A new species of caligid copepod, Anuretes justinei n. sp., is described from off New Caledonia. It is parasitic on the gill filaments of a haemulid fish, the yellowbanded sweetlips Plectorhinchus lineatus (Linnaeus). The new species is distinguished from its congeners by the combination of the following character states: (1) the fourth pedigerous somite is covered dorsally by the expanded free posterior margin of the cephalothorax; (2) a maxillary whip is present; (3) the relatively small genital complex is less than half the length of the cephalothorax; (4) leg 3 is armed with nine setae on the terminal exopodal segment and six setae on the terminal endopodal segment; and (5) leg 4 is long and slender with a setal armature of I, III twisted spines. The new species is an addition to the possibly monophyletic group of seven species that is characterised by the possession of a maxillary whip, all of which are found on haemulid hosts. The host-specificity of Anuretes is relatively high, its species being largely parasitic on reef-associated fishes, such as the families Haemulidae (eight species), Ephippidae (four species), Acanthuridae (four species) and Pomacanthidae (one species).
