Abstract
Three species of parasitic cyclopoid copepods are reported from the Shiner Surfperch, Cymatogaster aggregata Gibbons, collected from Anaheim Bay and Huntington Harbor, California. One of the copepods, Holobomoloclhus embiotocae, new species, of the family Bomolochidae inhabits the nasal cavity of the shiner perch. The other two copepods, Bomoloclus cuneatus Eraser and Ergasilus lizae Kroyer, are reported as new host and locality records.
