Six species of the ostracod families Loxoconchidae and Cushmanideidae from South Korea

Three <i>Loxoconcha</i> Sars, 1866 (<i>L. bizenensis</i> Okubo, 1980, <i>L. japonica </i>Ishizaki, 1968, and<i> L. tosaensis</i> Ishizaki, 1968), one <i>Loxocorniculum</i> Benson and Coleman, 1963 (<i>Lc. mutsuense</i> Ishizaki, 1971), and two <i>Pontocythere</i> Dubowsky, 1939 (<i>P. miurensis</i> (Hanai, 1959), and <i>P. xiphoidea</i> Nakao and Tsukagoshi, 2002) species are briefly redescribed and illustrated. Soft part morphology of<i> L. tosaensis</i> are described and illustrated here for the first time, since this species was known only by the shell morphology. A key to all living <i>Loxoconcha</i> and <i>Loxocorniculum</i> species from East Asia is suggested to facilitate subsequent identification, along with the lists to all East Asian species of the three genera.
