Paramesotriton, also known as warty newts[1] or Asian warty newts,[2][3] is a genus of salamanders in the family Salamandridae.[1] The genus is found in southwestern and southern China and in northern Vietnam.[1][3] Most of the species are endemic to China, and the majority of them have been described recently, since 2008.[3] The genus includes both pond and stream dwellers.[4]

Taxonomy and systematics

The sister taxon of Paramesotriton is Laotriton. The genus may be divided into two species groups (subgenera), Paramesotriton and Allomesotriton.[1][3]

Description

Paramesotriton have a dark brown dorsum[2] with a prominent vertebral ridge, often also a pair of lateral ridges. The tail is high and laterally compressed.[4] Skin texture varies from relatively smooth to very rough.[2] Paramesotriton hongkongensis has toxic skin and ova, as has been shown for many other salamanders.[5]
