Revised description. Shell large, slender fusiform, with deeply incised suture. Protoconch (fig. 4O) high conical, of three smooth, convex whorls (height: 820 μm, diameter: 620 μm). Teleoconch of ten weakly convex to subcylindric whorls. Last whorl moderately convex, slowly contracting into high base. Some specimens with weak shoulder and faint angulation close below adapical suture, especially on penultimate and last whorls. Sculpture on spire whorls consisting of close-set, prominent, weakly opisthocline rounded axial ribs, separated by slightly narrower interspaces, crossed by close-set spiral cords, separated by narrow grooves, forming indistinct nodules at intersections with ribs, and distinct, flat cords in axial interspaces (about 20 axial ribs on penultimate whorl). Axial ribs crossed by subsutural spiral groove, delimiting weak subsutural band, most prominent on early teleoconch whorls. Subsutural band often disintegrating into narrow spiral cords during growth. Axial ribs slightly more widely spaced on last three whorls. Axial and spiral sculpture often reduced on last whorl. Spiral cords more wide-spaced on base and fasciole. Aperture narrow, elongate; columellar callus narrow, weakly delimited, bearing four prominent columellar folds, weakening abapically. Outer lip thin, without lirae in adult specimens; delicate lirae deep inside aperture only in subadult specimens. Siphonal canal long, moderately narrow, straight, with shallow siphonal notch.
Shell measurements and ratios. SL: 20.1–42.0 mm, MD: 5.8–12.8 mm; AA: 25–35°, SL/MD: 3.3–3.6, AL/ AW: 5.0–5.8, AH/S: 1.9–2.1.
Discussion. This species was identified as Vexillum cupressinum (Brocchi, 1814) by all authors dealing with Paratethyan mollusc faunas until Bałuk (1997) separated it as Vexillum pseudocupressinum. Bałuk (1997) stressed the more densely spaced axial ribs and higher number of spiral cords being restricted to the axial interspaces. Landau et al. (2013) doubted if these features justify a separation, referring to the high variability in sculpture in late Miocene and Pliocene populations of Tosapusia cupressina, as documented by Pelosio (1967), Malatesta (1974), Davoli (2000), Chirli (2002) and Chirli & Richard (2008). After having studied a large number of Paratethyan specimens, we agree with Bałuk (1997). Despite the variability of T. cupressina, it differs constantly by its lower number of axial ribs (especially on early spire whorls). Its spiral cords are less numerous and form a cancellate or nodulous pattern with the axials ribs, lacking the deeply cut grooves seen in the axial interspaces in T. pseudocupressina. Moreover, the Paratethyan species is nearly twice as large as T. cupressina and it lacks the twisted siphonal canal of the Pliocene species. Note that the specimen illustrated by Hoernes & Auinger (1880, pl. 10, fig. 10) with strongly deflected siphonal canal is a pathological specimen with healed fractures.
Palaeoenvironment. The species is most abundant in clay of the Baden Formation suggesting middle neritic settings with up to 250 m water depth (Hohenegger et al. 2008).
