Bagrus is a genus of bagrid catfishes. These are relatively large catfish found in freshwater habitats in Africa,[1] except for the virtually unknown B. tucumanus from South America, which likely is a synonym of Luciopimelodus pati.[2][3]
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.[4]
Species

Eleven living species are placed here:[1]

Bagrus bajad (Forsskål, 1775) (Bayad)
Bagrus caeruleus T. R. Roberts & D. J. Stewart, 1976
Bagrus degeni Boulenger, 1906
Bagrus docmak (Forsskål, 1775) (Semutundu)
Bagrus filamentosus Pellegrin, 1924
Bagrus lubosicus Lönnberg, 1924
Bagrus meridionalis Günther, 1894 (Kampango, Kampoyo)
Bagrus orientalis Boulenger, 1902
Bagrus tucumanus Burmeister, 1861
Bagrus ubangensis Boulenger, 1902
Bagrus urostigma Vinciguerra, 1895 (Somalia Catfish)

A possible fossil Bagrus from about 7 million years ago, found in Late Miocene Baynunah Formation[5] rocks near Ruwais (Abu Dhabi), has been described:[4]

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.[4]
