See Dring, 1979, Bull. Brit. Mus. (Nat. Hist.), Zool., 34: 181–244, for discussion of populations; see also Berry, 1975, Amph. Fauna Peninsular Malaysia: 43. See brief account by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 30. Nutphund, 2001, Amph. Thailand: 74, provided a brief characterization, but unfortunately pictured a juvenile Ingerophrynus parvus as of this species, according to Ohler, 2003, Alytes, 21: 101, rendering the sole Thailand record questionable (Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 19). Chan-ard, 2003, Photograph. Guide Amph. Thailand: 88–89, provided a very brief account, map for Thailand, and photograph. See comments regarding distribution by Matsui, Khonsue, and Nabhitabhata, 2005, Zool. Sci., Tokyo, 22: 813. Wood, Grismer, Ahmad, and Senawi, 2008, Herpetologica, 64: 321–340, provided comparative information for this and other species from the Malayan Peninsula. Grismer, Chan, Grismer, Wood, and Ahmad, 2010, Russ. J. Herpetol., 17: 147–160, reported localities from the Banjaran Bintang Mountains, northwestern peninsular Malaysia. Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 127, detailed the range in Thailand. Sumarli, Grismer, Anuar, Muin, and Quah, 2015, Check List, 11(4, Art. 1679): 6, suspected that a record of Ansonia malayana from Mount Tebu, Terengganu, Malaysia probably applies to Ansonia latifiNiyomwan, Srisom, and Pawangkhanant, 2019, Field Guide Amph. Thailand: 174–175, provided a brief account (photographs, habitat, and range) for Thailand (in Thai).
