Lysidice is a genus of polychaete worms in the family Eunicidae.
The genus was originally described by Marie Jules César Savigny in 1818, describing three species from France and Spain, identified initially as L. galathina , L. olympia, and L. valentina.
It’s been assessed by various authors that the genus taxonomy needs to be revised, especially its older taxa and their synonymies and some specific species with morphological and molecular variability.
