Acrilla crebrilamellata is an extinct species of sea snail, a marine gastropod mollusk in the family Epitoniidae, the wentletraps.

The protoconch contains 2+1⁄2 whorls, the anterior one much contracted and ornamented with crowded oblique threadlets, the next is inflated and smooth ending in a bulbiform tip.

The latter consists of five, equidistant, equal, narrow, elevated, flat-edged lines.

The body whorl shows six spiral lines, the anterior one interrupting the convexity of the base.

[2] Fossils of this marine species have been found in Eocene strata in Victoria, Australia.
