Mangelia toreumata is a species of sea snail, a marine gastropod mollusc in the family Mangeliidae.

The spiral sculpture consists further of a strong simple thread revolving a short distance in front of the suture and forming the posterior margin of the fasciole.

There are also a dozen or more similar threads on the body whorl, extending from the periphery, where the interspaces are wide, to the siphonal canal, where they are narrow.

The base of the shell is subconic, slightly constricted for the siphonal canal.

The aperture is long, narrow and shorter than the spire (described as Mangilia toreumata)[2] This marine species occurs off Dominica and Guadeloupe.
