Revised description. Medium sized, moderately slender fusiform shell of up to seven teleoconch whorls; apical angle 40–44°. Protoconch unknown from holotype [paucispiral pointed in specimen illustrated in Kovács & Vicián 2023: 236, figs 6K–L]. First three teleoconch whorls weakly convex with broad, prosocline axial ribs, separated by wider interspaces, fading towards adapical suture; eight on third teleoconch whorl. Spiral sculpture on early teleoconch whorls of broader, not very prominent subsutural cord and four weak primary spiral cords, with single delicate secondary intercalated in interspaces and at abapical suture; spirals rapidly weaken on fourth whorl and become subobsolete or absent on subsequent whorls. Later whorls almost straight sided, forming conical spire with adpressed suture. Last whorl attaining 62–69% of total height, subsutural ramp hardly delimited, marked by slightly concave portion below suture, convex and slightly swollen mid-whorl, strongly constricted at base; fasciole narrow, swollen, forming narrow pseudoumbilicus. Seven vague axial swellings appear on last half of whorl; faint impression of spiral sculpture over subsutural ramp and mid-whorl, base and siphonal canal with narrow spiral cords of alternating strength. Aperture narrowly pyriform. Columellar callus thickened, forming broad rim, sharply delimited from base. Columella moderately excavated in upper half, with three weak columellar folds on abapical half; two folds more prominent, slightly recessed within aperture; third fold coinciding with weakly angled transition to siphonal canal. Broad parietal denticle accentuates deeply incised anal canal. Outer lip not thickened with seven prominent, widely spaced lirae close behind peristome, extending deep within aperture. Siphonal canal long, narrow, straight, slightly deflected to the left, shallowly notched.
Discussion. Specimens from the Burdigalian of the Colli Torinesi ( Italy) illustrated by Bellardi (1884) and Cossmann (1901) might be conspecific with Neolatirus recticauda (Fuchs in Karrer, 1877) but more and betterpreserved material would be needed to verify this. Latirus obliquicauda Bellardi, 1844 , from the Burdigalian of Baldissero ( Italy), differs only in its slightly more convex last whorl and is tentatively synonymized herein with Neolatirus recticauda ; note that the illustration in Bellardi (1884: pl. 2, fig. 32) is misguiding, showing a strongly twisted siphonal canal, instead of a straight canal as seen in the picture provided by Ferrero Mortara et al. (1981: pl. 39, fig. 3). Specimens from Letkés ( Hungary), described by Csepreghy-Meznerics (1956) as Fasciolaria bellardii were identified as Neolatirus recticauda by Kovács & Vicián (2023).
Paleoenvironment. Unknown for the type locality. The occurrence at Letkés ( Hungary) points to inner neritic environments with corals ( Kovács & Vicián 2014) .
Distribution in Central Paratethys. Badenian (Middle Miocene): Vienna Basin: Rauchstallbrunn-Graben at Baden ( Austria) (Fuchs in Karrer 1877); Pannonian Basin: Szob, Letkés ( Hungary) ( Strausz 1966; Kovács & Vicián 2023).
Proto-Mediterranean Sea. Burdigalian (Early Miocene). Colli Torinesi: Valle Ceppi, Baldissero ( Italy) ( Bellardi 1884).
Genus Polygona Schumacher, 1817
Type species. Polygona fusiformis Schumacher, 1817 View in CoL [= Polygona infundibulum ( Gmelin, 1791) View in CoL ], by monotypy. Present-day, Caribbean Sea.
Diagnosis. “ Adult shell small to large, maximum length of adults 30 to 100 mm, fusiform, basally constricted, spire high but usually equal to or shorter than aperture plus canal, siphonal protuberance long; axial sculpture of last whorl consisting of low, broad, rounded ribs; spiral sculpture varying from obsolete to strong, high cords, forming nodes only when intersecting axial ribs at shoulder angulation (if present); outer lip planar to medially convex, with weak adapical sinus and weak or absent abapical sinus; edge of adult outer lip minutely reflected, with paired crenations on central sector; adaxial side of outer lip with smooth or beaded lirae, which in some species (including the type) form a slightly enlarged abapical denticle deeply recessed in aperture; inner lip with two or three folds, and in the adult an adapical parietal nodule; pseudoumbilicus usually present.” Vermeij & Snyder (2006: 419).
Discussion. It is likely that Polygona is a polyphyletic group. We note that Polygona lynchi has smooth lirae, whereas most American species have beaded ones. The type, Polygona infundibulum , also has smooth lirae, as does Polygona brevicaudatus ( Reeve, 1847) ; both seem closer to the eastern Atlantic species than, for example Polygona angulata ( Röding, 1798) and its relatives, which have beaded lirae.
