A new genus of cyclopoid copepod (Chondracanthidae) parasitic on halibut from California inshore waters.
Auchenochondria lobosa gen. et sp. n. was recovered from the oral cavity of the California halibut, Paralichthys californicus (Ayers), collected in Agua Hedionda Lagoon, Carlsbad, California. The new genus is closely related to Prochondracanthus Yamaguti 1939, and Rhynchochondria Ho 1967, but can be distinguished from them by the possession of cephalothoracic processes, a long neck, a 2-segmented abdomen, and a distinctly 6-segmented first antenna. Auchenochondria lobosa gen. et sp. n. is the only known species of chondracanthid in which the mandible of the male is equipped with more teeth on both the convex and concave surfaces than that of the female.
