Barbus sp. 'Nzoia 2'

'Barbus'' sp. 'Nzoia 2 is an undescribed but distinct ray-finned fish species in the family Cyprinidae. It was first reported in 1999. A small African barb, it is provisionally assigned to the genus Barbus, but probably belongs – like similar species – in another genus.

It is apparently endemic to Kenya. The only places where it has been found to date are in the Nzoia River drainage basin of the Lake Victoria region; it might occur elsewhere though. It may be a threatened species, but too little is known about its distribution, population size and taxonomy to judge its status with a higher level of certainty. Therefore, it is classified as Data Deficient by the IUCN, but this will change when this fish becomes better known.
