Petroleuciscus
Petroleuciscus is a genus of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, Eurasian minnows and related fishes. It was usually included in Leuciscus until recently. This genus unites the Ponto-Caspian chubs and daces. Recent research has indicated that Petroleuciscus esfahani is probably a synonym of Alburnus doriae.
