Additional studied material. NHMW 1868/0001/0069, SL: 43.7 mm, MD: 20.1 mm, Baden-Sooss ( Austria), Figs 12D 1 –D 2 , 3J .

Revised description. Shell moderately large, solid, stout biconic;apical angle~38-40°.Protoconch not preserved. Teleoconch of nine whorls. Early teleoconch whorls weakly concave with tripartite sculpture; beaded adsutural cords (abapical one more prominent) and finely beaded central spiral cord. Later whorls concave with narrow, weakly swollen subsutural collar, bearing widely spaced, indistinct, depressed, open spinous tubercles; broad, concave midportion, fine beaded mid-whorl cord disappears; suprasutural band with prominent tubercles frequently accentuated by strongly raised arcuate growth lines. Entire shells surface covered by numerous secondary spiral cords also overriding tubercles. Suture narrowly incised, running below beads. Last whorl 65–70% of total height; subsutural collar poorly delimited bearing low, open spines. Subsutural ramp broad, deeply concave. Shoulder prominent, strongly tubercular (about 18 tubercles), mid-whorl weakly convex, weakly angled at peribasal cord. Base strongly constricted; siphonal fasciole strongly swollen and twisted. Sculpture below shoulder consisting of elevated cords of primary to tertiary strength. Primary cords tubercular, all made scabrose by prominent, elevated, close-set growth lines. Aperture moderately wide, pyriform. Outer lip not thickened, smooth within. Anal sinus deep, moderately wide, asymmetrically V-shaped, with apex mid-ramp. Siphonal canal moderately long, moderately narrow, deflected to the left, unnotched. Columella strongly excavated in upper third, straight below, smooth. Columellar and parietal callus strongly thickened, sharply delimited, forming broad callus rim and deep pseudoumbilicus.

Discussion. ‘ Clavatula ’ hirmetzli Kovács & Vicián, 2021 is characterized by its large size, biconic outline and very solid shell. It is slightly reminiscent of ‘ C. ’ vitalisi Strausz, 1955 , but differs clearly in its shorter spire, the more prominent subsutural collar and the comparatively reduced sculpture along the central concavity of the whorls. Moreover, ‘ C. ’ vitalisi has a slightly cancellate sculpture along the abapical row of beads. ‘ Clavatula ’ raphana ( Millet, 1865), from the Tortonian of France, has a comparably stout outline with beaded angulation, but differs in its granulose, comma-shaped riblets on early teleoconch whorls (see Landau et al. 2020, pl. 76, figs 1–2).

Paleoenvironment. The occurrence at Letkés ( Hungary) suggests a preference for inner neritic environments in the vicinity of corals ( Kovács & Vicián 2013).

Distribution in Central Paratethys. Badenian (middle Miocene): Vienna Basin: Baden-Sooss ( Austria); Pannonian Basin: Letkés ( Hungary) ( Kovács & Vicián 2021).

Revised description (referring to Paratethyan specimen). Shell moderately large, moderately slender fusiform with high conical spire; apical angle ~40°. Protoconch not preserved. Teleoconch of ten whorls. Early teleoconch whorls flat-sided with tripartite sculpture; three spiral rows of beads, suprasutural row bifid by intercalation of narrow spiral groove; beads forming vague arcuate axial riblets. On fifth whorl central beaded cord disappears, subsutural beaded cord separated from suprasutural bifid row of beads forming periphery by wide, concave mid-portion, with narrow, comma-shaped axial riblets. On penultimate whorl row of suprasutural beads further subdivided by narrow spiral cords of alternating strength. Suture narrowly incised, weakly undulating. Last whorl ~60% of total height; subsutural collar narrow, sharply delimited bearing single spiral groove at mid-collar. Subsutural ramp of moderate width, concave. Shoulder moderately developed, delimited by beaded cord, convex below, moderately constricted at base. Siphonal fasciole indistinct. Sculpture below ramp of narrow, densely beaded spiral cords of alternating strength, extending over base and siphonal fasciole. Aperture moderately narrow, pyriform; outer lip not thickened, smooth within; anal sinus deep, moderately narrow, asymmetrically U-shaped, with apex below collar. Siphonal canal moderately long, moderately narrow, straight to slightly deflected to the left, shallowly notched at tip. Columella smooth, strongly excavated in upper third, straight below, weakly twisted at fasciole. Columellar and parietal callus moderately thickened, sharply delimited, forming broad callus rim.

Discussion. ‘ Clavatula ’ interrupta ( Brocchi, 1814) is rare in Paratethyan deposits and many literature records represent ‘Clavatula’ sophiae ( Hoernes & Auinger, 1891) . See ‘ C. ’ sophiae and ‘ C. ’ olgae ( Hoernes & Auinger, 1891) for discussion of differences between ‘ C. ’ interrupta and these species.
