A new species of Acartia (Copepoda, Calanoida) from the Yellow Sea

چکیده
A new species (Acartia hongi) of Acartia (family Acartiidae) predominating in the Korean coastal waters of the Yellow Sea is described. This species closely resembles Acartia bifilosa, from which it can be easily distinguished by the co-occurrence of the following morphological characters: the absence of rostral filaments in both genders; the terminal spine on the female fifth leg toothed only on the inner side; the first exopodal segment of the male right fifth leg with a long seta; the distal segment of the male left fifth leg with a rod-like appendage. Its distribution was discussed in comparison with two sibling species, Acartia omorii and Acartia hudsonica.
