Luciobarbus ( Syn .: Messinobarbus Bianco, 1998 ) is a genus of carp fish (Cyprinidae). The genus occurs in North Africa ( Tunisia , Algeria and Morocco ), on the Iberian Peninsula , in Asia Minor , in the Caucasus and its northern foothills, in Mesopotamia , in western Iran and in the catchment area of the Caspian Sea and the Aral Sea . It wasset upby Johann Jakob Heckel as early as 1843, but for a long time it was not recognized and its species were assigned to the genus Barbus .

features

Luciobarbus species are 23 cm to 2.30 meters long. They differ from the Barbus species, among other things, in the shape of the lower lip, the middle section of which in Luciobarbus has no papillae, while in Barbus it is completely covered with papillae. In addition, the number of teeth in the main row of the pharyngealia is different: four in Luciobarbus , five in Barbus .

Other features of the genus include the high mean outgrowth and the broad base plate of the Urohyale, a tendon ossification in the skull, the broad fourth and fifth infraorbitalia (bones around the eyes), the front edge of the cleithrum that is perpendicular to the lower thigh and its long and narrow upper leg. In addition, the convex anterior edge of the gill cover, the broad ethmoid , the small vor vomer , which has a long and sharp point, and the tendency that in old fish the number of gullet teeth decreases and the fourth in the outer row becomes particularly strong. You also get crescent-shaped chewing surfaces. The basal plate of the pharyngealia is elongated downwards.

evolution

The genera Barbus and Luciobarbus separated in the late Miocene about 8 million years ago. The split followed the successive plate tectonic movements that took place in the southern Mediterranean region. In the Pliocene, about 2 million years ago, the establishment of today's river systems resulted in rapid speciation in both genera.
