摘要：

We describe a new species of salamander, Paramesotriton zhijinensis, from Guizhou Province, China. The generic allocation of the new species is based on morphological and molecular characters. In morphology, it is most similar to Paramesotriton chinensis but differs in having distinct gland emitting a malodorous secretion (here named scent gland), a postocular stripe, and two non-continuous, dorsolateral stripes on the dorsolateral ridges. Furthermore, neoteny was observed in most individuals of the new species. This has not been previously reported to occur in any other species of Paramesotriton. Analysis of our molecular data suggests that this species a third major evolutionary lineage in the genus Paramesotriton.
