Cheilobarbus, commonly known as sawfins, is a small genus of freshwater ray-finned fishes belonging to the family Cyprinidae, the family which includes the carps, barbs and related fishes. The fishes in this genus are endemic to the Western Cape of South Africa.

Taxonomy

Cheilobarbus was first proposed as a taxon, a monotypic subgenus of the genus Barbus, by the Scottish military surgeon and zoologist Andrew Smith in 1841 [1] when he described Barbus (Cheilobarbus) capensis from the Olifants River on the western coast of South Africa. [2] This genus is included in the subfamily Smiliogastrinae within the family Cyprinidae. [3]

Etymology

Cheilobarbus combines cheilos, meaning "lip", with the genus name Barbus, Smith described B. capensis as having "full and firm" lips. [4]

Species

Cheilobarbus contains the following species: [2]

Both species are tetraploid, like Pseudobarbus redfins, from which they were separated. [5]

Characteristics

Cheilobarbus fishes are among the largest of the South African barb species and reach standard lengths greater than 15 cm (5.9 in). They have a relatively longer snout than related genera with an elongated lacrimal bone. They have an inferior mouth which has large, firm lips and there are two pairs of barbels Adults show a reddening on the crown and on a scale row above the pectoral fins during the spawning season. The dorsal fin is over or a little to the rear of the pelvic fins. The last unbranched dorsal fin ray is slightly or clearly serratde along its posterior margin, and this is followed by eight branched rays. There are three unbranched and five or six branched fin rays in the anal fin. [5]

Distribution and habitat

Cheilobarbus fishes are endmeic to the Western Cape, the Cape whitefish is found in the Breede and Berg drainages [6] and the sawfin is endmeic to the Olifants River system. [7] These fishes prefer deeper parts of large rivers as adults, including impoundments. [6] [7] Cheilobarbus species reproduce in the summer and form large groups that spawn together on rocky bottoms. [8] [9]

Barbus is a genus of ray-finned fish in the family Cyprinidae. The type species of Barbus is the common barbel, first described as Cyprinus barbus and now named Barbus barbus. Barbus is the namesake genus of the subfamily Barbinae, but given their relationships, that taxon is better included in the Cyprininae at least for the largest part.

The Olifants River is a river in the northwestern area of the Western Cape Province of South Africa. The upper and main catchment area of the Olifants river is around Ceres and the Cederberg mountains. The Clanwilliam and Bulshoek dams are located on the river and provide water for the towns and farms along the watercourse. The river is approximately 285 km long with a catchment area of 46,220 km2. It flows into the Atlantic Ocean at Papendorp, 250 km north of Cape Town.
