Description. Shell moderately small, solid, moderately broad, with high, weakly gradate spire. Protoconch poorly preserved in available specimens; high conical of about three moderately convex whorls. Teleoconch of six whorls. Spire whorls subcylindrical with periphery at abapical suture. Sculpture consisting of close-set, prominent, slightly prosocline axial ribs, separated by narrower interspaces. Well-defined, narrow subsutural cord delimiting subsutural collar; ribs above cord slightly swollen forming subquadratic nodes, but not distorting whorl profile. Second narrow cord appears just above suture on penultimate whorl. Last whorl moderately convex, moderately constricted at base. Axial sculpture and adsutural spiral cord persisting on last whorl. Prominent spiral cords on base override axial ribs, slightly swollen over the ribs, forming subquadratic to spirally elongated beads. Spiral cords on siphonal fasciole. Aperture small. Outer lip thickened, weak inner labial callus pad, with about six denticles; D1 strongest, weakening abapically. Anal canal weakly incised, broad V-shaped. Siphonal canal moderately long, narrow, slightly deflected, shallowly notched at tip. Columellar callus forming narrow rim, weakly detached from base, with four low columellar denticles. Parietal callus indistinct, not thickened, adherent.

Shell measurements and ratios. SL: 8.3–9.2 mm, MD: 3.3–3.7 mm, AA: 32–37°, SL/MD: 2.8–2.6, AL/AW: 3.6–4.3, LWH/AH: 1.3–1.4.

Discussion. Scabrella haueri   is superficially reminiscent of Nassarina Dall, 1889   (type species Nassarina bushii Dall   , present-day, Caribbean. Van Dingenen et al. (2017: 29) and Landau et al. (2019: 166) reported several Nassarina species   from the Neogene of the northeastern Atlantic. These species are all characterised by their rounded whorls, cancellate sculpture on the spire whorls due to the prominent spiral cords. Thus, despite the beaded spiral cords on the base of Scabrella haueri   , a placement in Nassarina   is unlikely. The specimen from the middle Miocene of the Loire Basin, described by Glibert (1852) as Pyrene haueri   , differs in its coarser axial ribs and the predominant spiral sculpture on the base, which lacks the beads of the Paratethyan species. Thus, the northeastern Atlantic species should be separated from the Paratethyan occurrences under the name Scabrella amaena (Ivolas & Peyrot, 1901)   . Scabrella haueri   differs from S. scabra ( Bellardi, 1848)   in its close-set axial ribs and wider apical angle (see Ferrero Mortara et al. 1981, pl. 58, figs 6a–b).

Palaeoenvironment. Inner neritic sand bottoms (see Mandic et al. 2002 for the Niederleis section and Zuschin et al. 2004 for data on the Kleinebersdorf section).

Distribution in Central Paratethys. Karpatian (early Miocene): Korneuburg Basin: Kleinebersdorf ( Austria) (Harzhauser 2002); Badenian (middle Miocene): North Alpine-Carpathian Foreland Basin: Lysice, Jaroměřice nad Rokytnou (the Czech Republic); Vienna Basin: Niederleis, Sparbach ( Austria) ( Toth 1950); Sedlec (Porzteich) (the Czech Republic) (own data); Eisenstadt-Sopron Basin: Forchtenau ( Austria); Făget Basin: Coşteiu de Sus ( Romania) ( Boettger 1906).

Genus Auingeria   nov. gen.

Type species. Columbella bellardii Hörnes, 1852   . Middle Miocene , Austria   .

Etymology. In honour of Mathias Auinger (1810–1890), Austrian palaeontologist at the Natural History Museum in Vienna and specialist for Paratethyan gastropods.

Diagnosis. Medium sized, moderately broad shell with gradate spire and subcylindrical whorls. Early teleoconch smooth with adsutural spiral cord and various spiral and/or axial sculpture on later teleoconch whorls. Characterised by lirate outer lip and long, narrow siphonal canal.

Description. Medium sized, moderately broad shell with gradate spire and subcylindrical whorls. Protoconch conical multispiral of 3.5 convex whorls. Teleoconch whorls with adsutural cords or cords just below adapical suture reinforced. Spiral sculpture of prominent to weak spiral cords. Axial ribs may be developed, the cords overrunning the ribs, slightly swollen at their intersections. Aperture narrow to moderately narrow. Outer lip weakly thickened, without internal labial callus pad, bearing elongated lirae with, extending deep within the aperture. Siphonal canal long, narrow, deflected. Narrow columellar callus rim bearing strong denticles.

Stratigraphic and geographic range. Middle Miocene (Badenian, Langhian), Central Paratethys Sea.

Included species. Columbella (Anachis) austriaca Hoernes & Auinger, 1880   , Columbella Bellardii Hörnes, 1852   , Auingeria grussbachensis Csepreghy-Meznerics, 1969   .

Palaeoenvironment. The type species derives from middle neritic to outer neritic settings.

Discussion. As can be seen from the three species included in the genus Auingeria   nov. gen., the adult sculpture is highly variable and not diagnostic. The characters that unite these species are the form of the early teleoconch whorls, the shell profile with subcylindrical whorls and strongly gradate spire, the long lirae within the outer lip, and the long siphonal canal. Independently, these features are seen in other genera, the profile of the last whorl and long siphonal canal is similar to species placed in the genus Orthurella Sacco, 1890   , and indeed Auingeria austriaca   was placed by Sacco (1890b) (as Columbella (Macrurella) adiecta   ) in Macrurella Sacco, 1890   , which is treated herein as synonym of Orthurella Sacco, 1890   . However, Auingeria   is distinguished from Orthurella   by its stepped outline of the early teleoconch, the spiral sculpture, the relatively wider aperture, shorter siphonal canal and the lirae in the outer lip.

The sculpture of spiral grooves is reminiscent of Sulcomitrella Kuroda, Habe & Oyama, 1971   (type species Mitrella monodonta Habe, 1958   ), which has been documented from the European Miocene by Landau et al. (2019) and herein. The long siphonal canal of Auingeria   however, excludes a closer relation with Sulcomitrella   .

There is also some resemblance to the fossil Caribbean genus Metulella Gabb, 1873   (see Jung 1994), especially Auingeria bellardii (Hoernes, 1852)   which has very similar sculpture. However, they differ in shell profile, the spire is not gradate and the last whorl not barrel-shaped as in Auingeria   . Moreover, the apertural dentition is quite different, with strong short labial denticles in Metulella   rather than lirae.

Auingeria   does not seem to have been endemic to the Paratethys, as we consider Columbella adiecta Sacco, 1890 a   subjective junior synonym of A. austriaca ( Hoernes & Auinger, 1880)   , extending its range to the middle Miocene Proto-Mediterranean Sea.
