Bela simplicata is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.[1]

Description

The length of the shell varies between 5 mm and 8 mm, its diameter between 2 mm and 3 mm.

It shows a close resemblance to Oenopota pyramidalis (Strøm, 1788) (synonym: Bela pyramidalis), but it is smaller and shorter. The spire is less acuminate. The body whorl is higher. The aperture is not as high. The shell contains less longitudinal ribs, which become obsolete at the body whorl where they are replaced by plicae.[2]

This species occurs in the Bay of Biscay off France ar depths between 650 m and 1410 m.
