English Names

None noted.


Known only from Province of Khammouan, Laos, and Nghe An Province, in adjacent Vietnam, 980 to 1000 m elevation. Presumably to be found in the intervening highlands. 


In the Tylototriton asperrimus group according to the original publication. Yuan, Jiang, Lü, Yang, Nguyen, Nguyen, Jin, and Che, 2011, Zool. Res., Kunming, 32: 57–58, suggested that Tylototriton notialis is a junior synonym of Tylototrion asperrimus, but this conclusion was based on fewer data than the original recognition of the species. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 186–187 provided a brief account, photograph, and map and documented the presence of this species in Vietnam, although only in provincial terms. See brief account by Phimmachak, Aowphol, and Stuart, 2015, Zootaxa, 4006: 296–297.
