Etymology. In honor of Christian Köberl, Director General of the Natural History Museum in Vienna from to June 2010 to May 2020.

Diagnosis. Perrona species of medium size, moderately slender fusiform shell with high, slightly gradate spire, short, conical to subcylindrical whorls with slightly carinate subsutural collar, last whorl angled at collar and strongly angled at shoulder, peribasal cord placed very high, just below shoulder, base broad, evenly concave, entire surface sculptured by fine spiral cords.

Description. Shell medium-sized, moderately slender, fusiform with high, weakly gradate spire; apical angle 32–36°. Protoconch not preserved. Teleoconch of eleven whorls. Early teleoconch whorls weakly concave with two weak, faintly beaded adsutural spiral cords, separated by concave mid-portion bearing fine, opisthocline axial riblets. Later whorls relatively short, subcylindrical, with narrow, poorly delimited, weakly carinate subsutural collar, flat-sided below, periphery at abapical suture. Delicate spiral cords on entire shell surface; subobsolete on late teleoconch whorls in some specimens. Suture narrowly incised, superficial, linear. Last whorl 50–55% of total height. Subsutural collar weakly carinate, delimited. Subsutural ramp flattened, very weakly concave, delimited by strongly angular shoulder cord placed at level of insertion of outer lip. Peribasal cord placed high, just below shoulder cord. Base moderately constricted, broadly concave, siphonal fasciole weakly swollen. Entire surface covered in fine spiral cords of alternating strength over base and fasciole. Aperture moderately wide, pyriform. Outer lip not thickened, smooth within. Anal sinus deep, moderately wide, asymmetrically U-shaped, with apex just below subsutural collar. Siphonal canal moderately short, moderately narrow, straight, shallowly notched at tip. Columella weakly excavated, slightly twisted at fasciole, smooth. Columellar and parietal callus thin, adherent, poorly delimited from base, forming rim.

Discussion. This species was identified by Hoernes & Auinger (1891) as Pleurotoma (Clavatula) carinifera , which was originally described by Grateloup (1832) from the Burdigalian of France. Hoernes & Auinger (1891) referred to the schematic drawing in Grateloup (1846, pl. 19, fig. 17) and to the description of a Langhian specimen from Italy by Bellardi (1877, pl. 6, fig. 24). Perrona carinifera , as described and illustrated by Peyrot (1931, pl. 6, figs 28, 30, 31, 33, pl. 8, figs 30, 31), differs from the Paratethyan species in its more strongly carinate subsutural collar and its conical spire. Moreover, the French species has a much longer siphonal canal. As already discussed by Peyrot (1931), the Italian specimen illustrated by Bellardi (1877, pl. 6, fig. 24) as ‘ Clavatula ’ carinifera , is not conspecific with the French species either. It has subcylindrical whorls and a swollen subsutural collar. In these features it is closer to the Paratethyan species, but differs in its more gradate spire and the suprasutural spiral cord. The weakly carinate collar and the angulated shoulder, along with the more prominent spiral sculpture, distinguish Perrona koeberli nov. sp. from Perrona lydiae ( Hoernes & Auinger, 1891) . Records of ‘ Perrona carinifera ’ from Herend and Pécsszabolcs ( Hungary), mentioned by Kókay (1966) and Bohn-Havas (1973), will need verification, but might rather refer to Perrona vindobonensis or P. ilonae .

Paleoenvironment. At the locality Grund fossiliferous channel fills, which formed in middle to outer neritic environments bear allochthonous assemblages uniting coastal-mudflat faunas with inner neritic ones ( Zuschin et al. 2005; Roetzel 2009). Preservation and color of the shells, suggest, that Perrona koeberli belonged to the allochthonous shallow water fauna and not to the autochthonous deep-water fauna.

Distribution in Central Paratethys. Badenian (middle Miocene): North Alpine-Carpathian Foreland Basin: Grund ( Austria) ( Hoernes & Auinger 1891).
