Reconfirming the hybrid origin and generic status of the Iberian cyprinid complex Squalius alburnoides.

The recent allocation of the cyprinid complex Squalius alburnoides to the genus Iberocypris in the Handbook of European Freshwater Fishes is refuted by confirming evidence of a close relationship with the genus Squalius. Squalius alburnoides is here defined as a complex based on the existence of a hybrid form with distinct genome combinations and ploidies and of a reconstituted nuclear non-hybrid male form also with hybrid origin.
