It is often included in B. cyclolepis. More recently, it has been hypothesized to be a natural hybrid that originated from a common barbel (B. barbus) female mating with a Carpathian barbel (B. carpathicus) male. Nevertheless, the populations do not seem to represent first-generation hybrids. It is recorded or suspected from Poland, Slovakia and Ukraine.
