Type material. Lectotype (designated herein): NHMW 2023 View Materials /0357/0002, SL: 3.2 mm, MD: 1.5 mm, Perchtoldsdorf ( Austria); illustrated in Fuchs in Karrer (1877: pl. 16a, fig. 2), Figs 49A View FIGURE 49 1 –A View FIGURE 1 2 View FIGURE 2 .

Illustrated material. NHMW 1868/0051/0009, SL: 3.6 mm, MD: 1.8 mm, illustrated in Hoernes & Auinger (1890: pl. 31, fig. 11), Perchtoldsdorf ( Austria), Fig. 49B View FIGURE 49 .

Discussion. This tiny species was placed in Euthria by Hoernes & Auinger (1890), which was followed by subsequent authors. The large protoconch with the characteristic sculpture of delicate axial ribs is typical for the columbellid genus Bellacolumbella Harzhauser & Landau, 2021 . Bellacolumbella immatura differs from congeneric species described by Harzhauser & Landau (2021) and represents an additional species in this genus, which was overlooked by Harzhauser & Landau (2021) in their revision of the Paratethyan Columbellidae .

Distribution in Central Paratethys. Badenian (Middle Miocene): Vienna Basin: Perchtoldsdorf ( Austria) (Hoernes & Auinger 1890); Pannonian Basin: Szob ( Hungary) ( Strausz 1966a).
