Buchema interstrigata is a species of sea snail, a marine gastropod mollusk in the family Horaiclavidae.

Each of the longitudinal ribs may be said to be composed of four transverse nodules, and those on the body whorl are bifurcate from the middle downwards.

The lirae on the body whorl below the four principal ones are only slightly interrupted in the interstices between the ribs.

The aperture is whitish near the outer lip.
