Abstract
    Gemfishes of the genus Rexea from the New Caledonia Exclusive Economic Zone (EEZ) are reviewed based on fresh and preserved specimens. Three species are recognized: Rexea antefurcata Parin, 1989, confirming recent records (previously also recorded as R. prometheoides), distinguished by the presence of small scales on the caudal peduncle and extending anteriorly along the edges of the lower lateral line, lateral line branching below the 4th-5th dorsal fin spines, a long pectoral fin, and dusky colour of spinous dorsal fin membrane and (in adults) pectoral fin; R. bengalensis (Alcock, 1894), first record, distinguished by its small maximum size, lateral line branching below the 5th-6th dorsal fin spines, long pectoral fin, and naked body (except lateral line); and R. alisae sp. nov., endemic, distinguished by 3-4 dorsal finlets and 4 anal finlets, lateral line branching below the 6th to 7th dorsal fin spines, posterior extent of the upper lateral line, its naked body (except lateral line), and coloration. A key to New Caledonian gemfishes {Rexea spp., Rexichthys johnpaxtoni and Promethichthys prometheus) is provided.
