Fei, Hu, Ye, and Huang, 2006, Fauna Sinica, Amph. 1: 284–288, provided an account and range map for China.See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 601. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 82–83, provided a brief account including photographs of specimens and habitat. Honda, Matsui, Tominaga, Ota, and Tanaka, 2012, Mol. Phylogenet. Evol., 65: 642–653, reported on strong inter-island genetic differentiation and molecular phylogeography.

Records from the Amami island group are now are transferred to Echinotriton raffaellii. Ozaki, Tominaga, Matsui, Hara, and Nishikawa, 2023, Curr. Herpetol., Kyoto, 42: 9–16, reported on geographic variation in skull morphometrics.
