Bomolochid copepods (Crustacea: Copepoda: Bomolochidae) parasitizing immigrant and native barracuda (Actinopterygii: Sphyraenidae) caught off the Egyptian Mediterranean coast

Two species of parasitic copepods (Family Bomolochidae) are reported from two species of barracudas (Family Sphyraenidae) caught in Mediterranean waters off Alexandria, Egypt. Nothobomolochus denticulatus (Bassett- Smith, 1898) is recorded on yellowstripe barracuda, Sphyraena chrysotaenia Klunzinger, which is an immigrant from the Red Sea that has become established in the Mediterranean. This is a new geographical record of N. denticulatus from the Mediterranean and the female of N. denticulatus is redescribed in detail. Bomolochus unicirrus Brian, 1902 is recorded on European barracuda, Sphyraena sphyraena (L.), a fish native to the Mediterranean, and slight differences between this material and material from the Atlantic, off Mauritania, are noted.
