Revised description. Small, ovate-globose shell of four teleoconch whorls; higher than wide ( SL /MD = ~1.1); spire moderately high, conical, apical angle 108–112°. Protoconch unknown. Suture linear, slightly impressed. Teleoconch whorls with faint subsutural cord, shallow, weakly concave subsutural ramp, delimited by widely rounded shoulder. Periphery and base regularly convex. Last whorl weakly expanding, attaining 90% of total height. Periphery below mid-whorl (~45%). Growth lines delicate and weakly prosocyrt in apical view, delicate to subobsolete at periphery. Aperture narrowly D-shaped, prosocline, attaining ~65% of total height. Position of adapical tip of aperture moderately low (~72%), at or slightly below periphery, far below shoulder. Columellar lip weakly reinforced, basal lip solid, outer lip thin. Columellar angle ~15–25°. Parietal callus moderately long (~49%), strongly thickened with concave margin; not expanding over base. Anterior lobe moderately thick expanding, sub-triangular. Umbilicus wide (~17%), deep; funicle forming narrow, raised cord deep in umbilicus with narrow adapical sulcus and wider, deeply concave abapical sulcus, delimited by very prominent spiral ridge bent towards interior of umbilicus. Umbilical callus triangular, fused with anterior lobe but with slight notch between anterior lobe and umbilical callus. Basal fasciole solid, weakly angled towards aperture, with prominent growth lines. Color pattern uniformly tan.

Discussion. Glibert (1952a) listed this species as Polynices helicina f. badensis (Partsch) , although there exists no publication by Partsch in which this species would have been mentioned or described. Consequently, the authorship has to be passed to Glibert (1952a). Glibert (1952a) established this species as subspecies (or ‘forma’) of Euspira helicina ( Brocchi, 1814) , but the umbilical features with the characteristic spiral ridge delimiting the umbilicus exclude a close relation with this Pliocene species and places this species in the genus Payraudeautia . Payraudeautia badensis (Glibert, 1952) was confused in the collection of the NHMW with specimens described herein as Euspira protracta ( Eichwald, 1830) , which has a similar outline but lacks a spiral ridge and a cord-like funicle. The late Miocene-Pliocene Payraudeautia fasciolata ( Sacco, 1890) and the Pliocene to recent P. intricata (Donovan, 1804) are both lower spired with a more globose last whorl, and a more developed funicular callus (see Pedriali & Robba 2009: pl. 2, figs 11–14).

Paleoenvironment. Occurrences in the Baden Formation of the Vienna Basin suggest middle to outer neritic settings in up to 250 m water depth ( Kranner et al. 2021) .
