Labeobarbus somereni, or Someren's barb,[4] is a species of ray-finned fish in the family Cyprinidae. It is found in Burundi, Rwanda, Tanzania, and Uganda. Its natural habitat is rivers. It is not considered a threatened species by the IUCN. Local names for the fish in Rwanda include ikinanga, inkwenwe (Middle Akagera), ifurwe (Satinsyi) and urwozi (Nyabarongo).[5]

It was first described by George Albert Boulenger in 1911. Its holotype was caught by Victor Van Someren and its type locality was described as: "the Sebwe River, a snow-water stream on Mount Ruwenzori, in Uganda, at an altitude of 6,000 feet (1,800 m)."[2] The holotype is at the Natural History Museum, London.[6][7] It was initially placed in the genus Barbus but is now classified as a Labeobarbus species.[8][9] It might be able to hybridize with L. ruwenzorii,[10] and it might be a senior synonym of L. mirabilis.[11][9]

In Tanzania, it has been recorded at high altitudes in the headwaters of rivers including the Victoria River, Tanganyika River, Kagera River, and the Malagarasi River.[12] In Rwanda it has been recorded in the Ruzizi basin and the Upper and Middle Akagera River, on either side of the Rusumo Falls.[4] The International Union for Conservation of Nature designate L. somereni as a least-concern species, saying it is "relatively widespread", although it's possible some subpopulations might be at risk from various local threats such as increased farming.[1] It is omnivorous, although primarily herbivorous; it mostly eats aquatic plants and filamentous algae.[13]
