Liotia olivacea Dall, 1918 Arene olivacea is a species of sea snail, a marine gastropod mollusk in the family Areneidae.

The color of the shell is very dark olivaceous, the prominent sculpture paler.

The minute nucleus is decorticated, but apparently smooth.

The spiral sculpture consists of, on the upper part of the body whorl, four strong elevated cords with wider, almost channeled interspaces.
