In the Rhacophorus (Rhacophorus) leucomystax group of Dubois, 1987 "1986", Alytes, 5: 77; see comment under Polypedates. See account by Inger, 1956, Fieldiana, Zool., 34: 413; and Inger, 1966, Fieldiana, Zool., 52: 326–329. See brief account and photo by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 129–130. Malkmus, Manthey, Vogel, Hoffmann, and Kosuch, 2002, Amph. Rept. Mount Kinabalu: 197, provided an account. Das, Jankowski, Makmor, and Haas, 2007, Mitt. Hamburg. Zool. Mus.
