Paramesotriton labiatus

Subgenus: Paramesotriton
family: Salamandridae
subfamily: Pleurodelinae
Taxonomic Notes: The genera Pachytriton and Paramesotriton have had a confused taxonomic history, complicated by the fact that a number of these salamanders have long been in the pet trade, identified as Paddletailed and Warty Newts, respectively. In 1985 Frost (Amphibian Species of the World) recognized only one Pachytriton, P. brevipes, and 5 Paramesotriton. At present 8 species of Pachytriton and 13 species of Paramesotriton are recognized. The pet trade long identified the following biological entities: Phenotypes Pachytriton A, B, C and D, none of them assignable to P. brevipes. Eventually Pachytriton labiatus was associated with phenotype A, but the other phenotypes were of uncertain taxonomy. In 2011 Nishikawa et al. discovered that the nomen labiatus belongs to a biological entity that had been recently named Paramesotriton ermizhaoi, and Phenotype A was assigned to Pachytriton granulosus (which had been in the synonymy of other taxa). Raffaelli (Les Urodeles de Monde, 2nd Ed 2013) thinks that Phenotypes A are taxonomically heterogenous, and include in addition to Pachytriton granulosus, Pachytriton feii, Pachytriton moi and Pachytriton inexpectatus; Phenotype B is thought to be Pachytriton changi (and we think also Pachytriton xanthospilos); Phenotype C is thought to be Paramesotriton labiatus; Phenotype D is thought to be Paramesotriton archospotus. No members of the genus Paramesotriton (Warty Newts) should be called Paddletailed newts; that name should refer only to Pachytriton (which are also known as Stout Newts). For formal taxonomic history see Amphibian Species of the World website.

Pachytriton labiatus (Unterstein, 1930)

19,8 cm (F). Moins massif que P. brevipes. Parties dorsales brun chocolat à noires, avec ou sans un liseré dorsolatéral interrompu orange rouge. Ventre orange vif à rougeâtre avec des taches noires irrégulières. Bords supérieur et inférieur de la queue orange rouge. Une ou plusieurs taches blanc bleuâtre à l’extrémité de la queue du mâle en rut qui a le cloaque parsemé de papilles. Sud-est de la Chine dans deux aires de distribution discontinues, selon Zhao et al (1993): Guizhou, Guangxi, sud du Hunan, Zheijiang, Anhui. Serait présent avec P. brevipes dans le Hunan et le Guangxi. 229 889 km2 (avec les phénotypes décrits plus bas). LC. L’aire décrite comme discontinue de l’espèce serait peut-être due à la présence des phénotypes A et B. Petits ruisseaux, torrents de montagne entre 50 et 1 800 m. Commun, prélevé abondamment pour la médecine traditionnelle et la terrariophilie.

Même installation que pour P. brevipes. Le mâle poursuit la femelle, lui barre la route puis effectue un mouvement caudal lent en arborant les vives taches de la queue. Si la femelle est consentante, il la devance en s’arc-boutant, pliant et dépliant successivement la queue en arborant les taches. La femelle suit le mâle et récupère le spermatophore. L’observation a eu lieu chez l’auteur par 14 °C début novembre en aquarium en eau courante.
