Canaripusia zythochroa is a species of small sea snail, marine gastropod mollusk in the family Costellariidae, the ribbed miters.
The length of the shell attains 10 mm, its diameter 5 mm.
(Original description) The shell is oblong and acuminate, becoming somewhat attenuated toward the ends. The spire is spindle-shaped. The surface is ornamented with longitudinal ribs that become plicate at the suture; the ribs themselves are smooth, while the spaces between them are obscurely striated. The shell is yellowish-tawny in color and is marked by a white band. The columella bears five folds.
