Revised description. Small, slender shell of 11 teleoconch whorls; apical angle 16–22°. Protoconch high conical of 2.75 convex whorls. Early teleoconch whorls flat sided with narrowly impressed suture. Sculpture of prominent opisthocline axial ribs separated by narrower interspaces. Whorl profile changing into concave, cylinder shaped around third to fourth teleoconch whorl due to development of prominent subsutural band. Axial ribs form row of tubercles over subsutural band and second weaker row just above suture, partly covered by subsequent whorl. Between rows of tubercles axial ribs obsolete. Last whorl high, ~35–37% of total height, angled at tubercles on subsutural band and mid-whorl by second row of tubercles. Base weakly contracting. Fasciole narrow, sharply delimited adapically by carina. Aperture narrow, elongated ovoid. Columella weakly to moderately excavated in adapical half. No columellar fold. Columellar callus forming thin, broad rim, not delimited from base. Anal canal narrowly incised, narrowed by weak parietal swelling. Outer lip thin with mid-whorl angulation. Basal lip convex, moderately wide. Siphonal canal very short, wide, moderately deeply notched.

Discussion. Hastula lapugyensis cannot be confused with any of its Paratethyan congeners due to its two rows of tubercles, just below the adapical suture and in contact with the abapical suture. Hastula algarbiorum (Pereira da Costa, 1867), from the Tortonian of Portugal and Italy, is a thick-shelled species, which differs in its weaker sculpture; it develops vague axial ribs on the subsutural band instead of tubercles and lacks tubercles at the abapical suture (see Pereira da Costa 1867: pl. 13, figs 3–6; Sacco 1891a: pl. 2, figs 56–60; Davoli 1977: pl. 1, figs 4–5, 17–18). The specimen from the Langhian of Mirabeau ( France), illustrated by Glibert (1952a: pl. 14, fig. 4a) as Hastula cf. algarbiorum , might represent an occurrence of Hastula lapugyensis in the Loire Basin. Juvenile specimens of Terebra golebiowskii nov. sp. are superficially similar ( Fig. 7F View FIGURE 7 ) but have a conical spire and lack beads on the swollen subsutural band.

Paleoenvironment. Unknown. The localities comprise assemblages from coastal inner neritic settings and from deeper water environments.

Distribution in Central Paratethys. Badenian (Middle Miocene): Pannonian Basin: Pécsszabolcs, Várpalota ( Hungary) ( Strausz 1954; Bohn-Havas 1973); southern Pannonian Basin: Hrvaćani ( Bosnia and Herzegovina) ( Atanacković 1985); Cserhát Mountains: Mátraverebély, Sámsonháza ( Hungary) ( Csepreghy-Meznerics 1954); Făget Basin: Lăpugiu de Sus ( Romania) ( Hoernes & Auinger 1880).

Northeastern Atlantic:? Langhian (Middle Miocene): Loire Basin: Mirabeau ( France) ( Glibert 1952a).
