A bycatch surprise: <i>Scyllarus subarctus</i> Crosnier, 1970 (Decapoda: Achelata: Scyllaridae) in the Mediterranean Sea

Abstract Scyllarus Fabricius, 1775 includes nine species worldwide, three of which have been recorded from the Mediterranean Sea: S. arctus (Linnaeus, 1758), caparti Holthuis, 1952, and pygmaeus Bate, 1888. A specimen not ascribable to any previous was trawled in November 2020 unconsolidated substrates Gulf Naples, Italy. The sample subsequently identified through an integrative taxonomic approach as subarctus Crosnier, 1970, a originally described southern Angola (Eastern Atlantic Ocean) apparently expanding northward along Western Africa. It is possible that this taxon may already present but went overlooked or undetected. Results obtained molecular analyses underlined necessity extensive update supraspecific taxonomy scyllarids.
