Comment

See Boulenger, 1920, Rec. Indian Mus., 20: 51; Taylor, 1962, Univ. Kansas Sci. Bull., 43: 395–398, and Bourret, 1942, Batr. Indochine: 265–268, for accounts. Ohler and Dubois, 1999, Zool. Scripta, 23: 276, gave a restricted distribution of Myanmar (Karen) and Thailand (Nakhon Si Thammarat). See identification table by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 84–86, to compare this species with other ranids of the Sunda Shelf region. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 118–119, provided a very brief account, map for Thailand, and photograph. Reported for Pulau Langkawi, Kadeh, northwestern West Malaysia, by Grismer, Youmans, Wood, Ponce, Wright, Jones, Johnson, Sanders, Gower, Yaakob, and Lim, 2006, Hamadryad, 30: 61–74. Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 134, detailed the range in Thailand. Lambertz, Hartmann, Walsh, Geissler, and McLeod, 2014, Zool. J. Linn. Soc., 172: 117–132, compared the head ornamentation of Limnonectes dabanus, Limnonectes gyldenstolpei, Limnonectes macrognathus, and Limnonectes plicatellus and suggested that the name Elachoglossa be restricted to this clade. Aowphol, Rujirawan, Taksintum, Chuaynkern, and Stuart, 2015, Zootaxa, 3956: 258–270, provided a molecular tree and comparative morphological characters of this this species. Manthey and Manthey, 2017, Sauria, Berlin, 39: 35–55, provided a record from Phou Khao Khouay National Biodiversity Conservation Area, Laos. Phimmachak, Sivongxay, Seateun, Yodthong, Rujirawan, Neang, Aowphol, and Stuart, 2018, Zootaxa, 4375: 334, provided a 16s mtDNA tree that placed Limnonectes macrognathus among their samples. Niyomwan, Srisom, and Pawangkhanant, 2019, Field Guide Amph. Thailand: 270–271, provided a brief account (photographs, habitat, and range) for Thailand (in Thai). Mulcahy, Lee, Miller, Chand, Thura, and Zug, 2018, ZooKeys, 757: 95, provided a record from Taninthary Division, southern Myanmar. Makchai, Chuaynkern, Safoowong, Chuachat, and Cota, 2020, Amph. N. Thailand: 63–64, provided photographs, a brief account for Thailand, and a range map. Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 24, suggested that the record from Laos by Manthey and Manthey (2016) requires confirmation. Zug, 2022, Smithson. Contrib. Zool., 653: 22–23, briefly discussed identification, habitat, and range in Myanmar. Ong and Shahriza, 2022, Bioacoustics, 31: 89–91, described the advertisement call.
