Kuroshiodaphne supracancellata is a species of sea snail, a marine gastropod mollusc in the family Raphitomidae.
The strong shell is elongately-fusiform, with long, slender spire and a short siphonal canal.
The subsequent whorls are slightly convex, separated by a linear, indistinct suture, bordered by a narrow excavation.
These lirae produce a cancellation on the upper 4 post-nuclear whorls (hence the name); moreover there are numerous finer spiral lines between the principal ones, making the whole shell spirally striated, crossed by more or less conspicuous growth-striae, strongly incised at intervals, closer on last part of the body whorl, making the principal lirae nearly beaded.
The columellar margin is slightly concave above, then nearly straight, with a thin layer of enamel, which is faintly multiplicate.
