Filodrillia is a genus of sea snails, marine gastropod mollusks in the family Borsoniidae, the cone snails and their allies.


Filodrillia is a genus from deep water which resembles Etrema in the form of the sinus, but not of the protoconch, but differs in the thin slender shell, turreted whorls, absence of ribs and varix. The spiral sculpture predominates.


This marine genus is endemic to Australia and occurs off New South Wales, South Australia, Tasmania and Victoria.
