Abstract:
A new species of the genus Tylototriton is described, from Yuexi county, Anhui province, in the south of the Dabie Mountains. It is based on morphological and molecular analysis. The new species is identified as belonging to the Tylototriton asperrimus group and shares a number of similarities with T. wenxianensis, T. broadoridgus and T. dabienicus. The diagnostic characteristics of the new species are as follows: the head length is greater than the width of the head; bony ridges on the head are prominent and necked-in; the distal digit ends, ventral digits, peripheral area of the cloaca and the tail’s lower edge are orange. The result from the molecular analysis of the genus Tylototriton (including the type specimen of the new species) based on three mitochondrial genes (ND1, ND2 and CYTB) indicated that the new species was close to T. wenxianensis, T. dabienicus, and T. broadoridgus, but formed an independent clade. This result was consistent with the morphological analysis above, which supports the theory that the population distributed in the south of the Dabie Mountains, namely in from Yuexi county, Anhui province, represented a distinct species, Tylototriton anhuiensis sp. nov.
