Abstract

Two cymothoid isopods, Rocinela niponia Richradson, 1909 and Bopyrus squillarum Latreille, 1802, are first reported from Korean waters. Rocinela niponia can be distinguished from its congeners by the following characteristics: the rostral point is round; the eyes are separated from each other; and each pereopods 1-3 has the propodal blade bearing eight robust setae. Bopyrus squillarum is distinguishable from its related species by the following characteristics: the head is separated from pereonite 1, but partially fused on the lateral margins; the first pleonite on the short side is much smaller than other segments; and it is parasitic on the branchial chamber of Palaemon serrifer. Detailed descriptions and figures of these two species are provided in this paper.
