Description
A new species of the genus Oreolalax Myers & Leviton, 1962 is described from Sichuan Province, southwest China. Molecular phylogenetic analyses based on mitochondrial gene sequences clustered the new species as an independent clade nested with O. rugosus, O. liangbeiensis, and O. major. The new species could be distinguished from its congeners by a combination of the following characters: body size moderate (39.8–52.8 mm in male); head broad; tympanum absent; interorbital region with dark triangular pattern; 1/3 toes webbed, with broad lateral fringes, belly smooth, brown yellow or medium yellow scattered variable brown spots; skin on dorsum relatively rough with fine tiny and large warts granules; middle pectoral glands are evident in males; flanks with dark-brown warts granules; upper surface of limbs with dark bars; and iris orange above and creamy-white below. The new species inhabits subtropical alpine scrub and swamp.
