Type material. Holotype: M5 , specimen illustrated in Strausz (1959: pl. 3, figs 18–22), SL: 9 mm, MD: 14 mm, Szob ( Hungary). We have not been able to trace the type specimens, which might be stored in the Mining and Geological Survey of Hungary, Budapest.

Revised description. Small, robust, spherical to depressed globose shell of ~3.5 teleoconch whorls ( SL /MD = ~1.0–1.5). Protoconch poorly preserved, low conical with weakly convex whorls. Spire low conical, to weakly elevated; apical angle 135–140°. Earliest teleoconch whorls narrowly coiled, later whorls strongly widening. Suture linear, adpressed. Teleoconch whorls with moderately wide, weakly convex subsutural shelf, delimited by faint shoulder angulation. Last whorl moderately expanding, attaining ~95% of total height. Periphery regularly convex, below mid-whorl (~41%). Growth lines weak and weakly prosocyrt in apical view, weak to subobsolete at periphery. Aperture relatively narrow, D-shaped, prosocline. Position of adapical tip of aperture moderately high (~85%), distinctly below shoulder, above mid-whorl. Aperture attaining ~75% of total height. Columellar lip broad, reinforced; basal lip thickened, outer lip thin. Columellar angle ~16–22°. Weak opercular ridge in outer lip. Umbilicus reduced to moderately narrow (~14%), deep, circular opening. Parietal callus moderately long (~48%), slightly thickened, with concave margin, grading into large, tongue-shaped, moderately thickened anterior lobe, forming conspicuous umbilical callus adherent and following outer umbilical wall until about ¼ of whorl before aperture. Funicle covered by umbilical callus. Umbilicus abapically delimited by spiral ridge bent towards interior of umbilicus. Basal fasciole rounded, thickened with prominent growth lines. No color pattern preserved.

Discussion. This species is unique among Paratethyan Naticidae due to its large, tongue-shaped anterior lobe, which encloses most of the umbilicus, leaving a narrow opening. Euspira subobturata sensu Robba et al. (2016 : pl. 10, figs 2–4) ( non Sacco, 1891), from the Burdigalian and Langhian of the Colli Torinesi ( Italy), might be a closely related species but differs in the shorter anterior lobe. The original Euspira subobturata ( Sacco, 1891) , from the Pliocene of Italy, differs in its elongate-ovate outline and less prominent anterior lobe (see Robba et al. 2016: pl. 10, fig. 1). The Pliocene Mediterranean Natica virguloides Sacco, 1890 is superficially reminiscent of Figovina szobiensis due to its tongue-shaped umbilical callus, but this structure is much smaller than in the Paratethyan species and consequently the umbilicus is much wider ( Pedriali & Robba 2005: pl. 6, figs 11–15). The recent South African Natica queketti G. B. Sowerby III, 1894 is very similar to Figovina szobiensis in outline, size and umbilical features, but has a shorter ‘tongue’ and a generally less excessive umbilical callus. The extant species is currently placed in Natica by Torigoe & Inaba (2011), but this placement will need confirmation.

Paleoenvironment. Shallow marine, inner neritic.
