Sukashitrochus carinatus

Sukashitrochus carinatus is a species of small sea snail, a marine gastropod mollusk or micromollusk in the family Scissurellidae, the little slit snails.

The body whorl is radiately striate above the carina (more strongly at the sutures).

The base has elevated concentric lines with its interstices cancellated.

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.
