Ziegler's crocodile newt, Tylototriton ziegleri, is a species of newt in the family Salamandridae. [1] [2] It is so far known from Hà Giang and Cao Bằng provinces in northern Vietnam; there is a photograph to suggest it also occurs in Lào Cai Province. Based on molecular genetic data, Ziegler's crocodile newt belongs to the Tylototriton asperrimus group of knobby newts. [1]

Newt Animal

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.

Salamandridae family of amphibians

Salamandridae is a family of salamanders consisting of true salamanders and newts. Currently, 74 species have been identified in the Northern Hemisphere - Europe, Asia, the northern tip of Africa, and North America. 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.

Hà Giang Province Province in Northeast, Vietnam

Hà Giang is a province in the Northeast region of Vietnam. It is located in the far north of the country, and contains Vietnam's northernmost point. It shares a 270 km long border with Yunnan province of southern China, and thus is known as Vietnam's final frontier. The province covers an area of 7,945.8 square kilometres and as of 2008 it had a population of 705,100 people.

Ziegler's crocodile newt is considered to be basically terrestrial outside the breeding season. The single known female was 71 mm (2.8 in) in snout–vent length (SVL); males were 54–68 mm (2.1–2.7 in) SVL. [1]

<i>Leptolalax</i> genus of amphibians

Leptolalax is a genus of frogs in the family Megophryidae. They are sometimes known as Asian toads, metacarpal-tubercled toads, or slender litter frogs, although many species-specific common names do not follow these conventions, and many species do not have common names. They are widely distributed in southeastern and eastern Asia, from southern China and northeastern India to the Malay Peninsula and Borneo. Leptolalax are typically small and have a cryptic colour pattern and no obvious morphological characters useful in systematic studies. Consequently, both molecular genetic analyses and analysis of advertisement calls by male frogs have been important in identifying new species.

Anderson's crocodile newt, Anderson's newt, Ryukyu spiny newt, or Japanese warty newt is a species of salamander in the family Salamandridae found in the Ryukyu Islands of Japan, and, at least formerly, Mount Guanyin in northern Taiwan, where it is now believed to be extinct.

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.

<i>Ichthyophis nguyenorum</i> species of Amphibia

Ichthyophis nguyenorum is a species of caecilian in the family Ichthyophiidae. They were first found in Kon Plông District, Kon Tum Province, central Vietnam, in 2006, and formally described in 2012. The species is now also known from the Cat Tien National Park in the Lam Dong Province, southern Vietnam, and is presumed to occur more widely in suitable habitat in central and southern Vietnam as well as in eastern Cambodia.

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, the Laos knobby newt, is a species of newt in the family Salamandridae. It is only known from its type locality in the Nakai-Nam Theun Biodiversity Conservation Area, Khammouane Province, central Laos. The type locality is an evergreen mixed deciduous–pine forest; the newts were found in and near a small stream. It is likely that Laos knobby newt will also be found in adjacent areas of Vietnam. Based on molecular genetic data, it belongs to the Tylototriton asperrimus group of knobby newts. Laos knobby newt is a small newt, with total length of about 11–14 cm (4.3–5.5 in).

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.
