Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA ACTINOPTERYGII CYPRINIFORMES CYPRINIDAE

Scientific Name: Barbus sexradiatus
Species Authority: Boulenger, 1911
Common Name/s:
English – Kavirondo Barb
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this paper the term ‘Barbus’ for the cyprinid fish species which were previously considered as Barbus (Seegers et al., unpublished).A dubious species only known from the holotype (Seegers et al., unpublished).

Assessment Information [top]

Red List Category & Criteria: Data Deficient     ver 3.1
Year Published: 2006
Assessor/s: Vreven, E.
Reviewer/s: Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Programme)
Justification:
Barbus sexradiatus must be a rare species in Lake Victoria (or else confined to inaccessible habitats) because no specimens other than the unique holotype have been found and this despite intensive collecting between 1951–1957 (Greenwood 1962). More surveys are required.
