Auchenoglanis is a genus of catfishes (order Siluriformes) of the family Claroteidae. It is represented by two living species, A. biscutatus and A. occidentalis (giraffe catfish).[1] Although no apomorphy defines the genus and its monophyly is neither confirmed nor contradicted, it is still considered a valid genus.[2]
Auchenoglanis is a primitive member of the subfamily Auchenoglanidinae and represents a stem group.[2]
Species of this genus occur predominantly in the Nilo-Sudan region, but also in the Congo River, Lakes Mobutu and Tanganyika.[3]
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.[2]
Fossil record
Auchenoglanis is rare in the fossil record compared to other African catfishes.[2] Auchenoglanis includes an extinct species, Auchenoglanis soye from Western Chad.[2] A few other fossils are also attributed to Auchenoglanis with no specific species described.[2]
