Abstract
The taxonomy of two species of Pleuronichthys from East Asia was re-examined on the basis of scale characteristics. The lectotype of Pleuronichthys cornutus (Temminck and Schlegel 1846) was shown to be conspecific with Pleuronichthys japonicus Suzuki, Kawashima and Nakabo 2009, being characterized by oval scales, a greater exposed scale area and lower scale counts than a second species, formerly recognized as P. cornutus, but to which Pleuronichthys lighti Wu 1929, formerly considered a junior synonym of P. cornutus, should now be applied. Accordingly, P. japonicus is now considered a junior synonym of P. cornutus.
