Additional paratypes: NHMW 1846/0037/0278, Baden ( Austria); 1 spec., NHMW 1860/0015/0686, Niederleis ( Austria).
Type locality. Enzesfeld ( Austria), Vienna Basin .
Type stratum. Baden Formation.
Age. Middle Miocene, middle Badenian (Langhian).
Etymology. In honor of Gregor Schuberth, architect in Vienna, in gratitude for the goof cooperation with the first author.
Diagnosis. Medium-sized, stocky fusiform shell characterized by low, strongly convex whorls with deeply incised suture and strongly constricted last whorl and broad, prominent prosocline axial ribs; narrow columella fold placed just above transition to siphonal canal.
Description. Medium-sized, stocky fusiform shell; apical angle ~52°. Protoconch unknown. Teleoconch of up to six whorls. Suture deeply incised, shallowly undulating. Early teleoconch whorls strongly convex with weakly angled periphery placed mid-whorl. Axial sculpture of nine broad, swollen, prosocline axial ribs overrun by eight prominent spiral cords, separated by interspaces of equal width with delicate growth lines. Last whorl attaining ~63% of total height, with broad, strongly convex periphery, strongly constricted below. Sculpture of seven prominent axial ribs, fading over base. Regular sculpture of primary and secondary spiral cords with delicate, cancellate sculpture in interspaces. Fasciole swollen, covered by numerous spiral cords, delimiting narrow pseudoumbilicus. Aperture narrowly pyriform. Columella strongly excavated with weak columellar fold close to angled transition to siphonal canal. Columellar callus adherent, thin, poorly delimited from base. Anal canal indistinct, wide. Outer lip weakly thickened with about 8 long lirae, fading deep in aperture. Siphonal canal long, moderately wide, slightly bent to the left.
Discussion. Janssen (1972) placed the specimen illustrated by Hörnes (1853: pl. 32, figs 4a–b) in the Ocinebrinae genus Urosalpinx Stimpson, 1865 [type species Fusus cinereus Say, 1822 ; present-day, western Atlantic]. Urosalpinx , however, lacks lirae in the outer lip and does not develop a columellar fold. Hörnes (1853) and Janssen (1972) identified the Paratethyan species as Fusus sismondai Michelotti (1847) from the Burdigalian or Langhian of the Colli Torinesi ( Italy). The Italian species is poorly known, but based on the illustration in Michelotti (1847: pl. 17, fig. 14), it differs from the Paratethyan species in in its more numerous axial ribs and more angular last whorl [specimens illustrated by Sacco (1904; pl. 8, figs 18–21) as this species differ considerably from the figure in Michelotti (1847) and represent at least two other species]. “ Urosalpinx sismondai ” sensu Janssen (1972) from the Miocene of the North Sea, is a morphologically closely related species but differs in its coarser sculpture, broader pseudoumbilicus and lacks a distinct angulation of the columella (see Janssen 1972: pl. 7, fig. 3). Herein, we tentatively place this species in Pseudofusus but note that the pseudoumbilicus is an atypical feature for the genus.
Paleoenvironment. Inner to outer neritic environments.
Distribution in Central Paratethys. Badenian (Middle Miocene): North-Alpine-Carpathian Foreland Basin: Jaroměřice nad Rokytnou ( Czech Republic) (Hoernes & Auinger 1890). Vienna Basin: Baden, Enzesfeld, Niederleis ( Austria); Boršov (= Porstendorf) ( Czech Republic) (Hoernes & Auinger 1890).
