Parapetulus spinosus, new species, was recovered from the gill arches of the samson fish Seriola hippos Gunther. The female of this species, although grossly different in its genital complex and abdomen, is otherwise virtually identical with Caligus spinosus Yamaguti, which was found on the same host. Also, the male of the new species appears to be identical in every detail with the males described from C. spinosus. The similarities are explained by divergent evolution on one host species. A proposal to relagate Caligus kurochkini Kazatchenko to the genus Parapetulus is given, bringing the Australian records of the genus to three species. In December of 1983 a study was initiated in the Coffs Harbour area on the Australian east coast of the ectoparasite fauna of the samson fish (Seriola hippos). Two copepod species were recorded, and although they belong to different genera of the same family (Caligidae), they are remarkably similar in most morphological characters. Fish were caught by rod and reel, from Coffs Harbour, New South Wales, They were pithed, their heads cut off and placed in 10% formalin. The external surface, mouth cavity, nares, gills and gill arches as well as sediment from fish samples were examined by Dr. Chris Donovan. Copepods were excised and washed in sea water prior to fixation in 70% alcohol. Specimens were cleared and dissected in lactic acid. Measurements of male and female copepods are based on ten specimens each. Measurements are given in micrometers (J-lm) as mean (range), length width. Drawings were made using a camera Iucida. Parapetulus spinosus sp. nov. Material examined. Holotype female (222993), allotype male (222994), 5 female paratypes (222995) and 2 male paratypes (222996) deposited in the National Museum of Natural History, Smithsonian Institution; 3 female paratypes (1985. 341-343) and 3 male paratypes (1985. 344-346) deposited in the British Museum of Natural History.
