The genus is found in southwestern and southern China and in northern Vietnam. Most of the species are endemic to China, and the majority of them have been species description, described recently, since 2008. The genus includes both pond and stream dwellers. Taxonomy and systematics The sister taxon of ''Paramesotriton'' is ''Laotriton''. The genus may be divided into two species groups (subgenera), ''Paramesotriton'' and ''Allomesotriton''. Description ''Paramesotriton'' have a dark brown Dorsum (anatomy), dorsum with a prominent vertebral ridge, often also a pair of lateral ridges. The tail is high and laterally compressed. Skin texture varies from relatively smooth to very rough. ''Paramesotriton hongkongensis'' has toxic skin and ova, as has been shown for many other salamanders. Species ''Paramesotriton'' contains the following 14 species: * ''Paramesot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salamandridae
Salamandridae is a Family (biology), 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. Nearly all salamandrids produce a potent toxin in their skin, with some species being deadly to many other animal species. With a few exceptions, salamandrids have patterns of bright and contrasting colours, most of these are to warn potential predators of their toxicity. They have four well-developed limbs, with four toes on the fore limbs, and (in most cases) five toes on the hind limbs. They vary from in length. Many species within this family reproduce by method of internal fertilization. Additionally, there are many species-specific courtship rituals t ...

Tam Dao Salamander
The Tam Dao salamander, Vietnamese salamander, or Vietnam warty newt (''Paramesotriton deloustali'') is a species of salamander in the family Salamandridae found only in Vietnam and Yunnan, China. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It is threatened by habitat loss and poaching Poaching is the illegal hunting or capturing of wild animals, usually associated with land use rights. Poaching was once performed by impoverished peasants for subsistence purposes and to supplement meager diets. It was set against the huntin .... Populations Within Northern Vietnam, two groups of the species exist, a west and an east group, which is consistent with a hypothesis that the ''Paramesotriton'' genus diverged along the west and east. The two populations inhabit similar environments, but have shown differences in their ecological niches. Conservation While the Tam Dao salamander may be li ...

Paramesotriton Hongkongensis
The Hong Kong warty newt or Hong Kong newt (''Paramesotriton hongkongensis'', see alsthe synonyms is a species of salamander (newt) found in Hong Kong. Once thought to be endemic to the territory, the species has also been found in the coastal parts of Guangdong Province. It is the only Urodela living in Hong Kong. This newt is considered by some naturalists as a subspecies of '' Paramesotriton chinensis''. However, some disagree with such a classification based on the disjunctive distribution of the two, and the differences in their physical appearance and habitat preference. Description The snout-to-tail length of the newt is about 11 to 15 cm. Its body colour ranges from light to dark brown, with patches of orange markings scattered on the ventral side. The patterns of the patches are unique for each individual, resembling the fingerprints of humans. Small granules can be found throughout the body.
