Comment

See comments under Echinotriton and LiangshantritonFei, Ye, Huang, Jiang, and Xie, 2005, in Fei et al. (eds.), Illust. Key Chinese Amph.: 41-42, provided a key to the species of China. Weisrock, Papenfuss, Macey, Litvinchuk, Polymeni, Ugurtas, Zhao, Jowkar, and Larson, 2006, Mol. Phylogenet. Evol., 41: 855-857, on the basis of DNA sequence data found a monophyletic Tylototriton (in the sense of including Yaotriton and Liangshantriton) to be in a monophyletic group with Echinotriton and Pleurodeles. Zhao, Rao, Liu, Li, and Yuan, 2012, J. W. China Forest. Sci., 41: 85-89, provided an ND2 tree of the species. Stuart, Phimmachak, Sivongxay, and Robichaud, 2010, Zootaxa, 2650: 19–32 , as did Yuan, Jiang, Lü, Yang, Nguyen, Nguyen, Jin, and Che, 2011, Zool. Res., Kunming, 32: 577–584, provided a molecular analysis of Tylototriton asperrimus group (= Yaotriton). Shen, Jiang, and Mo, 2012, Asian Herpetol. Res., Ser. 2, 3: 2130, provided a molecular tree of the Tylototriton asperrimus group (= Yaotriton). Gu, Chen, Wang, Tian, Chen, and Tian, 2012, Acta Zootaxon. Sinica, 37: 20-28, reported on the molecular phylogenetics of the Tylototriton asperrimus group as the subgenus YaotritonNishikawa, Matsui, and Nguyen, 2013, Curr. Herpetol., Kyoto, 32: 34-49, reported on an ND2 gene tree. Nishikawa, Khonsue, Pomchote, and Matsui, 2013, Zootaxa, 3737: 261-279, reviewed the systematics of Tylototriton, noted the equivocal nature  of the evidence for its monophyly, questioned the morphological evidence for the recognition of Yaotriton (which they treated as a synonym or subgenus of Tylototriton), named two new species and noted other populations that likely represent independent lineages. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 180–189, provided brief accounts, photographs, and range maps for the species. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 177–178, provided brief accounts, photographs, and range map. Fei and Ye, 2016, Amph. China, 1: 266–308, provided accounts (as Tylototriton and Yaotriton) for Chinese species; the recognition of Yaotriton as a genus was without comment regarding to studies that did not support recognition of this taxon.
