Pachytriton inexpectatus

Pachytriton inexpectatus is a species of salamander in the family Salamandridae. It is endemic to southern China and found in the Guizhou, Hunan, Guangdong, and Guangxi provinces. Its type locality is Mount Dayao of Jinxiu Yao Autonomous County, Guangxi. Prior to naming of this species in 2011, it was confused with Pachytriton labiatus (now Paramesotriton labiatus ). It is one of the several species that can appear in the pet trade as paddletail newt. The specific name inexpectatus is Latin meaning "unexpected" and refers to finding a species that is common in pet trade but lacked formal scientific description. Common name Yaoshan stout newt has been coined specifically for this species.
