Citharomangelia quadrilineata is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

This is a smooth, white shell with a fusiform-ovate shape and without spiral striae.

The four light fulvous lines crossing the body whorl seem to be a constant character.

The body whorl measures about ⅔ of the total length of the shell.

Kilburn had doubts about the generic position of this species, because of the low, continuous, cord-like axial ribs and the smooth wide intervals.
