Comment

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. Sparreboom, 2014, Salamanders Old World: 365–366, reviewed the biology, characteristics, distribution, reproduction, and conservation of the species. See brief account by Phimmachak, Aowphol, and Stuart, 2015, Zootaxa, 4006: 296–297. Bernardes, Le, Nguyen, Pham, Pham, Nguyen, Rödder, Bonkowski, and Ziegler, 2020, ZooKeys, 935: 121–164, provided a range map. Nishikawa, Sanamxay, Kurita, Hibino, Jono, and Nguyen, 2020, Acad. J. Biol., 42: 135–137, provided an upper elevation record. In the Tylototriton (Yaotritonasperrimus species group of Poyarkov, Nguyen, and Arkhipov, 2021, Taprobanica, 10: 4–22, who discussed phylogenetics and reassigned the Vietnam record to a new species, Tylototriton thaiorum.
