Laetifautor rubropunctatus is a species of sea snail, a marine gastropod mollusk in the family Calliostomatidae.

Tryon rather considers it pale fleshy pink, with dark red dots in the interstices between the oblique costae and the transverse or spiral ridges.

The points of intersection of these spiral ridges and the oblique costae are produced into quite acute nodules or prickles.

The base of the shell is almost flat, ornamented with about six concentric lirae, which are more or less granulous, with the interstices exhibiting strong lines of growth and translucent nacre.

The color closely approaches the rest of the surface, varied with brown dots both upon and between the granules.
