Comments: Known from Lake Kivu, Rusizi basin and Middle Akagera (Ref. 27626, 46152). A record by Verbeke (1957) of Barbus cf. duchesni Boulenger, 1902 (a junior synonym of B. intermedius Rüppell, 1836) from Lake Kivu refers to this species. Hulot (1956) reported the group B. bynni (Forskal, 1775) - B. radcliffi (Boulenger 1903)- B. altianalis from Lake Kivu which refers in fact to the single B. altianalis. A record of B. victoriae Boulenger, 1908 (junior synonym of B. marequensis Smith, 1841) from the Middle Akagera by Mahy (1977) is a misidentification for one of the three large barbs occuring in this system (Ref. 46152).

Africa: known from the Middle Akagera (Ref. 27626), Rusizi River, Lake Kivu, Lake Edward, Lake George, Lake Victoria and Lake Kyoga drainages, and northern part of Lake Tanganyika (Ref. 27626, 107916).

Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 3; Mjukstrålar i ryggfenan (totalt) : 9 - 11; Taggstrålar i analfenan: 2 - 3; Mjukstrålar i analfenan: 5 - 6. The anterior barbel reaches the middle of the eye but in general, it is very short, not reaching the anterior side of the eye; the posterior barbel always reaches beyond the anterior eye, sometimes including the anterior side of the operculae; lips well-developed. Sometimes, an outgrowth is present on the snout (Ref. 27626).

In Lake Victoria drainage: inshore waters and affluent rivers (Ref. 4903, 34290). Young occur in shoals (Ref. 36900) in riverine habitats while adults occur in both riverine and lacustrine habitats (Ref. 34291). Swims upstream to spawn (Ref. 36900), probably in swift, rocky upper reaches of rivers (Ref. 34291). Feeds on gastropod molluscs, insects, plants, fishes and crustacea (Ref. 12526). In lakes Edward and George: in shallow water (Ref. 4903). In Rusizi River system: migrates to small upstream rivers to spawn (Ref. 87863). Oviparous (Ref. 205). A food fish for humans (Ref. 4537), but not of great economic importance (Ref. 4903).
