Type locality. Grund ( Austria), North Alpine-Carpathian Foreland Basin .

Type stratum. Grund Formation.

Age. Middle Miocene, early Badenian (Langhian).

Etymology. In honor of Anton Breitenberger (Bad Vöslau, Austria), who always supports us by providing access to his collection.

Diagnosis. Small, moderately broad, turreted shell with large, slightly inflated last whorl and sculpture of numerous delicate, thin, weakly raised lamellae and numerous delicate spiral threads.

Description. Shell small, moderately broad, elongate conical or weakly coeloconoid, turreted (apical angle ~24–26°). Protoconch unknown. Teleoconch of at least eight strongly convex whorls with weakly concave subsutural ramp, faintly angled periphery placed mid-whorl. Suture deeply impressed, linear. Sculpture of numerous, delicate, weakly raised, weakly prosocline lamellae, separated by wider interspaces, slightly more prominent close to adapical suture (~25/30: ~25/35: ~30/40). Interspaces with numerous delicate spiral threads. Last whorl large, slightly inflated, attaining about 45% of total height, with rounded shoulder angulation placed just above mid-whorl, weak basal angulation without peribasal cord, base weakly convex with distinct lamellae and numerous delicate spiral threads. Short, broad fasciole with prominent growth lines. Aperture ovate, columella weakly concave. Outer lip and basal lip thin. Columellar callus forming broad, thin, attached rim. No parietal callus. No umbilicus. Peristome simple.

Discussion. This species was confused by Kecskeméti-Körmendy (1962) with the eastern Pacific Aspersiscala minuticosta (de Boury 1912) , which differs in its deep and wide umbilicus (see de Boury 1912: pl. 7, fig. 1). Subuliscala banoni ( Tournouër, 1874) and Subuliscala lagusensis (de Boury in Cossmann, 1912), from the Burdigalian of France, both differ from the Paratethyan species in their much slenderer shells (see Tournouër, 1874: pl. 9, fig. 4, Cossmann 1912: pl. 2, figs 12–13, 14–15; Cossmann & Peyrot 1922: pl. 4, figs 22–23, 35, 41–42, 49–50). Adiscoacrilla interposita ( Sacco, 1891) , from the Tortonian of the Po Basin, differs in its broader, conical shell and more prominent varices (see Ferrero Mortara et al. 1984: pl. 6, fig. 10).

Subuliscala breitenbergeri sp. nov. is most similar to Subuliscala lagusensis (de Boury in Cossmann, 1912), from the Burdigalian of France, but differs in its weaker varices and slightly more coeloconoid spire (see Cossmann 1912: pl. 2, figs 14–15; Cossmann & Peyrot 1922: pl. 4, figs 49–50).

Paleoenvironment. At the locality Grund channels formed in middle to outer neritic environments and were filled, with allochthonous assemblages uniting coastal-mudflat faunas with inner neritic ones (Zuschin et al. 2005; Roetzel 2009). The preservation suggests that the shells might have belonged to the middle and outer neritic assemblages.

Distribution in Central Paratethys. Badenian (Middle Miocene):? Korytnica Basin: Korytnica ( Poland) ( Bałuk 2006); North Alpine-Carpathian Foreland Basin: Grund ( Austria) (hoc opus); Vienna Basin: Baden ( Austria) (hoc opus); Pannonian Basin: Várpalota ( Hungary) ( Kecskeméti-Körmendy 1962).
