Comment

Japanese species reviewed by Sato, 1943, Monogr. Tailed Batr. Japan: 1–520. Species groups noted in accounts are derived from Thorn, 1968, Salamand. Eur. Asie Afr. Nord: 37 (also Thorn and Raffaëlli, 2000, Salamand. Ancien Monde: 42, who provided accounts for most species in Hynobius). See Ikebe, Kuro-o, Ikebe, Katakura, Izumisawa, and Kohno, 1989, in Matsui et al. (eds.), Curr. Herpetol. E. Asia: 85–90, for phylogenetics of 10 species from Korea and Japan. Matsui, Seto, and Miyazaki, 1985, Japan. J. Genet., 60: 119–123, discussed karyotypic relationships among the Korean and Japanese species. Ikebe, Kuro-o, Ohhashi, Yamada, Aoki, and Kohno, 1989, in Matsui et al. (eds.), Curr. Herpetol. E. Asia: 91–94, also reported on karyotipic relationships. Fei and Ye, 2005, in Fei et al. (eds.), Illust. Key Chinese Amph.: 25–36, provided brief accounts for Chinese species. Fei, Hu, Ye, and Huang, 2006, Fauna Sinica, Amph. 1: 142–175, provided keys, accounts, and diagnoses of Chinese species groups. Chen, Qing, and Zeng, 2008, Sichuan J. Zool., 27: 468–477, discussed systematics and species groups in China. Nishikawa, Jiang, Matsui, Mo, Chen, Kim, Tominaga, and Yoshikawa, 2010, Zootaxa, 2426: 65–67, reported on the molecular phylogenetics of the Chinese species only. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543–583 (see comment in Amphibia record) provided as part of a larger molecular analysis a tree of many of the species Hynobius. Zheng, Peng, Murphy, Kuro-o, Hu, Hu, and Zeng, 2012, Asian Herpetol. Res., Ser. 2, 3: 288–302, reported on mt DNA relationships. Nishikawa and Matsui, 2014, Zootaxa, 3852: 206, provided a tree of relationships for the Japanese members of Hynobius. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 58–75, provided brief accounts, photos, and maps for the species. Sparreboom, 2014, Salamanders Old World: 51–102, reviewed the biology, characteristics, distribution, reproduction, and conservation of the species. Iizuka, Lai, Poyarkov, and Sessions, 2016, Bull. Herpetol. Soc. Japan, 2016: 1–14m discussed phylogeny of the species of Hynobius using cytogenetics, limb development, and life history. See accounts of and key to Chinese species by Fei and Ye, 2016, Amph. China, 1: 153–185. See Igawa, Okamiya, Ogino, and Nagano, 2020, MtDNA, Part B, 5: 2241–2242, who provided a Bayesian inference tree of 18 species of Hynobius. Borzée and Min, 2021, Animals, 11 (187): 1–36, discussed the phylogenetics of Korean Hynobius, resulting in the naming of three new species. Dubois, Ohler, and Pyron, 2021, Megataxa, 5: 1–738, recognized at generic rank the current subgenera Hynobius, Poyarius, Satobius, and Pachypalaminus; I am not immediately recognizing these arbitrary rank changes pending some sense of the community of salamander systematists. Chen, Lin, Yu, Jheng, Lin, Sun, and Ju, 2025, Sci. Rep. (Nature, London), 14 (20898): 1–14, reported on microsatellite markers to assess genetic differentiation of the species of Hynobius endemic to Taiwan: Hynobius arisanensis, Hynobius formosanusHynobius fucusHynobius glacialis, and Hynobius sonani.
