Hypselotriton (Hypselotriton) Wolterstorff 1934

Subgenus Hypselotriton Wolterstorff, 1934 Type species. Molge wolterstorffi Boulenger, 1905, by original designation. Diagnosis. (1) small to large size; (2) gular fold present; (3) mid-dorsal vertebral ridge continuous; (4) metacarpal and metatarsal tubercles on external side of hands and feet present; (5) postocular orange spot present; (6) blue lateral stripe on tail in breeding males present. 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.
