Westward range expansion of the Indo-Pacific nakedband gaper Champsodon nudivittis (Ogilby, 1895) in Saronikos Gulf, Greece

The Indo-West Pacific nakedband gaper, Champsodon nudivittis, was recorded for the first time in Saronikos Gulf (central Aegean Sea, Greece) on the basis of a single specimen collected by bottom trawl on 13 October 2017 at 89 m mean depth. DNA barcoding was used as a complementary tool to standard taxonomic features description for species identification. The present record corresponds to the westernmost expansion of this Lessepsian migrant, whose transition from the Levantine basin to the west was clearly associated with a deceleration in dispersal rate.
