See accounts(as Rhacophorus eiffingeri) by Inger, 1947, Fieldiana, Zool., 32: 345; and Nakamura and Ueno, 1963, Japan. Rept. Amph. Color: 61-62. Considered a junior synonym of Ixalus japonicus Hallowell, 1860, by Wolf, 1936, Bull. Raffles Mus., 12: 166, but this was rejected by Liem, 1970, Fieldiana, Zool., 57: 95. See Zhao and Adler, 1993, Herpetol. China: 152, for discussion of the original description. Fei, 1999, Atlas Amph. China: 264-265, provided a brief account, figure, and map. Maeda and Matsui, 1990, Frogs Toads Japan, Ed. 2: 162-165, provided an account, and noted that the species likely did not belong in Chirixalus, a position formalized by Wilkinson, Drewes, and Tatum, 2002, Mol. Phylogenet. Evol., 24: 272. Goris and Maeda, 2004, Guide Amph. Rept. Japan: 113-115, provided an account (as Chirixalus eiffingeri), map, and photograph. Kishimoto and Hayashi, 2017, Curr. Herpetol., Kyoto, 36: 37–45, reported on embryonic and larval development stages. Dufresnes and Litvinchuk, 2022, Zool. J. Linn. Soc., 195: 735, noted that nominal Kurixalus eiffingeri is composed of three mtDNA lineages, one (Kurixalus eiffingeri) from the southern Ryukyus of Japan, one (Kurixalus pollicaris) from central and western Taiwan, and an unnamed species, which they referred to as Kurixalus cf. eiffingeri, from northern Taiwan.
