MATERIAL AND DIMENSIONS. — Maximum height 1.5 mm, width 0.8 mm. — RGM.1365261 (1), leg. ACJ .

SPECIES CHARACTERISATION. — Thin shelled hydrobiid with marked convex whorl profile and relatively deep suture; aperture rounded. The specimen at hand suffers from corrosion of the outer shell layer, hence its uncertain attribution.

DISTRIBUTION. — Lower Pliocene: Iceland ( Símonarson et al. 2021). — Upper Pliocene: NSB, Red Crag, England ( Hoeksema & Raad 2015). — Lower Pleistocene: Maassluis Formation, Netherlands (RGM collection); Atlantic, Selsoif, NW France (this paper). — Pleistocene and Holocene (indeterminate): NSB, Netherlands ( Hoeksema & Raad 2015). Today it occurs along the European coasts from Norway and the Baltic to the Mediterranean and Black Sea ( Fretter & Graham 1978).
