| Scientific Name: | Barbus microbarbis |
| Species Authority: | David & Poll, 1937 |
| 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this paper the term ‘Barbus’ for the cyprinid fish species which were previously considered as Barbus (Seegers et al., unpublished).Uncertain status: known only from one specimen of 27 cm.Note: Possibility of ingeneric hybridisation has been reported (hybrid of Barbus and Varicorhinus) (De Vos et al. 1990), the effect of Tilapia introductions in Rwanda. |

Justification: Has not been recorded for over 50 years despite regular surveys of the lake. Previously found only in Lake Luhondo (Upper Akagera) and probably in associated small streams. Previous area of occupancy less than 20 km². |
|
| Range Description: | Lake Luhondo (Upper Akagera). |
| Countries: |
Regionally extinct:
Rwanda
|
| Population: | Unknown. |
| Habitat and Ecology: | Probably inhabited both lakes and rivers. Little is known on its biology. |
| Systems: | Freshwater |
| Major Threat(s): | Mortality as a bycatch in fisheries. Introduction of Tilapia and Haplochromis species may have been the reason for extinction of the species in Lake Luhondo (De Vos and Thys van den Audenaerde 1990). |
| Conservation Actions: | Unknown. |
