Based on morphological and molecular evidences, we describe a new species of Microhyla (Nanohyla) from Deo Ca Mountain in Vietnam. The new species differs from congeners by high genetic divergences in 12S rRNA and 16S rRNA sequences (9.31–11.28 %), surpassing known genetic distances between other recognized species of the subgenus Nanohyla. The new...
