Description
Tylototriton wenxianensis measures 126-133 mm total length in males, 105-140 mm in females. Head is relatively flattened vertically, with equal length and width. Nostrils are located close to the tip of the snout. No labial folds. Vomerine teeth rows are relatively long, found in / orientation and meet near the inner nasal bone. Jugular folds are very obvious and protruding. Body is cylindrical in shape, with a slightly flattened venter. The skin surface is very rough and covered with uniformly sized bumps. The bumps are somewhat more densely packed at the anterior dorsolateral part of the body; however, this is not very apparent since the size of bumps is constant. Limbs are relatively thin. Toes overlap when limbs are adpressed to the flank. There are four unwebbed toes on each forelimb and five unwebbed toes on each hindlimb. Hands and feet are somewhat flattened, and rounded at the toe tips. Tail length is less than snout-vent length. The tail is flattened vertically with a sharp tip, appears weak, and the tailfin fold is not well defined.

Body and tail are dark brown or black, with conspicuous orange or yellow markings present on the tips of the toes and the ventral tailfin fold. Venter has a lighter tone than the rest of the body.
