Terebra asulcoornata Sacco, 1891

Terebra acuminata Borson — Hoernes & Auinger 1880: 110, pl. 12, fig. 13 [non Terebra acuminata Borson, 1820 ].

* [ Terebra acuminatum] var. asulcoornata Sacc. — Sacco 1891a: 21 [pro Terebra acuminata Hoernes & Auinger 1880 : pl. 12, fig. 13].

Terebra (Terebra) acuminata var. asulcoornata Sacco, 1891 —Kojumdgieva in Kojumdgieva & Strachimirov 1960: 216, pl. 51, fig. 7.

Terebra nov. sp. — Bohn-Havas, 1973: 1129, pl. 8, fig. 12.

Type material. Holotype, SL: 70.5: mm, MD: 11.4 mm, Bujtur ( Romania); illustrated in Hoernes & Auinger (1880: pl. 12, fig. 13); the specimen was stored in the Geosphere Austria (formerly Geological Survey of Austria) but is lost. No additional material is available to us.

Revised description. Medium sized, slender, robust shell with slightly gradate spire, of up to 20 teleoconch whorls; apical angle 15°. Protoconch unknown. Subsutural band forming swelling with prominent, prosocline axial ribs and growth lines, indistinctly delimited by narrow concavity. Whorl profile subcylindrical below subsutural band, with weak, dense sigmoidal axial ribs. Last whorl about 22% of total height. Base strongly constricted. Fasciole prominent, broad, adapically delimited by narrow carina. Aperture unknown.

Discussion. This poorly known species falls in the “ magnoplicata -group” of Davoli (1977), which he defined for large, solid Terebra specimens with subobsolete subsutural groove and weak axial ribs. Without additional material it is impossible to decide if the Paratethyan specimens from Bujtur in Romania (illustrated by Hoernes & Auinger 1880) and from the Dobrusha in Bulgaria (illustrated in Kojumdgieva in Kojumdgieva & Strachimirov 1960) represent a distinct species or are aberrant shells of Terebra neglecta Michelotti, 1847 . Terebra magnoplicata ( Sacco, 1891a) , from the Langhian of Sciolze ( Italy), differs in its high last whorl and the nearly smooth and indistinct subsutural band (see Sacco 1891a: pl. 1, fig. 38; Davoli 1977: pl. 4, fig. 11).

Distribution in Central Paratethys. Badenian (Middle Miocene): Pannonian Basin: Pécsszabolcs ( Hungary) ( Bohn-Havas 1973); Făget Basin: Bujtur ( Romania) ( Hoernes &Auinger 1880); Dobrusha ( Bulgaria) (Kojumdgieva in Kojumdgieva & Strachimirov 1960).
