Auchenoglanis is a genus of relatively large, up to 70 cm (2.3 ft) SL, claroteid catfishes native to various freshwater habitats in Africa.[1]
Auchenoglanis is a primitive member of the subfamily Auchenoglanidinae (also includes Notoglanidium and Parauchenoglanis) and represents a stem group.[2]
Species of this genus occur predominantly in the Nilo-Sudan region and Western Africa, but also in the Congo River, Lakes Albert 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]
Living species
[edit]Following a taxonomic review in 1991, only two living species (marked with a star* in the list) were recognized in this genus.[3] This is followed by FishBase.[1] A review in 2010 found that there are six additional species, bringing the total to eight,[4] and this is followed by Catalog of Fishes.[5] Genetic studies indicate that additional, currently unrecognized species exist.[6]

Fossil species
[edit]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]
