Two new species of taeniacanthid copepods (Poecilostomatoida) parasitic on marine fishes of Taiwan

Two new species of copepods (Poecilostomatoida Taeniacanthidae) parasitic on fishes of Taiwan are reported. They are: Irodes parupenei n. sp. from Parupeneus spilurus (Bleeker) and P. multifasciatus (Quoy & Gaimard), and Taeniacanthus spiniferus n. sp. from Acanthocepola limbata Valenciennes. I. parupenei is characteristic in having nine (instead of eight) elements on the terminal segment of leg 2 exopod, a spiniform element (instead of a long, plumose seta) on the medial margin of the proximal segment of leg 4 endopod, and thee spines and one long, naked seta (rather than four short setae) on the slender (rather than spatula-like), terminal segment of leg 5. T. spiniferus is distinguished from its 38 congeners in carrying a pair of sharp tines in the ventral area of the rostrum.
