Acinodrillia is a genus of sea snails, marine gastropod mollusks in the family Drilliidae.
Description The length of the claviform shell varies between 7mm and 12 mm. The spiral sculpture of the shell shows sharply incised grooves, carving through the axial ribs into distinct nodules or granules. These axial ribs disappear below the suture. Contrary to the species in Drillia, the anal sinus is not spout-like. Contrary to Agladrillia, the outer lip is not pinched in toward the base of the shell. The body whorl shows a dorsal varix (a subcylíndrical protrusion). The wide siphonal canal is unnotched. Kilburn, R. N. "Turridae (Mollusca: Gastropoda) of southern Africa and Mozambique. Part 4.
