Fusipagoda sapia is a species of sea snail, a marine gastropod mollusc in the family Retimohniidae, the true whelks and the like.
[1] (Original description as Colus (Aulacofusus) sapius) The small, thin shell measures 22 mm.
The whorl in front of it is flattened and without spiral sculpture for a short distance.
The spiral sculpture consists of (on the penultimate whorl about eight) strong squarish ribs with subequal rather deep, channeled interspaces.
Both are slightly wrinkled by the incremental lines and become obsolete on the siphonal canal.
