Material examined. MBM 300739 (1 articutate shell), Jiaozhou Bay, Station C-5 (36°6’N, 120°18’E), Kexue II R/ V, on June 25th, 1985; MBM265366 (1 articutate shell), Liaodong Bay, Station B66A, in mud, 26m, Kexue I R/V, on July 1st, 1988.

Distribution and habitat. Recent. Bohai Sea, Jianzhou Bay, China; Japan; Korea. Sandy mud bottom 5– 50 m. Life habitat unclear, possibly commensal with echiurid worms, such as in the case of Paramya subovata ( Jenner & McCrary 1969; Henry 1976) and the third species of this genus P. africana (see Cosel 1995).

Type locality. Yobuko, Saga Prefecture, Kyushu.

Diagnosis. Length to 10 mm; gaping anteriorly and posteriorly; boundary between posterior area and posterocentral shell obtusely convex; umbo small; sculpture of coarse growth commarginal lines, with minute granulations, more obvious on the ventral margin; chondrophores of similar size; pallial sinus shallow, does not exceed further ventral than posterior adductor scar; pallial line thin orobscure.
