|Comment||Synonymy partly after ZHAO & ADLER 1993, Jiang (2004) and Guo & Deng 2009. Amblycephalus komaii MAKI 1931 has been removed from the synonymy of P. formosensis and revalidated by YOU et al. 2015.|
Similar species: Pareas formosensis and P. chinensis share very similar coloration and scale patterns (Jiang 2004). However, our molecular phylogenetic results indicate that the two species are not especially closely related within Pareas. Pareas formosensis is the sister species to P. hamptoni, and P. chinensis the sister of P. boulengeri. Close examination of maxillary teeth is consistent with this result. Both P. formosensis and P. hamptoni have 7–8 maxillary teeth, while P. chinensis and P. boulengeri have only 4–5 maxillary teeth (Rao and Yang, 1992).
|Etymology||Named after its distribution in Taiwan (= Formosa).|
