A new species of the toothed toad Oreolalax (Anura, Megophryidae) from Sichuan Province, China

The toad genus Oreolalax is widely distributed in southwest China and northern Vietnam. A new species of the genus is described from Sichuan Province, China. Phylogenetic analyses based on the mitochondrial 12S rRNA and 16S rRNA gene sequences supported the new species as an independent clade cluste...

description The toad genus Oreolalax is widely distributed in southwest China and northern Vietnam. A new species of the genus is described from Sichuan Province, China. Phylogenetic analyses based on the mitochondrial 12S rRNA and 16S rRNA gene sequences supported the new species as an independent clade clustered into the clade also containing O. nanjiangensis and O. chuanbeiensis. The new species can be distinguished from its congeners by a combination of the following characters: body size moderate (SVL 51.2–64.2 mm in males); head broad; tympanum hidden; interorbital region with dark triangular pattern; belly with marbling; male lacking spines on lip margin; spiny patches on chest small with thick sparse spines in male; nuptial spines thick and sparse; tibio-tarsal articulation reaching beyond nostril when leg stretched forward; toe webbing at base.
