ABSTRACT A new genus and species of copepod, Norkus cladocephalus (Siphonostomatoida: Sphyriidae), is described from specimens collected from the hemibranchs of the shovelnose guitarfish Rhinobatos productus (Ayres) from southern California. The new genus is distinguished from confamilial genera by the presence of (1) an elaborately branched holdfast on the cephalothorax, (2) an expanded collar on the anterior end of the neck, (3) a dorsoventrally flattened discoid trunk, and (4) simple, cylindrical posterior processes (modified caudal rami). A phylogenetic analysis of the Sphyriidae, using the lernaeopodid genus Ommatokoita as the outgroup, was conducted. A single parasite cladogram and host summary and ecological summary cladograms are presented and discussed.
