Eastern Myanmar in the Karin Hills region of the type locality and southern Yunnan (Mengyang), China, from a site near the borders of Laos and Myanmar; Thailand (Mae Hong Son, Chiang Mai, Lampang, Loei, Chaiyaphum, Uthai Thani, Kanchana Buri, and Surat Thani provinces); records from Vietnam, India, and Laos now assigned to other named and unnamed species

Geographic Occurrence

Natural Resident: China, People's Republic of, Myanmar, Thailand


Ohler, Wollenberg, Grosjean, Hendrix, Vences, Ziegler, and Dubois, 2011, Zootaxa, 3147: 28–31, provided a figure, description of the lectotype and an account and either allocated specimens from other than the Karen Hills in eastern Myanmar to other species or did not comment on their status. Stuart, 2005, Herpetol. Rev., 36: 474, noted that the record for Leptolalax pelodytoides for Laos published by Stuart, 1999, in Duckworth et al. (eds.), Wildlife in Lao PDR, was based on Leptolalax bourreti and Leptolalax oshanensis (now reidentified, respectively to Leptolalax eos and Leptolalax minimus by Ohler, Wollenberg, Grosjean, Hendrix, Vences, Ziegler, and Dubois, 2011, Zootaxa, 3147: 39). Delorme, Dubois, Grosjean, and Ohler, 2006, Alytes, 24: 14, noted that Leptolalax lateralis may be conspecific with Leptolalax pelodytoides. There is an extensive literature associated with the name Leptolalax pelodytoides (or Megophrys pelodytoides), for southern China, Vietnam, and Malaysia, but that is not even minimally provisional. Most of these accounts presumably are based on other species or mixed species samples: Account, presumably conflating several species, provided for French Indochina by Bourret, 1942, Batr. Indochine: 208–211, as Megophrys pelodytoides. See Taylor, 1962, Univ. Kansas Sci. Bull., 43: 317–319 (Thailand); Berry, 1975, Amph. Fauna Peninsular Malaysia: 37 (see below), and Inger, Zhao, Shaffer, and Wu, 1990, Fieldiana, Zool., N.S., 58: 5 (India). Karsen, Lau, and Bogadek, 1986, Hong Kong Amph. Rept.: 17, provided a brief account. Yang, 1991, Amph. Fauna of Yunnan: 73–75 (probably based on Leptolalax eos); Fei, 1999, Atlas Amph. China: 102–103, provided a brief account, figure, and map (probably mostly based on Leptolalax eos). See comment by Ohler, Marquis, Swan, and Grosjean, 2000, Herpetozoa, Wien, 13: 74. See brief account and photo by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 77–78 (probably based on Leptolalax minimus). Zhang and Wen, 2000, Amph. Guangxi: 42, provided an account for Guangxi (probably Leptolalax sp.). See also brief account by Zhao and Yang, 1997, Amph. Rept. Hengduan Mountains Region: 49–51. Nutphund, 2001, Amph. Thailand: 78, provided a brief characterization and illustration. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 80–81, provided a very brief account, map for Thailand, and photograph although the species identification is now suspect. Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 112–13, provided specific localities for Vietnam although it is now unclear what the species noted is. Yang, 2008, in Yang and Rao (ed.), Amph. Rept. Yunnan: 39, provided a brief account for Yunnan, China. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 2: 315–320, provided an account and spot map. Chan, Belabut, and Ahmad, 2010, Russ. J. Herpetol., 17: 202–206, doubted the West Malaysia record. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 174, provided a brief account (as Paramegophrys oshanensis) including photographs of specimens and habitat. Grismer, Chan, Grismer, Wood, and Ahmad, 2010, Russ. J. Herpetol., 17: 147–160, reported localities from the Banjaran Bintang Mountains, northwestern peninsular Malaysia. Fei, Ye, and Jiang, 2012, Colored Atlas Chinese Amph. Distr.: 202, provided an account (as Paramegophrys pelodytoides), photographs, and a range map for China. Fei and Ye, 2016, Amph. China, 1: 604–598, provided an account (as Paramegophrys), photographs, and dot map. Li, 2011, Amph. Rept. Guangdong: 23, provided a brief account for Guangdong, China, and photograph. Niyomwan, Srisom, and Pawangkhanant, 2019, Field Guide Amph. Thailand: 128–129, provided a brief account (photograph, habitat, and range) for Thailand (in Thai). Makchai, Chuaynkern, Safoowong, Chuachat, and Cota, 2020, Amph. N. Thailand: 86–87, 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): 31, did not include China in the list of countries inhabited by this species; their listed restricted this species to Myanmar and Thailand. Zug, 2022, Smithson. Contrib. Zool., 653: 27, briefly discussed habitat and range in Myanmar.
