Mauidrillia torquayensis is an extinct species of sea snail, a marine gastropod mollusc in the family Horaiclavidae.[1] Fossils of the species date to the late Oligocene strata of the Port Phillip Basin of Victoria, Australia.
In the original description, Powell described the species as follows:
Species superficially similar to aldingensis, but more likely derived from pullulascens, from which it differs in being broader, with a stronger, more persistent peripheral angulation and strong axial knobs. Subsutural fold indistinctly defined on early whorls only. Four fine spirals on shoulder. Five to six stronger cords from angle to lower suture on spire-whorls, about 25 on body-whorl, base, and anterior end. Interspaces slightly more than width of spirals. Axials strong at periphery, but becoming obsolete before reaching either suture.[2]
The holotype of the species measures 9.1 mm (0.36 in) in height and 3.9 mm (0.15 in) in diameter.[2]
