Auchenoglanis


Auchenoglanis is a genus of relatively large, up to SL, claroteid catfishes native to various freshwater habitats in Africa.
Auchenoglanis is a primitive member of the subfamily Auchenoglanidinae and represents a stem group.
Species of this genus occur predominantly in the Nilo-Sudan region and Western Africa, but also in the Congo River, Lakes Albert and Tanganyika.
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.

Living species

Following a taxonomic review in 1991, only two living species were recognized in this genus. This is followed by FishBase. A review in 2010 found that there are six additional species, bringing the total to eight, and this is followed by Catalog of Fishes. Genetic studies indicate that additional, currently unrecognized species exist.
Auchenoglanis is rare in the fossil record compared to other African catfishes. Auchenoglanis includes an extinct species, Auchenoglanis soye from Western Chad. A few other fossils are also attributed to Auchenoglanis with no specific species described.
