Filodrillia ludbrookae is an extinct species of sea snail, a marine gastropod mollusc, in the family Borsoniidae. Fossils of the species date to middle Miocene strata of the St Vincent Basin of South Australia.
In the original description, Powell described the species as follows:
The holotype of the species measures in height and has a diameter of . It is similar in appearance to F. peramoena, but more slender. The species can be distinguished from other members of the genus due to the persistent angulate periphery on the body whorl, being relatively more slender, and the body whorl being less rounded.
The species was first described by A. W. B. Powell in 1944. The holotype was collected in 1919 by W. Howchin and J.C. Verco from the Metropolitan Abattoirs Bore in Adelaide, at a depth of between . It is held by the Auckland War Memorial Museum.
This extinct marine species occurs in middle Miocene strata of the St Vincent Basin of South Australia, including the Dry Creek Sands.
