Microdrillia commentica is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.

(Original description) The small, solid shell has a narrowly fusiform shape.

The first three are small and smooth, the next ones with a dozen prominent curved radial ribs.

The fasciole is sculptured by transverse crescentic threads becoming weaker on the later whorls.
