Comment

Subgenus Microhyla, Microhyla berdmorei group. Related to Microhyla berdmorei, according to the original publication. See comment under Microhyla borneesis. See accounts by Bourret, 1942, Batr. Indochine: 513–514, and Taylor, 1962, Univ. Kansas Sci. Bull., 43: 542–543. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 99, provided a statement of range. Reported for southwestern Cambodia by Ohler, Swan, and Daltry, 2002, Raffles Bull. Zool., 50: 465–481. Nutphund, 2001, Amph. Thailand: 170, provided a brief characterization and photograph, which Ohler, 2003, Alytes, 21: 102, attributed to Microhyla berdmorei. Stuart, 1999, in Duckworth et al. (eds.), Wildlife in Lao PDR: 49, reported the species in Laos. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 100–101, provided a very brief account, map for Thailand, and photograph. Neang and Holden, 2008, Field Guide Amph. Cambodia: 62, provided a photograph, brief account of identification, ecology, and range in Cambodia. Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 130, detailed the distribution in Thailand. See comparative account by Poyarkov, Vassilieva, Orlov, Galoyan, Tran, Le, Kretova, and Geissler, 2014, Russ. J. Herpetol., 21: 94–101, who considered records of this montane species from Cambodia and Thailand as doubtful, apparently on biogeographic grounds. Niyomwan, Srisom, and Pawangkhanant, 2019, Field Guide Amph. Thailand: 220, provided a brief account (photograph, habitat, and range) for Thailand (in Thai). Gorin, Solovyeva, Hasan, Okamiya, Karunarathna, Pawangkhanant, de Silva, Juthong, Milto, Nguyen, Suwannapoom, Haas, Bickford, Das, and Poyarkov, 2020, PeerJ, 8 (e9411): 1–47, placed this species in their Microhyla annectens group. Hoang, Nguyen, Ninh, Luong, Pham, Nguyen, Orlov, Chen, Wang, Ziegler, and Jiang, 2021, ZooKeys, 1036: 47–74, provided placement in a mtDNA tree.
