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

(Original description) The solid, white shell has an olivaceous periostracum.

The spire of the holotype is badly eroded, short, indicating a total of five whorls exclusive of the protoconch.

The anal fasciole is narrow, constricted and separated from the suture by an obscure ridge.

In front of the fasciole is an undulated rounded ridge from which extend obliquely protractive obscure riblets more or less obsolete on the body whorl, probably stronger and more distinct on the spire when not eroded.
