Comment

According to the original publication, this taxon has previously been confused with Tylototriton vietnamensis from Phu Tho Province, Vietnam, and Tylototriton asperrimus and Tylototriton cf. asperrimus from Lai Chau, Lao Cai, Hoa Binh, Phu Tho, and Lac Son provinces, Vietnam. In the Tylototriton (Yaotriton) asperrimus species group of Poyarkov, Nguyen, and Arkhipov, 2021, Taprobanica, 10: 4–22, who discussed phylogenetics. See comments by Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 67. In the Tylototriton asperrimus group of Lyu, Wang, Zeng, Zhou, Qi, Wan, Li, and Wang, 2021, Vert. Zool., Senckenberg, 71: 697–710, who discussed phylogenetics. Raffaëlli, 2022, Salamanders & Newts of the World: 284, provided accounts (as Tylototriton pasmansi and Tylototriton obsti), summarizing systematics, some pending publication, life history, population status, and distribution (including a polygon map).
