The Ethiopian highlands seem to be a centre of species diversity of the genus Garra on the African continent.
Out of the seventeen species reported from Africa (Stiassny &G etahun 2007) eleven occur in Ethiopia.
Most studies so far conducted on the genus Garra in Ethiopia focused mainly on the major river basins, while small isolated basins are less explored.
Our study on an isolated basin in south westem Ethiopia revealed a previously undescribed species, herein described as Garra chebera.
