Affiliation: For the 19 species recorded from Korea, we compared the original descriptions of the species with their corresponding descriptions from Korean forms. Finally, we revised the taxonomic list of Korean Triphoridae species. The classification system of species list followed Bouchet and Rocroi (2005). In addition, one individual of M. rubra was collected in the intertidal zone of Jeju Island and identified as a new record from Korean waters. Shell morphology of the specimen was examined and compared with other Korean triphorid species using a stereoscopic microscope (Leica M205C, Wetzlar, Germany). The specimen examined was deposited in the National Institute of Biological Resources (NIBR), Incheon, Korea (VQUMIV0000001636).

Abstract: The family Triphoridae Gray, 1847 is a group of marine microgastropods characterized by sinistral (left-coiled) shells except for the subfamily Metaciinae, which has dextral shell coiling. We report a new record of Mastonia rubra (Hinds, 1843) collected from the intertidal zone from Jeju Island, Korea and revise species list for Korean Triphoridae species. Mastonia rubra is distinguished from Inforis fusiformis (Kosuge, 1961) by the purple color of the first and second whorls of the teleoconch, whereas they are light colored and nearly white corresponding whorls in I. fusiformis. Including this new record, the Korean Triphoridae comprises 20 species from 15 genera.
