Mauidrillia partinoda is an extinct species of sea snail, a marine gastropod mollusc in the family Horaiclavidae.[1] Fossils of the species date to the middle Miocene strata of the Port Phillip Basin of Victoria, Australia.
In the original description, Powell described the species as follows:
Species close to Mauidrillia pullulascens|pullulascens, but with the axials reduced to weak tubercles on the carina of the first two to three post-nuclear whorls only, 11 per whorl. Spiral sculpture consisting of a subsutural margining cord, two weaker cords on the shoulder, the moderately strong peripheral cord at the middle of the whorls, 2 to 3 weaker cords below it, plus 8 on the base and a further 8 linear-spaced threads on the anterior end. The whorls are only slightly angled.[2]
The holotype of the species measures 8.4 mm (0.33 in) in height and 4 mm (0.16 in) in diameter.[2]
