Type material. Holotype, PAL 2022.54.1, SL: 22.0 mm, MD: 10.5 mm, Parádfürdö , Ilona Valley ( Hungary), illustrated in Kovács et al. (2023: figs 58–59), Figs 17C View FIGURE 17 1 –C View FIGURE 1 2 View FIGURE 2 .

Revised description. Shell large, robust, moderately slender (apical angle ~23°). Protoconch and early teleoconch whorls unknown. Teleoconch whorls convex with broad, moderately steep, weakly concave, very poorly delimited subsutural ramp, with periphery just below mid-whorl. Suture moderately impressed, relatively shallow. Sculpture of very numerous, close-set, narrow, prosocline, weakly frondose axial ribs, not strictly aligned axially (23 axial ribs on penultimate whorl). Axial ribs overrun by about five spiral cords of equal strength to ribs, forming fine cancellate pattern. Three very prominent, convex varices per whorl vaguely obliquely aligned axially. Secondary spiral cords intercalated on last whorl numbering about 12. Base slowly contracting with narrow, weak basal cord and flattened disc. Aperture subcircular. Columella concave. Outer lip strongly thickened by varix, basal lip broad. Peristome very broad, duplex. No umbilicus.

Discussion. We are not aware of comparable species in the Circum-Mediterranean region.

Paleoenvironment. Agitated, coastal marine ( Kovács et al. 2023).

Distribution in Central Paratethys. Ottnangian (Early Miocene): Early Miocene North Hungarian Basin: Parádfürdö ( Hungary) ( Kovács et al. 2023).
