Comment

In the Bufo asper group of Inger, 1972, in Blair (ed.), Evol. Genus Bufo: 107. See Inger, 1966, Fieldiana, Zool., 52: 69-70, for account. Confused by some authors with Bufo asper. See brief account and photo by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 31-32. Malkmus, Manthey, Vogel, Hoffmann, and Kosuch, 2002, Amph. Rept. Mount Kinabalu: 77-80, provided an account. Das, Jankowski, Makmor, and Haas, 2007, Mitt. Hamburg. Zool. Mus. Inst., 104: 149, provided a brief description. Das, 2007, Amph. Rept. Brunei: 28, provided a photograph and a brief account (as Bufo juxtasper). Amram, Zainudin, and Wahid, 2018, Sains Malaysiana, 47: 1-7, reported on the mating call. Haas, Kueh, Joseph, bin Asri, Das, Hagmann, Schwander, and Hertwig, 2018, Evol. Syst., 2: 89–114, documented larval morphology. Haas, Kueh, Joseph, bin Asri, Das, Hagmann, Schwander, and Hertwig, 2018, Evol. Syst., 2: 89–114, provided a brief account of morphology and natural history for the Sabah population. Haas, Das, Hertwig, Bublies, and Schulz-Schaeffer, 2022, Guide to the Tadpoles of Borneo: 123–126, summarized the knowledge of habitat, reproduction, larval morphology and coloration. Herlambang, Riyanto, Munir, Hamidy, Kimura, Eto, and Mumpuni, 2022, Treubia, 49: 78, reported the species from Bunguran I., Natuna Is., Indonesia.
