Revised description. Shell moderately large, moderately slender fusiform, with high spire. Protoconch (fig. 4K) high conical of 3.5 smooth, weakly convex whorls (height: 900 μm, diameter: 720 μm). Teleoconch of six to seven weakly convex to subcylindrical whorls, with periphery close above abapical suture; suture deeply incised. Sculpture comprising prominent, weakly opisthocyrt axial ribs, separated by interspaces of roughly equal width. Axial ribs often slightly swollen at adapical tip, resulting in weakly gradate spire. Delicate spiral cords restricted to interspaces between axial ribs. Axial ribs slightly broader on last whorl. Last whorl slightly inflated, evenly convex, strongly constricted at base. Aperture wide, ovoid, with indistinct anal sinus. Columellar callus narrow, sharply delimited. Columella with three prominent folds, weakening abapically; very weak fourth fold in some specimens. Outer lip thin, bearing about ten delicate lirae within. About four weak spiral cords on base. Siphonal canal short, bent slightly to left, with shallow siphonal notch.

Shell measurements and ratios. SL: 8.4–12.9 mm, MD: 3.3–4.9 mm; AA: 33–35°, SL/MD: 2.7–3.0, AL/AW: 2.2–3.5, AH/S: 3.0–4.5.

Discussion. This species was originally identified by Hörnes (1852b) as Mitra recticosta Bellardi, 1850, which lacks spiral sculpture. Consequently, Hoernes & Auinger (1880) identified it as Uromitra borsoni Bellardi, 1850, based on the rather schematic drawings in Bellardi (1850). Meznerics (1933) doubted this identification and described the specimens from Steinebrunn as new species. This view is supported by the illustration of a syntype of Vexillum borsoni (Bellardi, 1850) from the Tortonian S. Agata (Italy) (Ferrero-Mortara et al., 1981, pl. 52, figs 14a–b). It differs from the Austrian species in its sigmoidal axial ribs, the strongly constricted base and the longer siphonal canal.

Pusia schafferi was also mentioned from the Ottnangian (Burdigalian) of Bavaria (Kaltenbachgraben) by Steininger (1973) based on a spire fragment. The specimen has never been illustrated and the identification remains unclear.

Pusia schafferi (Meznerics, 1933) has a similarly elongated fusiform shape as P. pseudorecticosta (Boettger, 1906), but differs in having fine spiral grooves visible in the axial interspaces, whereas in P. pseudorecticosta only the strong spiral cords over the siphonal fasciole are present.

Palaeoenvironment. Steinebrunn represents a silty-sandy inner neritic environment with sea grass meadows (own data).
