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]
