Hynobius sonani, the Taichū salamander, is a species of salamander in the family Hynobiidae, endemic to Taiwan, where it occurs in the Central Mountain Range above 2750m (9,020feet). Its natural habitats are from open alpine habitats to shaded moist evergreen forests; it breeds in streams.[1]
Adult males are 98mm129mm and females are 90mm105mm in length.[2]
The original specimens used to describe H. sonani (along with H. arisanensis and H. formosanus) were lost in the 1923 Great Kantō earthquake.[3]
Hynobius sonani has very fragmented distribution and is threatened by habitat loss, mainly caused by the development of infrastructure for tourism. It is present in Taroko National Park.
