Syntomodrillia waiauensis is an extinct species of sea snail, a marine gastropod mollusc in the family Drilliidae.[1] Fossils of the species date to the middle Miocene, and have been found at Clifden, Southland, New Zealand.
The species has a small fusiform shell, and a spire that is marginally taller than the aperture and canal combined. The shell has 6.5 whorls, including a protoconch of two whorls which are globular and smooth.[2] The holotype of the species measures 5.5 mm (0.22 in) in height and 2.3 mm (0.091 in) in diameter.[2]
