See comment under Hynobius naevius, with which this species was long confused. Tominaga and Matsui, 2007, Zool. Sci., Tokyo, 24: 940–944, noted that this name may apply to a cryptic species but this remains unevaluated (see comment). Tominaga and Matsui, 2008, Zool. Sci., Tokyo, 25: 107–114, provided an extended discussion of this taxon, its type locality, and redescribed the lectotype. Sakamoto, Tominaga, Matsui, Sakata, and Uchino, 2009, Zool. Sci., Tokyo, 26: 35–47, reported on molecular phylogeography on Kyushu. Zheng, Peng, Murphy, Kuro-o, Hu, Hu, and Zeng, 2012, Asian Herpetol. Res., Ser. 2, 3: 288–302, reported on mtDNA evidence for cryptic species diversity. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 72, provided a brief account, photo, and map.
