Remarks. Ervilia scaliola was first recorded from Turkey based on material collected in 2013 by Zenetos and Ovalis (2014) who correctly described the complex taxonomic status of this genus in the Indo-Pacific. We here record the species from Israel for the first time. The complete shell from Ashqelon (Figure 42 ) is very fresh, and thus probably originates from an extant population. Figure 42.
