Removed from the synonymy of Philautus aurifasciatus, by Dring, 1987, Amphibia-Reptilia, 8: 45, where it had been placed by Inger, 1966, Fieldiana, Zool., 52: 341. See accounts by Inger, 1954, Fieldiana, Zool., 33: 402-404, and Brown and Alcala, 1994, Proc. California Acad. Sci., Ser. 4, 48: 185-220 (who considered it to be in the Philautus aurifasciatus group). See Dring, 1987, Amphibia-Reptilia, 8: 45, and Inger and Stuebing, 1992, Malayan Nat. J., 46: 41-51, for Bornean records. See comment under Philautus aurifasciatus. See brief account by Malkmus and Riede, 1996, Sauria, Berlin, 18: 27-37. See identification table by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 122-123, to compare this species to other rhacophorids of the Sunda Shelf region. Malkmus, Manthey, Vogel, Hoffmann, and Kosuch, 2002, Amph. Rept. Mount Kinabalu: 186-187, provided an account. See statement of geographic range, habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 634. Dehling, 2010, Salamandra, 46: 69-70, suggested that populations on Borneo assigned to Philautus longicrus may be correctly assigned to Philautus juliandringi or to unnamed species in the Philautus aurifasciatus group.
