The purpose of this application, under Articles 23.9 and 81.2 of the Code, is to conserve the generic name Pseudobagrus Bleeker, 1858 for a group of bagrid catfishes (order Siluriformes) by suppressing the senior name Tachysurus La Cepède, 1803. The identity of Tachysurus remained ambiguous until the recent designation of a neotype for Tachysurus sinensis La Cepède, 1803. The designated neotype is a specimen that had until that point been identified as Pseudobagrus fulvidraco (Richardson, 1845). This neotype designation made Tachysurus a senior subjective synonym of Pseudobagrus. The use of the name Tachysurus La Cepède, 1803 in reference to Southeast Asian freshwater bagrid catfishes currently referred to Pseudobagrus would create significant confusion in the literature. It is proposed that the name Tachysurus La Cepède, 1803 be suppressed.
