Teugels et al. (1991)
considered the genus Auchenoglanis to be comprised of
two valid species: A. biscutatus and A. occidentalis..
Due to the work carried out recently (2010) by Michael Retzer
there are now 8 in this genus with six new species, A. acuticeps,
A. biscutatus, A. occidentalis, A. sacchii,
A. senegali, A. tanganicanus, A. tchadiensis
and A. wittei. The main description
for A. biscutatus is that the body and adipose fin in
adults is either light brown or grey with small, distinct spots
on the rayed fins that do not form bands. The shape of the nuchal
plate is also distinctive from all other congeners in the genera.
Commonly occurs in running water, lakes and submerged vegetation
in the Sudd, rare in fringing vegetation. Feeds on the bottom
on mud, debris, insects, notably chironomid larvae and mollusks.
Gravid fish are recorded throughout the year with a peak in the
dry season. The species depicted in the thumbnail image was originally
thought to be a a juvenile of A. occidentalis. |
