Type material. Holotype: NHMW 1865 View Materials /0015/0060, SL: 13.7 mm, MD: 7.0 mm, Lysice ( Czech Republic), Figs 15J View FIGURE 15 , 41A View FIGURE 41 .
Type locality. Lysice ( Czech Republic), North Alpine-Carpathian Foreland Basin .
Type stratum. Brno Sand Formation.
Age. Middle Miocene, early/middle Badenian (Langhian).
Etymology. Referring to the figure Obelix of the comic Asterix by René Goscinny and Albert Uderzo, based on the shape of the shell.
Diagnosis. Small, stout, biconic shell with paucispiral protoconch, conical spire, adpressed suture and inflated last whorl with prominent terminal varix, sculpture of weak, widely spaced primary spiral cords with one or two delicate secondary cords in interspaces, aperture with very weak parietal denticle, without anal denticle.
Description. Small, stout, biconic shell of five almost straight sided whorls; apical angle 57°. Protoconch paucispiral of 1.5 convex whorls; diameter: 700 μm, height: 620 μm. First teleoconch whorl with low, broad axial ribs overrun by four broad spiral cords, swollen over ribs; periphery close above abapical suture. Interspaces distinctly widening on later whorls, bearing one delicate secondary cord intercalated between primaries. Axial ribs weakening adapically, subobsolete on fourth teleoconch whorl. Penultimate whorl weakly concave adapical half, weakly convex below. Suture narrowly impressed. Last whorl ovate, attaining 70% of total height, somewhat inflated mid-whorl, bearing spiral sculpture of weak primary cords with two even weaker secondaries intercalated in interspaces; no axial sculpture; prominent terminal varix; base moderately constricted; fasciole slightly swollen forming narrow chink, with weak spiral cords.Aperture moderately wide, broad pyriform. Columellar callus forming broad rim, adherent in parietal region. Columella moderately excavated, smooth, weakly angled, with small denticle at transition into siphonal canal, very weak parietal swelling. Anal canal weakly incised without anal denticle. Outer lip with about eight prominent lirae, starting short distance behind peristome, extending deep within aperture. Siphonal canal incomplete, at least moderately long, wide, slightly deflected to the left.
Discussion. This species is characterized by its stout biconical shell and prominent spiral sculpture. Euthria subnodosa (Hoernes & Auinger, 1890) has broader spiral cords and is slenderer. Euthria fuscocingulata (Hoernes & Auinger, 1890) has a higher last whorl, and lacks spiral sculpture on the last whorls and Euthria zboroviensis Friedberg, 1912 differs in its more convex spire whorls and bears axial ribs on the last whorl.
Paleoenvironment. Unknown.
Distribution in Central Paratethys. Badenian (Middle Miocene): North Alpine-Carpathian Foreland Basin: Lysice ( Czech Republic).
