Comment

In the Microhyla heymonsi group, and previously confused with that species, according to the original publication, where external morphology, and molecular markers were discussed. See comment under Microhyla heymonsi for access to literature prior to the naming of this population. Hoang, Nguyen, Phan, Pham, Ninh, Wang, Jiang, Ziegler, and Nguyen, 2022, Eur. J. Taxon., 841: 1–41, provided a discussion of the phylogenetics of the species and provided additional localities. Song, Wu, Huang, Wang, Qi, Huang, Xu, Chan, Sun, and Wang, 2026, Check List, 22: 179–192, provided genetically-confirmed records from Zhuha and Zhongshan, Guangdong, China, discussed natural history, distribution (including a dot map of the range), phylogeography, and previous misidentifications. Tran, Nguyen, Nguyen, Nguyen, and Nguyen, 2026, J. Trop. Biodiversity Biotechnol., 11: 1–16, reported the species from Ba Den Mountain, Tay Ninh Province, Vietnam.
