The authorship of Platycephalus japonicus and Platycephalus crocodilus is researched. Although many authors have considered that the authorship of these flatheads can be attributed to Tilesius (1812), we consider that Cuvier in Cuvier and Valenciennes [ex Tilesius] (1829) has valid authorship of them. Platycephalus isacanthus, Platycephalus borboniensis and Platycephalus guttatus were also established by Cuvier in the same publication. The conspecificity of these three species and the precedence of P. japonicus are reconfirmed in this study. Although many authors have recognized the validity of P. guttatus, its holotype is identical to P. crocodilus. We also establish the precedence of P. crocodilus over P. guttatus.
