Upper Jurassic (Kimmeridgian) reefal limestones from the locality Saal near Kelheim, Lower Bavaria ( Gründel et al. 2015, 2022).
Diagnosis.
Shell slender, oval; spire whorls low; body whorl much higher than spire, with weakly, evenly convex whorl face.
Description.
Shell slender, oval, higher than wide; holotype 18 mm high; sutures distinct; body whorl nearly two times higher than spire, with weakly, evenly convex whorl face; periphery low on whorl; transition from whorl face to base evenly rounded; base stronly convex; shell smooth; growth lines weakly parasigmoidal; aperture incomplete, probably teardrop-shaped.
Remarks.
Similar species (e. g., Oonia guirandi Loriol in Loriol and Bourgeat 1886–1888, Pseudomelania (Oonia) cornelia (d’Orbigny) sensu J. – C. Fischer et al. (2001) and Fischer and Weber 1997, Ampullospira (Pictavia) calypso (d’Orbigny) sensu Fischer and Weber 1997 ) usually have higher spire whorls, but above all, a wider and more convex body whorl.
