Bagrus is a genus of bagrid catfishes. These are relatively large catfish found in freshwater habitats in Africa, except for the virtually unknown B. tucumanus from South America, which likely is a synonym of Luciopimelodus pati.Koerber, S.; and T.

Taxonomy The present scientific name Bagrus was first proposed by Louis Augustin Guillaume Bosc in 1816 for the bayad and its closest relatives. Although in 1809, Geoffroy Saint-Hilaire had already separated this fish in his new genus Porcus. But this was overruled by the ICZN, so that the junior synonym could continue to be used.Ferraris (2007)

A possible fossil Bagrus from about 7 million years ago, found in Late Miocene Baynunah Formation"Bahnunah" is a variant transliteration or lapsus rocks near Ruwais (Abu Dhabi), has been described: Bagrus shuwaiensis Forey & Young, 1999 However, it is not quite clear whether it belongs in Bagrus or some other Bagridae genus, or even in the Claroteidae.
