A new species of stream-living toad (Anura: Bufonidae: Bufo) from Guangdong, China

Abstract In this work, we describe a new species of genus Bufo , Bufo exiguus sp. nov. from Mt. Nankun, Guangdong Province, China. This new species can be distinguished from all congeners by significant divergences in the mitochondrial 16S rRNA and CO1 genes and by a combination of morphological characters: small body size, tympanum absent, parotoid glands small and olive-shaped, tarsal fold absent, dorsal body with a fine vertebral line and white nuptial spinules present on dorsal and inner surfaces of fingers I and II in males. At present, Bufo exiguus sp. nov. is only known from the slow-flowing montane streams from its type locality and its conservation status should be carefully addressed.
