Further record of <i>Pisionella hancocki</i> Hartman, 1939 (Annelida: Polychaeta: Pisionidae) in Japan with additional information on some morphological characters.
Pisionella hancocki Hartman, 1939 was recorded from a sandy beach of Sakishima Isls., the Ryukyus, south-western Japan. Concerning the geographical distribution, this is the first record in the subtropical region of the west coast of the North Pacific. Close examination of the material, inclusive of SEM observation, has revealed some detailed morphological characters of prostomial antenna, acicula, and setae, all of which are confirmed for the specimens from off the Tango Peninsula, the Sea of Japan.
