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]
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]
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]
