[Ichthyology • 2016] Redescriptions of Two Closely related East Asian Flatfish Species of the Genus Pleuronichthys, Pleuronichthys lighti & P. cornutus

(A–C) Pleuronichthys lighti Wu, 1929
(F–H) Pleuronichthys cornutus (Temminck & Schlegel, 1846)


Because of the taxonomic confusion, including misapplication of their scientific names, resulting from the morphological similarity of two East Asian flatfish species, Pleuronichthys lighti Wu, 1929 and Pleuronichthys cornutus (Temminck & Schlegel, 1846), both species are redescribed, with particular emphasis on some new key characters. New common names are proposed for each species.

Keywords: Pisces, Pleuronichthys lightiPleuronichthys cornutus, redescription, morphology, scale

Pleuronichthys lighti Wu, 1929
(New English name: Common frog flounder)

Pleuronichthys cornutus (Temminck & Schlegel, 1846)
(New English name: Phantom frog flounder)
