Otukaia is a genus of medium-sized sea snails, marine gastropod molluscs in the family Calliostomatidae, the top shells. Otukaia has long been considered a subspecies of Calliostoma and is still treated as such by many authorities.
They are characterized by their relatively large, silky-white, thin shell. They lack an umbilicus. Their spiral whorls are flat to slightly convex. The first three spiral cords can show some sculpture that may persist on later whorls. They have a rachidian radula. They can be found world-wide in deep water.
