We report a new record of Myurella nebulosa (Sowerby, 1825) collected by SCUBA diving from sandy bottom of subtidal zone in Jeju Island in Korea. The specimen of M. nebulosa is distinguished from its congeners by having slightly plump shell, high spire, distinctive subsutural band, deep axial ribs, numerous and shallow spiral ribs, ivory in color. In this report, we provided a brief morphological description and photographs of M. nebulosa. An unrooted phylogenetic tree for mitochondrial cox1 sequences using NJ analysis found Korean M. nebulosa sample was clustered with its conspecific sequences, but clearly separated from M. columellaris that is not easy to distinguishable based on external shell morphology alone.
