Abstract
The genus Oreolalax is reported from Vietnam for the first time and a new species is described based on morphological differences, molecular divergence, and phylogenetic placement. Morphologically, the new species is distinguishable from its congeners on the basis of a combination of the following diagnostic characters: size small; tympanum hidden; toes with webbing at base; dorsum with distinct, round, spiny warts; flanks with white, spiny spots; belly and lower surface of limbs smooth, with dark marbling; interorbital region without dark triangular pattern; upper surface of thigh with dark bars; male with black spines present on margin of lower lip, spinal patches on chest small with fine spines, nuptial spines on fingers small, and without vocal sacs. In phylogenetic analyses, the new species is unambiguously nested within the genus Oreolalax.
