Paraguraleus emina is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

The colour of the shell is variable; sometimes entirely drab or buff, often with the protoconch and the subsutural space darker.

Both ribs and interspaces are crossed by sharp, minute, close, waved, spiral grooves.

The flat-topped interspaces of these grooves, four times their width, are again cross-cut by close minute furrows into oblong beads.

The aperture is narrow, three-fifths of the shell's length, fortified without by a broad but low incurving varix, which rises above the suture, enclosing a shallow sinus.
