See accounts by Van Kampen, 1923, Amph. Indo-Austral. Arch.: 234; Bourret, 1942, Batr. Indochine: 393–394; and Berry, 1975, Amph. Fauna Peninsular Malaysia: 58–59. Matsui, Wu, and Yong, 1993, Zool. Sci., Tokyo, 10: 691–695, reported on the advertisement call. See brief account and photo by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 87. Nutphund, 2001, Amph. Thailand: 98, provided a brief characterization (as Staurois larutensis) and a photograph. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 106–107, provided a very brief account, map for Thailand, and photograph. Matsui and Nabhitabhata, 2006, Zool. Sci., Tokyo, 23: 731, suggested that the Thailand record of Amolops larutensis, published by Taylor, 1962, Univ. Kansas Sci. Bull., 43: 477–480, probably is a misidentified Amolops panhaiGrismer, Chan, Grismer, Wood, and Ahmad, 2010, Russ. J. Herpetol., 17: 147–160, reported localities from the Banjaran Bintang Mountains, northwestern peninsular Malaysia. Thong-aree, Chan-ard, Cota, and Makchai, 2011, Thailand Nat. Hist. Mus. J., 5: 99–106, reported the species from Bala Forest, Narathiwat, extreme southern Thailand. Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 142, detailed the range in Thailand. Hasan, Islam, Khan, Igawa, Alam, Tjong, Kurniawan, Joshy, Yong, Belabut, Kurabayashi, Kuramoto, and Sumida, 2014, Turkish J. Zool., 38: 389, suggested on the basis of 16S mtDNA divergence that a population from Gombak District, West Malaysia, may represent and unnamed species (possibly now Amolops gerutu, DRF). Sumarli, Grismer, Anuar, Muin, and Quah, 2015, Check List, 11(4, Art. 1679): 12, reported specimens from Lata Tembaka, Mount Teba, and Mount Lawit, Terregganu, West Malaysia, and briefly reported on their morphology and habitat. Chan, Abraham, Grismer, and Grismer, 2018, Zootaxa, 4434: 250–264, recognized two segregate species, Amolops australis and Amolops gerutu, from Peninsular Malaysia, previously confused with this species; the result is that earlier literature on Amolops larutensis needs to be used with caution. See comments on morphology and natural history in West Malaysia by Chan, Muin, Anuar, Andam, Razak, and Aziz, 2019, Check List, 15: 1055–1069. Niyomwan, Srisom, and Pawangkhanant, 2019, Field Guide Amph. Thailand: 320–321, provided a brief account (description, photographs, habitat, and range) for Thailand (in Thai). Chan and Brown, 2020, Zool. J. Linn. Soc., 190: 65–78, reported on landscape genetics. In the Amolops larutensis group of Zeng, Liang, Li, Lyu, Wang, and Zhang, 2020, Mol. Phylogenet. Evol., 146 (106753): 1–9, and Wu, Yan, Stuart, Prendini, Suwannapoom, Dahn, Zhang, Cai, Xu, Jiang, Chen, Lemmon, Lemmon, Raxworthy, Orlov, Murphy, and Che, 2020, Mol. Phylogenet. Evol., 144 (106701): 1–13, who discussed molecular phylogenetics. In the Amolops larutensis group of Jiang, Ren, Lyu, Wang, Wang, Lv, Wu, and Li, 2021, Zool. Res., Kunming, 42: 574–591.
