Content and remarks.

This subgenus includes all known Fire-bellied Newts populations distributed in the Yunnan-Guizhou Plateau in southwestern China. Currently, four nomenclatures have been provisionally documented, i. e. H. (Hy.) chenggongensis ( Kou & Xing, 1983) , H. (Hy.) cyanurus ( Liu, Hu & Yang, 1962) , H. (Hy.) wolterstorffi ( Boulenger, 1905) and H. (Hy.) yunnanensis (Yang, 1979) ( Lyu et al. 2023 a) . However, the exact taxonomic status for these populations / species is still unresolved ( Raffaëlli 2022; Lyu et al. 2023 a). Thus, it is improper to present a key to these nomenclatures before a comprehensive study to precisely delimitate their taxonomic placements.
