The Indo-Pacific brachyuran Charybdis (Gonioinfradens) paucidentatus (A. Milne-Edwards, 1861) (Brachyura, Portunidae) in the Cyclades, Aegean Sea.

The occurrence of the alien Charybdis (Gonioinfradens) paucidentatus is reported from Santorini Island after repeated underwater surveys carried out in 2014-2015. The findings constitute the first record of an Indo-Pacific brachyuran in the south-central Aegean Sea, showing the successful expansion of this portunid recently introduced into the eastern Mediterranean Sea.
