Summary:
The poecilostome family Taeniacanthidae, copepods parasitic on marine fishes and sea urchins, currently consists of 14 genera and 91 species (including 14 new species described in this revision). Three genera (Clavisodalis, Echinirus, and Echinosocius) live in the esophagi of sea urchins. Eleven genera (the type genus Taeniacanthus, Anchistrotos, Cirracanthus, Irodes, Metataeniacanthus, Nudisodalis, Phagus, Pseudotaeniacanthus, Scolecicara, Taeniacanthodes, and Taeniastrotos) are parasites of marine fishes. Parataeniacanthus is placed in synonomy with Taeniacanthus, and two new genera (Cirracanthus and Nudisodalis) are described. Keys are provided for all taeniacanthid genera and species parasitic on fishes (keys to the species of the genera associated with echinoids are found elsewhere).A descriptive account of the external morphology of this family is given. The detailed morphology of the general habitus, rostral area, first and second antennae, postantennal process, oral appendages, and legs is discussed in relation to their taxonomic significance.The first record of aggregative behavior of a poecilostome copepod is reported. Individuals of Taeniacanthodes gracilis form a cluster on the fins of their host, Paralichthys squamilentus. The individuals are arranged in single-file or a staggered pattern.Taeniacanthids exhibit a high degree of host specificity at both the generic and specific levels. Host-parasite relationships between taeniacanthids and tetraodontiform fishes are discussed.The known zoogeographic distribution suggests that the greatest diversity in genera and species of taeniacanthids occurs in the Indo-West Pacific. Taeniacanthus is the most ubiquitous genus, but more extensive collections for taeniacanthids must be made before conclusions on the distribution of these copepods can be reached.Phylogenetic relationships within the bomolochiform complex, comprised of the Bomolochidae, Taeniacanthidae, and Tuccidae, are discussed. The Tuccidae is considered the most derived family. The Bomolochidae and Taeniacanthidae have a mosaic of plesiomorphic and apomorphic characters. A phylogenetic analysis must be done before conclusions can be made concerning familial relationships. The relationship of the Telsidae to the complex is discussed.Host-parasite and parasite-host lists are included. Scanning electron micrographs of selected species are provided to augment the line drawings.
