Some New Zealand parasitic Copepoda of the family Pandaridae

The 723 copepods from 42 sharks captured in New Zealand waters belong to seven genera and 11 species of the family Pandaridae. Of these, Nesippus borealis (St. and Lüt.), recorded for the first time from a host fish, Dinemoura latifolia St. and Lüt., D. producta (Müller), Phyllothyreus cornutus (Milne‐Edwards), Pandarus cranchii Leach, and Echthrogaleus coleoptratus (Guérin) are widespread species. Pandarus bicolor Leach, Nesippus orientalis Heller, and Perissopus dentatus St. and Lüt. are each recorded from the Pacific for the second time, and the last two may be restricted to warmer waters. Demoleus latus Shiino and Echthrogaleus braccatus (Dana) are respectively recorded for the second and third time only and may be restricted to the western Pacific. Nesippus alatus Wilson, N. ornatus Thomsen and N. incisus Heegaard are probable synonyms of N. orientalis Heller; Dinemoura hamiltoni Thomson is a synonym of D. latifolia St. and Lüt. D. carcharodonti Thomson is a synonym of D. producta Dana and D. affinis Thomsen is probably a host form of this species. Pandarus armatus Heller may be a synonym of P. cranchii Leach and P. armatus as recorded by Thomson (1889) certainly belongs to the latter species; P. cranchii and P. satyrus Dana have not been satisfactorily separated in the literature.
