Fei's Stout Newt; Pachytriton de Fei
Species Description: Nishikawa K, Jiang J-P, Matsui M 2011 Two new species of Pachytriton from Anhui and Guangki, China (Amphibia: Urodela: Salamandridae). Current Herpetology 30:15-31.
This species is most similar to Pachytriton granulosus, both with similar body size and coloration. Pachytriton feii can be distinguished by some morphological characteristics: wider head, larger eyes, thinner tail, longer snout and limbs, and wider vomerine tooth series (Nishikawa et al. 2011).
The color in life is uniformly dark brown on the dorsal side. The ventral side is lighter then the dorsal side. The ventral side has reddish orange markings. The markings are brighter and sharper in the juveniles. The underside of the tail and cloaca are light orange. There are no black spots over the body. When preserved, the dorsal coloration fades and becomes a light brown to cream color. The bright markings on the ventral side fade to cream (Nishikawa et al. 2011).
The dorsolateral side of juveniles tends to have orange spots. Juveniles also have more finely scattered orange markings on the ventral side. The ventral orange markings are obscured against the ventral ground color. While adults have tongues that are connected to the mouth floor, juveniles have a protrusible tongue (Nishikawa et al. 2011).

This species is in the genus, Pachytriton. It is the sister taxon to Pachytriton brevipes (Nishikawa et al. 2011).
The species is named after Dr. Liang Fei of the Chengdu Institute of Biology at the Chinese Academy of Science (Nishikawa et al. 2011).
Several mites were found on limbs and inside the mouth of adults (Nishikawa et al. 2011).
