Revised description. Medium-sized, solid, moderately slender fusiform shell with conical spire; apical angle ~55–67°. Protoconch unknown. Teleoconch of up to five whorls. Suture weakly incised, linear. First two teleoconch whorls convex, later whorls with broad, straight sided to weakly concave subsutural ramp and angled shoulder placed below mid-whorl. Up to nine broad, weak axial ribs, fading over subsutural ramp. Spiral sculpture of weak subsutural threads and broad, close-set adis, IP and abis on antepenultimate and penultimate whorls; delicate tertiary cords may be intercalated. P1, P2 prominent, swollen over axial ribs; s1, s2, relatively strongly developed. Last whorl attaining ~75–80% of total height; rarely up to 85%; last whorl ovate with steep, straight-sided to weakly concave subsutural ramp, moderate shoulder angulation, weakly convex periphery, moderately constricted below. Axial sculpture of about ten moderately prominent axial ribs, weakening over base, fading over subsutural ramp. Spiral sculpture of weakly scabrose subsutural threads, adis, IP and abis of subequal strength, occasionally with weak tertiary threads intercalated; P1–P6, P6 on convex part of base, ADP, MP, ABP prominent and subequal is strength, rounded with wider interspaces along periphery, close-set on base; s1–s6 weaker but well developed; s4–s5 occasionally prominent. P1 forming indistinct, blunt tubercles on axial ribs. Growth lines forming weakly cancellate sculpture in spiral interspaces. Fasciole strongly swollen, twisted, delimiting broad, deep pseudoumbilicus. Aperture moderately small, ovate; outer lip strongly thickened, with crenulate edge; elongate denticles ID, D1–D6 within; D1, D4–D4 occasionally bifid, D6 usually bifid; anal canal moderately wide, distinctly incised; siphonal canal moderately long, narrow, fused, bent to the left, weakly recurved at tip. Columella broadly excavated, smooth, slightly angled at siphonal canal. Columellar callus forming broad rim, sharply delimited, weakly erect at siphonal canal, adherent in parietal area.

Discussion. Ocinebrinopsis credneri (Hoernes & Auinger, 1885) differs from its Paratethyan congeners in its larger size and the slightly coarser sculpture. It could be confused with Ocinebrinopsis dominicii sp. nov. but differs in its lower spire, less incised suture, shorter last whorl and its shorter and fused siphonal canal. Ocinebrinopsis orientalis (Friedberg, 1928) is smaller, slenderer and has a narrower aperture. Ocinebrinopsis credneri is slightly variable in shape but the paralectotype Fig. 30B View FIGURE 30 is an atypically stout specimen with a low spire. Ocinebrinopsis credneri is recorded from the Vienna Basin, Pannonian Basin, the Făget Basin and the Dacian Basin, but we are not aware of reliable records from northern Paratethyan basins.

Paleoenvironment. Unknown, probably shallow marine, inner neritic.

Distribution in Central Paratethys. Badenian (Middle Miocene): Vienna Basin: Borský Mikuláš ( Slovakia) ( Švagrovský 1982); Pannonian Basin: Letkés, Várpalota ( Hungary) ( Strausz 1966; Kovács et al. 2018); Bakony Mountains: Bánd ( Hungary) ( Kovács 2020); Făget Basin: Lăpugiu de Sus ( Romania) (Hoernes & Auinger 1885; Kovács 2019); Dacian Basin: Târnene ( Bulgaria) ( Nikolov 1994).
