First records of Microhyla ninhthuanensis Hoang et al., 2021 (Anura, Microhylidae) from China, with implications for this species’ natural geographic distribution

We report Microhyla ninhthuanensis Hoang, Nguyen, Ninh, Luong, Pham, Nguyen, Orlov, Chen, Wang, Ziegler & Jiang, 2021 for the first time in China, from Zhuhai and Zhongshan, Guangdong, based on the molecular and morphological evidence. This extends its geographic range northward and eastward by over 550 km and 500 km, respectively. The hypothesis that this species may have been recently introduced into China through human activities is also discussed based on the haplotype network analysis.
