Revised description. Shell moderately large, moderately slender fusiform, with high, slightly gradate spire. Protoconch (Fig. 4J) multispiral, high conical of 3.5 smooth, nearly straight-sided whorls (height: 940 μm, diameter: 750 μm). Teleoconch of about eight subcylindrical to weakly convex whorls, separated by narrowly impressed suture. Axial sculpture of close-set orthocline ribs separated by slightly narrower interspaces (about on 20 penultimate whorl). Last whorl strongly constricted. Axial sculpture on last whorl often reduced. Aperture wide, ovoid with indistinct anal canal. Columellar callus indistinct, barely delimited from base. Columella with four oblique columellar folds, weakening abapically. Outer lip convex, thin, with 10–12 long delicate lirae placed deep within aperture. About five weak to prominent spiral cords on weak fasciole, partly extending from columellar folds. Siphonal canal moderately short, bent slightly to left, with shallow siphonal notch.
Shell measurements and ratios. SL: 10.2–16.0 mm, MD: 3.6–5.0 mm; AA: 32–40°, SL/MD: 2.8–2.9, AL/AW: 3.0–3.9, AH/S: 2.5–2.7.
Discussion. Hoernes & Auinger (1880) identified this species as Mitra recticosta, which was described by Bellardi (1850) from the Pliocene of Italy. Bellardi (1887b) doubted this identification and separated the Viennese shells based on their smaller size, more numerous and narrower axial ribs and the shorter last whorl from his M. recticosta but did not propose a new name. This was done by Boettger (1906) who introduced Mitra pseudorecticosta as new name. It is important to note that although Boettger (1906) described specimens from Coşteiu de Sus (Romania), he clearly referred to the Austrian specimens illustrated by Hoernes & Auinger (1880), when introducing Mitra pseudorecticosta as new name. Curiously, the specimens from Coşteiu de Sus, which Boettger (1906) had at hand when discussing Mitra pseudorecticosta are not conspecific with the Austrian shells and are described here as Pusia confunda nov. sp. Friedberg (1910), who was unaware of Boettger’s paper, introduced Mitra dubia as new name for Mitra recticosta Hoernes & Auinger, 1880. This name, however, was preoccupied by Hutton (1873) and therefore, Friedberg (1911) proposed Turricula vindobonensis as replacement name a year later. Boettger (1906) and Friedberg (1910, 1911) refer to the same lot of illustrated specimens and therefore, Turricula vindobonensis is an objective junior synonym of Mitra pseudorecticosta Boettger, 1906. The placement of this species in Pusia is tentative.
Hölzl (1973: 93) mentioned Vexillum (Costellaria) vindobonense (Friedberg) from the Ottnangian (middle Burdigalian) of Kaltenbachgraben in Bavaria. This would be the oldest record of this group from the Paratethys Sea.
Palaeoenvironment. Most abundant at localities suggesting silty-sandy inner neritic environments partly with sea grass meadows (e.g. Steinebrunn) (own data).
Distribution in Central Paratethys. Badenian (middle Miocene): Korytnica Basin: Korytnica (Poland) (Bałuk 1997); Ukrainian Fore-Carpathian Basin: Dryszczów (Nadrichne), Zborów (Zboriv) (Ukraine) (Friedberg 1911); Vienna Basin: Niederleis, Steinebrunn (Hoernes & Auinger 1880), Sedlec (= Porzteich) (Czech Republic); Eisenstadt-Sopron Basin: Forchtenau (Hoernes & Auinger 1880).
Eastern Paratethys. Tarkhanian (early Middle Miocene) of Tomakivka (S. Ukraine) (Mikhailovsky 1903). Proto-Mediterranean Sea. Karaman Basin: Seyithasan (Turkey) (Landau et al. 2013).
