Leiocithara apollinea is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

This white shell is a scalate Leiocithara .It has an ovate fusiform shape and contains 5 whorls.

It is principally conspicuous for its thickened longitudinal ribs, 9–10 in number on the body whorl.

One spiral keel alone, a little below the sutures, crosses the ribs at right angles, and at the point of junction bears a beaded point.

[2] This species occurs in the Gulf of Oman.
