Mangilia acrocarinata W. H. Dall, 1927 Lioglyphostoma acrocarinatum is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.

The fasciole extends between the suture and the shoulder of the whorl, flattish and smooth except for incremental lines.

The axial sculpture consists of (on the body whorl 10) extremely short ribs which appear chiefly as pointed nodules on a peripheral minute keel and again as faint pustules on a thread near the margin of the base; with wider interspaces.

tTe general surface of the shell is polished with a waxy luster.

[2] This marine species occurs in the Atlantic Ocean off Georgia to Florida, USA.
