ABSTRACT

A new species, Brachytarsophrys popei sp. nov., is described based on a series of specimens collected from Mount Jinggang, Jiangxi Province, Taoyuandong Nature Reserve, Hunan Province and Nanling Nature Reserve, Guangdong Province, China. The new species can be easily distinguished from other known congeners by morphology, morphometrics and molecular data of the mitochondrial 16S rRNA gene. It is characterized by its relatively small size with 86.2 mm in snout-vent length in adult female and 70.7 mm–83.5 mm in males; vomerine teeth bearing on two markedly elevated ridges, which projecting behind far beyond the posterior level of the choanae, widely separated by a distance nearly 1.5 times length of one; margin of tongue deeply notched behind; toes about one-third to two-thirds webbed in males, at most one-third webbed in female; the webs extending as a wide fringes along either side of toes; upper eyelid with tubercles, one of which is enlarged and becoming a remarkably prominent, bluntly conical light- yellow horn; black tiny nuptial spines on the dorsal surface of the first finger and second finger base, single vocal sac in males; gravid females bear pure yellowish oocytes; tadpoles with a transverse white stripe on ventral surface and two longitudinal white stripes along the sides of body. The new species represents the fifth known Brachytarsophrys species.

Etymology: The  specific  name  “popei”  is  in  honour  of  the noted American herpetologist Clifford H. Pope (1899–1974), in recognition of his efforts on biodiversity surveys and  research  of  amphibians  and  reptiles  in  Southeast  China.  We  propose  the  standard  name  “Pope’s  Short-legged Toad”, chinese name “Po Shi Duan Tui Chan”.

Distribution: Currently, B.  popei  sp.  nov.  is  distributed  in the middle section of Luoxiao Mountains and Nanling Mountains  in  southern  China,  including  three  type  localities:  the  Mount  Jinggang,  Jiangxi  Province,  the  adjacent  Taoyuangdong  NR,  Hunan  Province,  and  the  Nanling  NR,  Guangdong  Province,  China.  In  addition,  the  Yizhang  County,  Hunan  Province  bordered  with  the  Nanling Nature Reserve, thus, population as B. carinense from Yizhang County of Hunan should be the B. popei sp. nov.
