Description

The shell attains a height of 2 mm. The shell has an ovate, depressed shape. The spire is nearly plane. The 2½ whorls are plane. The body whorl is radiately striate above the carina (more strongly at the sutures). It is ornamented below the carina with elevated, transverse cinguli. The base has elevated concentric lines with its interstices cancellated. The aperture is oblique. The inner lip recedes.

This species hase a foramen instead of a fissure. It is characterized by a flattened spire and three prominent keels on the last whorl below the carinate periphery. It most nearly resembles Sukashitrochus dorbignyi (Audouin, 1826) but there are three keels besides the fissural carina.[3]

Distribution

This marine species occurs off Japan.
