REMARK
This is the only terrestrial pulmonate gastropod in the Selsoif fauna. Ellobiids typically live in supratidal habitats. This species has usually been placed in the genus Ellobium Röding, 1798 but Harzhauser et al. (2023) showed that Ellobium is an Indo-Pacific genus that disappeared from the European faunas around the Oligocene/Miocene boundary. Therefore, attribution to a more appropriate genus is required but that is beyond the scope of this work.
