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this paper the term ‘Barbus’ for the cyprinid fish species which were previously considered as Barbus (Seegers et al., unpublished).Uncertain status: known only from one specimen of 27 cm.Note: Possibility of ingeneric hybridisation has been reported (hybrid of Barbus and Varicorhinus) (De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.

Red List Category & Criteria:	Extinct ver 3.1
Year Assessed:	2006
Assessor/s:	Ntakimazi, G.
Reviewer/s:	Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Programme)
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.

Habitat and Ecology [top]

Habitat and Ecology:	Probably inhabited both lakes and rivers. Little is known on its biology.
Systems:	Freshwater

Threats [top]

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).
