| Scientific Name: | Barbus ruasae |
| Species Authority: | Pappenheim & Boulenger, 1914 |
| Taxonomic Notes: | The genus Barbus (Cyprinidae) is restricted to a small number of species mainly inhabiting the European ichthyographic region including Northeast Africa. Most of the African species that are currently included in the genus, taxonomically do not appear to be closely related to the genus Barbus sensu strictu. However, no attempts have yet been made at an adequate nomenclature of the African forms. We therefore follow Berrebi et al. (1996) and use in this paper the term ‘Barbus’ for the cyprinid fish species which were previously considered as Barbus (Seegers et al., unpublished). |

Justification: Known only from Mukungwa river, a fast-flowing river in upper Akagera (Rwanda). Extent of occurrence is less than 100 km² and area of occupancy is less than 10 km². Threatened by water turbidity due to erosion on watershed and agriculture extension leading to a decline in habitat extent and quality. |
