Comment

Literature prior to 2019 for Borneo should  be used with caution inasmuch as the concept of Megophrys nasuta prior to that year also included the high-elevation Bornean species Megophrys kalimantanensisMegophrys nasuta was removed from the synonymy of Megophrys montana by Taylor, 1962, Univ. Kansas Sci. Bull., 43: 284-287, where it had been placed by Inger, 1954, Fieldiana, Zool., 33: 223; Inger, 1966, Fieldiana, Zool., 52: 39-46 (but who recognized it as distinct later: Inger and Tan, 1996, Raffles Bull. Zool., 44: 554). Berry, 1975, Amph. Fauna Peninsular Malaysia: 39, discussed the Malaysian populations as Megophrys monticola and Lim and Lim, 1992, Guide Amph. Rept. Singapore: 20, provided a brief account. See brief account and photo by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 81-82. Nutphund, 2001, Amph. Thailand: 81, provided a brief characterization and photograph of a specimen referred to this species from Thailand. Malkmus, Manthey, Vogel, Hoffmann, and Kosuch, 2002, Amph. Rept. Mount Kinabalu: 112-114, provided an account. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 82-83, provided a very brief account, map for Thailand, and photograph. Das, Jankowski, Makmor, and Haas, 2007, Mitt. Hamburg. Zool. Mus. Inst., 104: 155, provided a brief description. Das, 2007, Amph. Rept. Brunei: 38, provided a photograph and a brief account. See brief account by Grismer, 2012, Field Guide Amph. Rept. Seribuat Arch.: 40-42, for the Seribuat Archipelago, West Malaysia. Sumarli, Grismer, Anuar, Muin, and Quah, 2015, Check List, 11(4, Art. 1679): 12, reported specimens from the base of Mount Lawit, Terregganu, West Malaysia, and briefly reported on their morphology and habitat. 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. See comments on morphology and natural history in West Malaysia by Chan, Muin, Anuar, Andam, Razak, and Aziz, 2019, Check List, 15: 1055–1069.
