In the Rhacophorus (Rhacophorus) schlegelii group of Dubois, 1987 "1986", Alytes, 5: 77; see comment under Rhacophorus for dissenting opinion regarding the recognition of this group. Considered by some authors (e.g., Inger, 1947, Fieldiana, Zool., 32: 345) to be conspecific with Rhacophorus schlegelii. See comment under Rhacophorus viridis. Removed from the synonymy of Rhacophorus viridis by Kuramoto and Utsunomiya, 1981, Japan. J. Herpetol., 9: 4. Maeda and Matsui, 1990, Frogs Toads Japan, Ed. 2: 154–157, provided an account and suggested a close relationship to Rhacophorus moltrechti from Taiwan. Goris and Maeda, 2004, Guide Amph. Rept. Japan: 119–121, provided an account, map, and photograph.
