The southernmost record of Felimida elegantula (Philippi, 1844) (Gastropoda: Nudibranchia)

ABSTRACT: The southernmost record of the Mediterranean nudibranch Felimida elegantula (Philippi, 1844) is reported here. A single specimen, with a colour pattern that hampered an easy morphological identification, was collected at the Kerkennah Islands (Tunisia). DNA-barcoding analysis (with the cytochrome c oxidase subunit I genetic marker) unambiguously confirmed its identification, and radular and anatomical features conformed with those previously described. With this record, the chromatic polymorphism of F. elegantula is demonstrated to be extremely large and the known range of the species is extended to the African coast of Tunisia. © 2016, Senckenberg Gesellschaft für Naturforschung and Springer-Verlag Berlin Heidelberg
