China (Fenghsien), Korea (Incheon).</p> <p>Remarks. Shen (1955) first reported T. (E.) vermiculus from the coastal water of Fenghsien, Kiangsu Province. Later, Chen and Zhang (1965) redescribed this species from the Amoy. Until now, this species has been known as showing a restrictive distribution along the southern part of the East China Sea (Ohtsuka et al., 1992; Ohtsuka and Reid, 1998; Itoh et al., 2001). The discovery of this species in Korean waters would expand the range of the hitherto known biogeography.</p> <p>It is difficult to compare original specimen, because of poor description.</p> <p>Tortanus (Eutortanus) vermiculus is readily distinguished from other congeners by: anal somite and right caudal ramus of female with uneven dorsolateral process, and right exopod of leg 5 in male with long process along proximal inner margin.</p> <p>The amplified DNA was 631 bp in length. The partial CO1 sequence of T. (E.) vermiculus was determined for the first time and registered at GenBank (Accession no: JN605791).</p> <p>1 * Tortanus (Eutortanus) komachi Itoh, Ohtsuka and Sato, 2001 (Figs. 4-6)</p> <p>Tortanus (Eutortanus) komachi Itoh, Ohtsuka and Sato, 2001: 59, figs. 1-5.</p> <p>Material examined.

Korea (East Sea), Japan (south coast of Akita).</p> <p>Remarks. The Korean specimens coincide well with the</p> <p>Japanese specimen of the original description with the following two minor differences: (1) the fifth pedigerous somite of male produced posteriorly into blunt process in the Japanese specimen, but the present specimens display a slightly sharp process; (2) right caudal ramus is slightly longer than left one in the original specimen, but the caudal rami of the present Korean specimen are almost same in length.</p> <p>The amplified DNA was 614 bp in length.
