Leiocithara infulata is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.
(Original description) The small shell is very solid, regularly biconical and sharply angled at the shoulder.
Sculpture: on the body- whorl are eight widely spaced thick and prominent vertical ribs radiating from the suture, and vanishing on the base.
On the antepenultimate whorl the spiral cord degenerates, and the radials are closer, rounder, and more oblique.
The aperture is narrow, protected by a heavy outstanding varix, anteriorly with a semicircular excavation, followed by a tubercle on either side.
