?Mauidrillia laevis
The taxon was introduced in an unpublished PhD thesis. The sole collection is in the Naturhistorisches Museum Mainz, Paleontological Collection PWL1999-418-1326 it was collected in the Würzmühle Sand quarry which is part of the Alzey Formation (Rupelian, Oligocene) in the Alzey-Weinheim of Rheinland-Pfalz, Germany (see).
A second publication Muller (2011) lists Mauidrillia? sp. aff. laevis Gürs, 1995 with an illustration but without a description this is also invalid. This illustration gives us no confidence that the original referal of these taxa to Mauidrillia was correct.
