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]

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]
