Taxonomic Remarks
The species Barbus degeni Boulenger, 1902 is considered a synonym of Labeobarbus intermedius (Rüppell, 1835) in Eschmeyer (CofF ver. May 2011: Ref. 86870). It is treated here a synonym of Labeobarbus nedgia Rüppell, 1835 according to Nagelkerke & Sibbing (1997: Ref. 35835).

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 11 - 13; Espinhos anais: 0; Raios anais moles: 8. Lower lip forming a distinct median lobe; upper lip well developed, often with a median fleshy lobe; if lobes are absent, often a fleshy 'nose' is present; operculum depth about as large as ventral cheek length; head length less than 1.2 times in body depth.
Body shape (shape guide): fusiform / normal.
Occurs especially over rocky substrates in water of no more than 6 m depth. Is a macro-benthivore: specimens smaller than 15 cm FL mainly eat insect larvae, but switch to a more diverse diet when their size increases: adult insects, mollusks and detritus become more important; large specimens are the only barbs in Lake Tana that eat freshwater crabs of the genus Potamonautes; and also eat some fish (Ref. 35835).
