† Glyphostoma moinica A.A. Olsson, 1922 Lioglyphostoma moinica is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.

(Original description) The small, solid shell has a coarse, tuberculate, subreticulate sculpture and a thickened, enlarged outer lip.

The sculpture consists of about 14 narrow ribs continuous from the siphonal canal to the upper suture and crossed by even, spiral cords.

The aperture is elliptical with a large expanded outer lip, smooth within and a deep, anal sinus at its upper end.

[2] Fossils have been found in Pliocene strata of the Costa Rica and Jamaica age range: 3.6 to 2.588 Ma.
