Auchenoglanis is a genus of claroteid catfishes native to Africa.
Auchenoglanis is a primitive member of the subfamily Auchenoglanidinae and represents a stem group.[1]
Species of this genus occur predominantly in the Nilo-Sudan region and Western Africa, but also in the Congo River, Lakes Mobutu and Tanganyika.[2]
Auchenoglanis species mainly feed on insect aquatic larvae and eventually on small mollusks, alevin, and swimming insects. These feeding habits should also enable them to stand a relatively wide range of ecological conditions.[1]
Species
There are currently three recognized species in this family:[3]
- Auchenoglanis biscutatus (É. Geoffroy Saint-Hilaire, 1809)
- Auchenoglanis occidentalis (Valenciennes, 1840) (Bubu)
- Auchenoglanis senegali Retzer, 2010
Fossil record
Auchenoglanis is rare in the fossil record compared to other African catfishes.[1] Auchenoglanis includes an extinct species, Auchenoglanis soye from Western Chad.[1] A few other fossils are also attributed to Auchenoglanis with no specific species described.[1]
