Abstract / Introduction / Summary:
A living pyramidellid mollusk belonging to the genus Ondina de Folin, 1870 was collected from underside of a beach boulder in Iorigawa inlet, Kadogawa town, Miyazaki prefecture and another shell specimen was sieved out from the rivermouth bottom sediment of the Yakukachi, Amami island, Kagoshima prefecture. These specimens were thought to belong to a single undescribed species very near to O. michaelae Cachia & Mifsud, 2015, but differ from the latter in having a labral margin in the grown shell. The living animal was also photographed and the soft body part was recorded. A dead shell of another congeneric species was also collected from rocky shore sediment of Miyazaki city.
