New host and geographical records of siphonostomatoid copepods associated with elasmobranchs off the KwaZulu-Natal coast, South Africa.

The Siphonostomatoida (Copepoda) consists of 40 families comprised mainly of symbiotic members. Representatives of 12 families occur in symbiosis with elasmobranchs. Only eight families, 19 genera and 35 species have been reported from 37 elasmobranchs off the coast of South Africa. Elasmobranchs caught in the nets of the Natal Sharks Board and by fishermen of the Meer-en-See Boat Club, KwaZulu-Natal Province were examined for symbiotic siphonostomatoids. Additional to previous families reported, members of Cecropidae and Sphyriidae are being reported. Genera for the first time reported from South African waters include Entepherus, Carnifossorius, Eudactylina, Eudactylinodes, Kroeyerina, Pannosus, Phyllothyreus and Paeon. Therefore, currently ten siphonostomatoid families are reported from 49 species of elasmobranchs including 27 genera and 58 species.
