Two new species of Copepoda (Crustacea) parasitic on marine fishes

Two new species of parasitic Copepoda (Crustacea) are described and illustrated. Paeon australis n. sp. (Sphyriidae) is the first member of its genus discovered in Australian waters. It is parasitic on Rhinobates batillum, an elasmobranch fish. The other species, Lateracanthus curtus n. sp., is a parasite of an unspecified Macrourus, a deep-water teleost, taken in the northwestern Atlantic. The systematics of the genus Lateracanthus are discussed. Lateracanthus macrurus is relegated to the status of a species inquirenda.
