Antiplanes litus is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae.

(Original description) The slender, white, acute shell has seven or eight moderately convex whorls separated by a very distinct suture.

There is also a semi-obsolete fine spiral striation covering the whole surface and somewhat stronger on the siphonal canal.

The anal sulcus is feeble, close to the suture hardly forming a fasciole.
