In the Mediterranean western basin, R. cemiculus is unknown at present of the European shore but is rather frequent of southern areas; conversely, the species occurs throughout the eastern basin. Two large specimens recorded for the frst time in İzmir Bay, northern Aegean Sea, are reported and described in this note. Tese fndings constitute the northernmost records of R. cemiculus in both the Aegean Sea and the Mediterranean Sea, and they signifcantly extend the species’ distribution known to date.Blackchin guitarfsh, Rhinobatos cemiculus, is rather abundantly captured in the eastern tropical Atlantic, especially of Senegal and Mauritania.
