Africa: known only from the upper Malagarasi drainage in Burundi.
Often encountered in swift running waters, but occasionally in more quiet rivulets. At some localities in the Malagarasi drainage, this occurs syntopically with O. malagaraziensis. In smaller affluents, this is found together with several small species of Barbus, Amphilius, Chiloglanis and mastacembelids. Feeds on algae belonging to Bacillariophyceae, Chlorophyceae and Cyanophyceae (Ref. 28906).
