Revised description. Small, moderately fragile, depressed shell of two auriculate teleoconch whorls, wider than high ( SL /MD = ~0.6–0.8). Protoconch low turbiniform of 2.7 convex whorls, diameter ~750 μm. Terminal part of first teleoconch whorl allometrically expanding, covering large part of initial first teleoconch whorl, resulting in somewhat ‘heterostrophic’ appearance of early spire. Teleoconch of two whorls. Spire depressed conical; apical angle 134–148°. Suture linear, weakly incised. Teleoconch whorls with very broad, weakly convex subsutural ramp, occasionally becoming weakly concave close to aperture. No shoulder angulation. Last whorl strongly expanding, attaining ~96% of total height. Periphery convex, placed far below mid-whorl (~30%). Growth lines weak on early teleoconch, prominent and prosocyrt in apical view on late last teleoconch whorl, subobsolete at periphery. Sculpture of first teleoconch whorl of 12–16 broad, flat spiral cords separated by subequal grooves. Cords widening with flat tops, occasionally becoming bifid, resulting in rather regular sculpture of broad spiral cords. Spiral sculpture only slightly wavy due to intersections with growth lines on last quarter of last whorl. Base slightly convex with densely spaced delicate spiral cords, crossed by prominent, opisthocyrt growth lines close to aperture. Aperture wide, ovate, strongly prosocline. Position of adapical tip of aperture high (~87%), distinctly above mid-whorl. Aperture attaining ~80–85% of total height. Columellar lip forming moderately broad, rim, detached from base. Basal lip and outer lip thin. Columellar angle ~30–40°. Umbilicus reduced to deep, narrow chink. Parietal callus short (~35%), forming thin sheet-like callus. No color pattern preserved.

Paratethyan synonyms. Sigaretus borsodensis Csepreghy-Meznerics, 1969 (Figs 66B 1 –B 2) is a subjective junior synonym of Sinum affine . Csepreghy-Meznerics (1969a, 1969b) did not state on which features she based her new species and did not refer to Sinum affine . Herein, we re-illustrate the type specimen, which does not differ significantly from Sinum affine . Therefore, we treat it as a subjective junior synonym.

Discussion. Pedriali et al (2019), who had better preserved material at hand, described protoconch I as smooth and protoconch II with widely spaced axial riblets (see Pedriali et al. 2019: figs 33/4a–c). Sinum affine ( Eichwald, 1830) is a rather common species in the Central Paratethys Sea and is characterized by its moderate size, broad, flat spiral cords and the slightly heterostrophic early spire. Although, the specimen illustrated by Pedriali et al. (2019: figs 33/4) has a normally coiled spire, their fig. 33/1 shows the same heterostrophic whorls as the material from the Vienna Basin. Sinum affine is most similar to the Middle Miocene to Pliocene Sinum striatum (de Serres, 1829) , which occurs in the northeastern Atlantic and Mediterranean Sea ( Van Dingenen et al. 2016; Pedriali et al. 2019). It also has a slightly heterostrophic early spire (see Pedriali et al. 2019: fig. 33/8) and identical sculpture but has a smaller and differently sculptured protoconch with granules instead of axial riblets and a more depressed shell ( Pedriali et al. 2019).
