Asthelys munda is a species of sea snail, a marine gastropod mollusk in the family Seguenziidae.

On the base of the shell there are about eleven fine spirals, within which is a strong furrow, and a projecting, crenulated, or ropelike thread forming the edge of the umbilicus.

The colour of the shell is opalescent, from the underlying nacre shining through the polished, thin, translucent calcareous layer of the surface.

It is sharply angled at the periphery, slightly arched across the base, apparently nicked at the point of the columella.

The inner lip is arched, strengthened by a thin pad, reverted on the umbilicus so as to leave a groove behind it, with a slight tooth in front.
