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.
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.
Tylototriton is a genus of newts known as crocodile newts or knobby newts. About 38 known species are in this genus. Many species have been described just recently. They range from northeastern India and Nepal through Burma to northern Thailand, Laos, Vietnam, and southern China.
The Pyrenean brook salamander or Pyrenean newt, , is a largely aquatic species of salamander in the family Salamandridae. It is found in the Pyrenees of Andorra, France, and Spain. The IUCN lists it as least concern.
Neurergus is a genus of salamanders, more specifically newts, in the family Salamandridae. They are found in the Middle East, and are kept and bred in captivity for their bright colors. In nature, they inhabit streams and small rivers, and the surrounding forests or shrublands. All of the Neurergus are considered threatened species, primarily due to destruction of habitat and overcollection for the pet trade.
The Laos warty newt is a species of salamander in the family Salamandridae. It is found only in the Saysomboun Special Zone and Phou Kout District in Xiangkhouang Province, Laos. Its natural habitats are subtropical or tropical dry shrubland and rivers. In 2014, it is classed as Endangered.
The black knobby newt is a species of salamanders in the family Salamandridae found in China and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, freshwater marshes, and intermittent freshwater marshes. It is threatened by habitat loss and overharvesting.
The Hainan knobby newt is a species of salamander in the family Salamandridae. It is found only in the island of Hainan, China. It is known from the Wuzhi Mountains, Diaoluoshan, and Jianfengling. All these locations are nature reserves. Nevertheless, the species is threatened by habitat loss and degradation due to agriculture, clear-cutting and infrastructure development for tourist activities.
The red-tailed knobby newt or Kweichow (crocodile) newt is a species of salamander in the family Salamandridae. It is found in western Guizhou and north-eastern Yunnan, China. It is most closely related to emperor newt and Himalayan newt.
The Taliang knobby newt is a species of salamander in the family Salamandridae. It is found only in southern Sichuan, China. It inhabits densely vegetated forested valleys, where it breeds in pools, ponds and paddy fields. It is a common species within its confined range.
The Wenxian knobby newt or Wenxian knobby salamander is a species of salamander in the family Salamandridae. It is endemic to central China. Its type locality is Wen County in Gansu, or in Chinese: 文县; pinyin: Wénxiàn, hence the name.
A newt is a salamander in the subfamily Pleurodelinae. The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult. Adult newts have lizard-like bodies and return to the water every year to breed, otherwise living in humid, cover-rich land habitats.
Tylototriton vietnamensis, the Vietnamese crocodile newt or Vietnamese knobby newt, is a species of newt in the family Salamandridae. It is known from four localities in northern Vietnam where it occurs in and near ponds within dense bamboo vegetation. It is quite likely that it also will be found in adjacent areas of China and possibly Laos. It is possible that specimens earlier identified as T. asperrimus are in fact T. vietnamensis. However, based on molecular genetic data, its closest relative is T. hainanensis.
Tylototriton notialis, also known as the Laos knobby newt, southern crocodile newt, or Khammouan crocodile newt, is a species of newt in the family Salamandridae. It is only known from Khammouane province, central Laos. The Vietnamese record has been described as a new species, Tylototriton thaiorum.
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.
Tylototriton himalayanus is a species of salamander in the family Salamandridae. It is known from the Ilam District in eastern Nepal, Darjeeling in northwestern India, and western Bhutan. It is one of the only two species of salamanders found in India.
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.
