Naricolax insolitusn. sp., a bomolochid copepod (Poecilostomatoida) parasitic in the nasal cavities of silver pomfret Pampus argenteusoff Taiwan

A new species of bomolochid copepod (Poecilostomatoida), Naricolax insolitusn. sp., parasitic in the nasal cavities of the silver pomfret Pampus argenteus(Euphrasen) from the Strait of Taiwan is described. The new species is distinguished from its only known congener, N. atypicusHo, Do & Kasahara, 1983, by possessing the following four apomorphic features: (1) a complex outgrowth on the egg-sac attachment area; (2) a bent egg-sac; (3) a sharp hook (modified seta V) on the caudal ramus; and (4) an armature of II,I,4 (instead of II,I,5) on the terminal segment of leg 4 exopod. This is the first record of parasitic copepod from the nasal cavities of the silver pomfret.
