Two new species of the parasitic copepod genus Dissonus Wilson, 1906 are described: D. excavatus n. sp. from the gills of a labrid, Bodianus perditio, and a lutjanid, Macolor niger, collected off New Caledonia and Taiwan, and D. inaequalis n. sp. from a hemiscylliid elasmobranch, Chiloscyllium punctatum, collected off Sarawak (Malaysia) and the Philippines. Material of D. heronensis Kabata, 1966 is described from a balistid host, Pseudobalistes fuscus, off New Caledonia, and this constitutes a new host record for this parasite. D. manteri Kabata, 1966 was collected from four serranid host species off New Caledonia and from one of the same hosts off Taiwan. Two of the hosts from New Caledonia, Plectropomus laevis and Epinephelus cyanopodus, represent new host records. D. pastinum Deets & Dojiri, 1990 was recognised as a new synonym of D. nudiventris Kabata, 1966, so the total number of valid species is now twelve. Material from museum collections of D. nudiventris, D. similis Kabata, 1966 and D. spinifer Wilson, 1906 was re-examined and provided new information which is utilised in a key to all valid species of Dissonus.

The type-material of Dissonus inaequalis n. sp. was collected by Janine Caira under collecting permit No. UPE:40/2001/19SJ.924 from the Economic Planning Unit in Kuala Lumpur, and under research agreement No. SBC-RA-0050-JNC from the Sarawak Biodiversity Centre in Kuching. This work was supported in part with funds from US National Science Foundation (NSF) grants Nos DEB 0103640 and DEB 0542846. Field collections in Taiwan were supported in part by a grant from the Paramitas Foundation to JSH. CLL acknowledges support from projects NSC 91-2313-B-415-010 and NSC 94-2311-B-415-004 from the National Science of Council of Taiwan. The collaboration between GAB and SO was supported by a short term invitation fellowship from the Japan Society for the Promotion of Science. We are grateful to T Chad Walter for arranging the loan of the D. spinifer material from the USNM. We would like to thank Danny Tang for his careful review and for his suggested improvements to the manuscript. Prof. C. Chauvet (University of New Caledonia) kindly provided several of the groupers examined. Identification of all Bodianus specimens mentioned in this paper was kindly confirmed (from photographs) by Martin Gomon (Museum Victoria, Melbourne, Australia), who also provided comments and literature; identification of most other labrids was kindly confirmed (from photographs) by Ronald Fricke (Staatliches Museum für Naturkunde, Stuttgart, Germany). In New Caledonia, Julie Mounier, volunteer technician, and Charles Beaufrère, Audrey Guérin, Anaïs Guillou, Amandine Marie, Chloé Journo, Violette Justine, Eric Bureau, Maya Robert, Damien Hinsinger, Géraldine Colli, Lenaïg Hemery and Aude Sigura, all students, participated in the fishing operations and parasitological survey. Sam Tereua, Miguel Clarque and Napoléon Colombani, captains of the RV ‘Coris’ provided safe navigation. Angelo di Matteo (IRD) provided technical help. This paper is a contribution to the EU funded network of Excellence, EDIT.
