Alien Mollusca in the Levantine Sea: an update. Occurrence of Ervilia scaliola Issel, 1869 along the Levantine coast of Turkey

The present work updates the number of alien molluscs reported in the eastern Mediterranean since 2012 and brings the total to more than 100 species in the Levantine Turkish Coast. Ervilia scaliola Issel, 1869, widespread in the Red Sea, was collected in August 2013 from Tasucu Harbour, Levantine coast of Turkey. This is the first record of E. scaliola in the Mediterranean Sea. Although shipping appears to be the most probable vector of its introduction, Lessepsian migration cannot be ruled out as a pathway.
