discussion
Remarks. Poorly distinguished from C. ceyhanense, both might be conspecific. Chondrostoma toros, C. ceyhanense, and C. kinzelbachi are all very closely related to C. regium and are difficult to distinguish. Future research may clarify whether they are better treated as distinct populations of C. regium.
