First Record of Megophrys gigantica Liu, Hu et Yang, 1960 (Anura: Megophryidae) from Vietnam

Based on our recent field research in Lao Cai and Son La provinces, Vietnam, we record Megophrys gigantica for the first time from outside of China. The newly collected specimens from Vietnam slightly differs from the type series from China in having a smaller head width in males (32.4 versus 34–42 mm) and a smaller size in females (SVL 97.3 versus 110.4–115.4 mm). In terms of genetic divergence, the specimens from Vietnam are separated from those from Yunnan, China by 0.1% based on the 16S rRNA fragment. Our finding brings the species number of the genus Megophrys to 20 in Vietnam.
