Description
The size of the shell varies between 5 mm and 15 mm, conical, and milky-white to pale cream, often translucent. Its surface features spiral cords and axial riblets, creating a grid-like texture. The protoconch is smooth, transitioning sharply to a teleoconch with up to four convex whorls. The narrow umbilicus (10% shell width) and thin outer lip distinguish it from relatives like A. meridiana, which has a broader umbilicus and weaker sculpture. The operculum is multispiral.[2][3]
Distribution
This marine species occurs off the coast of Japan, the Philippines and New Caledonia.
Etymology
Named for malacologist Makoto Kato; the genus combines Greek archi- ("primitive") and Minolia.
