Scientific Name: Barbus toppini
Species Authority: Boulenger, 1916
Common Name/s:
English – East Coast 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this paper the term ‘Barbus’ for the cyprinid fish species which were previously considered as Barbus (Seegers et al., unpublished).The status of the northern Ewaso Nyiro population is uncertain (Seegers et al., unpublished).
