Caligus ignotus n. sp. (Copepoda: Caligidae) parasitic on Poey's scabbardfish Evoxymetopon poeyi (Günther) off Taiwan.
A new species of caligid copepod, Caligus ignotus n. sp., is described from Poey's scabbardfish Evoxymetopon poeyi (Günther) (Trichiuridae) caught off the southeast coast of Taiwan. The parasite was found in the gill-cavity of this benthopelagic fish. The new species is distinguished from its congeners mainly in the structure of the female genital complex (shaped like a guitar) and abdomen (with three sections and gradually broadening from anterior to posterior). This is the first report of a copepod parasite from Poey's scabbardfish.
