Neuburgensia rara Gründel & Nützel, 2024, sp. nov.

Neuburgensia rara sp. nov. Plate 10: figs 7–9 Etymology. Latin rare, because this species is rare. Holotype. SNSB-BSPG 2016 XXI 1856, the only specimen, Saal, collection Sylla. Diagnosis. Shell very slender, high-spired, with many whorls; early whorls have a subsutural, weakly tuberculate bulge that is reduced on later whorls; base flat; transition from whorl face to base at sharp angulation that is almost perpendicular. Type locality and stratum. Upper Jurassic (Kimmeridgian) reefal limestones from the locality Saal near Kelheim, Lower Bavaria (Gründel et al. 2015, 2022). Description. Shell very slender, high-spired, with many whorls; specimen is 30 mm high, with about 20 whorls, apex missing; early whorls increase more rapidly than the later ones and therefore, the early shell have a wider apical angle than later shell; early whorls with distinct subsutural bulge (sometimes nodular) emphasizing sutures; bulge reduced on later whorls; whorl face straight, sutures only slightly impressed; series of small cusps occasionally visible directly below suture; weak spiral lirae on whorl face (hardly visible due to preservation); base flat; transition from whorl face to base at sharp angulation, angle almost perpendicular with reinforced edge (visible above suture); growth lines weakly opisthocyrt on whorl face and prosocyrt on base; aperture outline rounded-rectangular, details of aperture not preserved; columella hollow. Remarks. In other Neuburgensia species, the subsutural bulge is not reduced during ontogeny.
