Scientific Name: Pareas formosensis
Species Authority: (van Denburgh, 1909)
Common Name(s):
English Formosa Slug Snake
Synonym(s):
Amblycephalus formosensis van Denburgh, 1909
Taxonomic Notes: Jiang (2004) indicated that, based on morphological similarities, P. chinensis should be treated as a synonym of P. formosensis. This assignment is not supported by recent genetic research, which found that P. formosensis is not closely-related to P. chinensis and is instead sister to P. hamptoni (Guo et al. 2011).
