The isolated population of Yaotriton from Hunan; which has previously been considered T.asperrimus by morphology, but which is genetically closer to and distinct from T.wenxianensis, has been described as a new species, Tylototriton broadoridgus. It is rather inelegantly named for its broad dorsal ridge. The paper includes genetic, morphological, and ecological data, as well as comparative photos.
As I have previously suggested here, the authors have also recommended elevating T.dabienicus to full species.

Abstract
A new species of the genus Tylototriton is described in this article based on morphological and genetic evidence. The new species is identified belonging to the T. asperrimus group and is similar to T. wenxianensis. The diagnostic characters of the new species are as follows: dorsal ridge broad and thick, its width approximately equal to eye diameter (P < 0.001); tail height greater than width at base of tail (P < 0.001); no villous genital papilla found inside the male anal fissure; nodule-like warts, along lateral margin of the trunk, bulge and forming tubercles, and thin and transverse striae present between the tubercles.
