Labeobarbus intermedius
Labeobarbus intermedius is an East African ray-finned fish species in the family Cyprinidae. Like the closely related yellowfish, it is hexaploid. A large species, the maximum recorded standard length is nearly . This species has a subspecies named "Labeobarbus intermedius intermedius". Systematics and taxonomy. The year of its first description – as "Barbus intermedius" – was for some time erroneously reported as 1837. "L. intermedius" was still placed by most modern authors in the "wastebin genus" "Barbus" by default, and the IUCN still does so until a thorough taxonomic revision of the African "barbs" is published. However, the species is  increasingly being restored to related yellowfish genus "Labeobarbus", which seems a much more appropriate placement. It is a close relative of "Labeobarbus bynni", another African "barb". No subspecies are recognized at present. The population from the Barino River basin invalidly described as "L. i. australis" is identical with the earlier-named "gregorii", but probably not sufficiently distinct from its conspecifics to consider it a separate taxon. The same holds true for the supposed subspecies "leptosoma" and "microstoma". Important junior synonyms of this species are: Its close relatives "L. brevicauda", "L. gorgorensis" and "L. johnstonii" (under the name "latirostris"), and even  the rather distinct "Barbus eurystomus", were for some time placed in ""B." intermedius" as subspecies too. But are considered distinct species today. "B. procatopus" is sometimes believed to refer to the present species, but it is actually a junior synonym of the ripon barbel ("B. altianalis"). Distribution and ecology. This freshwater fish is found in Kenya, Tanzania, Uganda and southern Ethiopia. Its natural habitats are the Kerio, Suguta, Turkwel and northern Ewaso Ng'iro Rivers and their tributaries, as well as Lake Baringo, Bogoria and Turkana and their associated rivers. The records from the Tana River region are based on mislabelled  specimens, while the supposed records from the Mara River and Lake Victoria appear to be based on misidentifications of the Ripon Barbel. Little is known about its population and ecology, but given its wide range and lack of readily apparent threats, it is not considered a threatened species by the IUCN.
