Clanculus rubicundus is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.[1]

Description

The height of the shell attains 6 mm, its diameter about the same. The narrowly umbilicated, rubicund shell has a globose-conic shape. Its whorls are rounded, separated by canaliculate sutures and elegantly granose-cingulate. The umbilicus shows a white, crenate margin. The columella is thick, twisted, incised above, and passes into a thick tooth below. The lip is thickened, sulcate within, and splendidly pearly.

This is a beautiful species, allied to Clanculus corallinus (Gmelin, 1791), but much more slender. The elevated riblets are densely crenate and the interstices canaliculate. The spiral riblets on the penultimate whorl number four, on the last whorl inclusive of the base of the shell, 12 to 14. The color is uniform ruddy or scarlet, variegated with white in the umbilical region.[1]

Distribution

This marine species occurs in the Pacific Ocean off Fiji in the Viti Levu Group.
