Comment

Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 184, provided a brief account, photograph, and map. Sparreboom, 2014, Salamanders Old World: 361 (as Tylototriton dawishanensis) and 381–382 (Tylototriton yangi), reviewed the biology, characteristics, distribution, reproduction, and conservation of the species.On the basis of morphology and mtDNA Nishikawa, Rao, Matsui, and Eto, 2015, Curr. Herpetol., Kyoto, 34: 67–71, considered Tylototriton daweishanensis and Tylototriton yangi to be conspecific. Fei and Ye, 2016, Amph. China, 1: 281–284, provided photographs, an account, and range map. Wang, Yuan, Zhong, Li, and Verrell, 2017, Amph. Rept. Conserv., 11(2): 33–43, discussed the reproductive biology of this species within the comparative context of the Tylototriton verrucosus group. Bernardes, Le, Nguyen, Pham, Pham, Nguyen, Rödder, Bonkowski, and Ziegler, 2020, ZooKeys, 935: 121–164, provided a range map. In the Tylototriton (Tylototriton) verrucosus species group of Poyarkov, Nguyen, and Arkhipov, 2021, Taprobanica, 10: 4–22, who discussed phylogenetics. In the Tylototriton verrucosus 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: 311–312, provided an account, summarizing systematics, life history, population status, and distribution (including a polygon map).
