title: The first chondracanthid (Copepoda: Cyclopoida) reported from cultured finfish, with a revised key to the species of Chondracanthus.
abstract: A new species of the Chondracanthidae (Copepoda: Cyclopoida), Chondracanthus goldsmidi, is described based on material collected from the nasobranchial region of striped trumpeter (Latris lineata [Forster]) cultured at the Tasmanian Aqua-culture and Fisheries Institute, Marine Research Laboratories, Australia. This represents the first report of a chondracanthid copepod infecting cultured finfish and the first metazoan parasite from cultured striped trumpeter. Chondracanthus goldsmidi n. sp. can be distinguished from its female congeners by the absence of lateral processes on the head and the presence of 3 pairs of lateral trunk outgrowths, 3 middorsal body outgrowths (of which the first 2 are rounded), a small and subcylindrical antennule, and unornamented legs 1 and 2. A revised key to the 39 valid species of Chondracanthus is provided.
