjing by Nishikawa et al., 2013.

Tylototriton uyenoi, the Chiang Mai crocodile newt, is a newt endemic to Chiang Mai Province, Thailand. It was distinguished from Tylototriton shanjing, the emperor newt, in 2013. The species was named in honor of herpetologist Shun-ichi Ueno. T. uyenoi is one of the few salamander species endemic to Thailand.

<i>Tylototriton shanorum</i> Species of amphibian

Tylototriton shanorum is a newt endemic to Shan State, Myanmar, where it was recorded in Taunggyi.

Tylototriton yangi is a species of salamander in the family Salamandridae endemic to southern Yunnan, China. It is found throughout Honghe and Wenshan Prefectures.

<i>Tylototriton anguliceps</i> Species of salamander

The angular-headed newt, also known as angular-headed crocodile newt, is a species of salamander in the family Salamandridae from Thailand, Laos, and Vietnam. Its unique orange markings help to distinguish it from other species, and also gave it the nickname "Star-Trek newt", as it resembles the ridges on the head of the fictional Klingon species from the television show Star Trek.

Pachytriton inexpectatus is a species of salamander in the family Salamandridae. It is endemic to southern China and found in the Guizhou, Hunan, Guangdong, and Guangxi provinces. Its type locality is Mount Dayao of Jinxiu Yao Autonomous County, Guangxi. Prior to naming of this species in 2011, it was confused with Pachytriton labiatus. It is one of the several species that can appear in the pet trade as paddletail newt. The specific name inexpectatus is Latin meaning "unexpected" and refers to finding a species that is common in pet trade but lacked formal scientific description. Common name Yaoshan stout newt has been coined specifically for this species.

<i>Zhangixalus</i> Genus of amphibians

Zhangixalus is a genus of frogs in the subfamily Rhacophorinae, family Rhacophoridae. They are collectively known as Zhang's treefrogs. They occur in the Eastern Himalayas, southern China, Taiwan, Japan, and southeast Asia.

<i>Boulenophrys</i> Genus of amphibians

Boulenophrys is a genus of frogs in the family Megophryidae. They occur in the China, Mainland Southeast Asia and Northeast India. It had been placed variously as a subgenus or synonymy of Megophrys. Dubois, Ohler and Pyron first recognized that Panophrys is preoccupied and employed Boulenophrys as the generic name rather than Tianophrys under the Principle of First Revisor.

Tylototriton ngoclinhensis, the Ngoc Linh crocodile newt, is a species of crocodile newt native to the Central Highlands region of Vietnam. First discovered in 2018, it was described as a new species in 2023. Due to its small range, the newt is considered to be threatened and it has been proposed for it to be classified as endangered on the IUCN Red List.
