Silurus imberbis Gmelin 1789 is a replacement name for Silurus inermis Houttuyn 1782, a primary junior homonym of Silurus inermis Linnaeus 1766. Although S. imberbis has recently been regarded as a junior synonym of Silurus asotus Linnaeus 1758, it is considered here to be conspecific with Inegocia japonica (Cuvier in Cuvier and Valenciennes 1829), based on a comparison of the original description of S. inermis Houttuyn with specimens of I. japonica. Although S. imberbis has priority over I. japonica, an argument for a "reversal of precedence" of the International Code of Zoological Nomenclature is presented, establishing I. japonica as the valid name for the species. Although "Platycephalus inermis Jordan and Evermann 1902" has been regarded as an available name, it is not considered to be available.
