Pusia moravica Harzhauser & Landau 2021, nov. comb.

Description

Pusia moravica (Hoernes & Auinger, 1880) nov. comb.

Figs 13I 1 –I 2, J

* Mitra plicatula Var. (moravica)— Hoernes & Auinger 1880: 84.

Type material. Lectotype (designated herein): NHMW 1862 /0029/0006, SL: 9.8 mm, MD: 4.7 mm, Rudice (Czech Republic), figs 13I 1 –I 2. Paralectotype: NHMW 2020 /0097/0001, SL: 12.6 mm, MD: 6.5 mm, Rudice (Czech Republic), fig. 13J.

Revised description. Shell moderately large, stout fusiform, with slightly gradate spire. Protoconch and early teleoconch unknown. Teleoconch whorls low, weakly convex, with periphery in abapical third; suture impressed. Sculpture of sharp crested, orthocline to weakly prosocline ribs, separated by interspaces of about same width (about 15 axial ribs on penultimate whorl). Adapical weak subsutural spiral groove cuts ribs, forming narrow subsutural spiral cord of weak nodes. Further delicate spirals placed below subsutural cord, abapically rapidly weakening. Last whorl convex with short, moderately constricted base. Axial ribs becoming subobsolete on last whorl. Columella with four prominent, oblique columellar folds. Siphonal canal moderately long, straight.

Shell measurements and ratios. SL: 9.8–12.6 mm, MD: 4.7–6.5 mm (fragments; restored height: 13–16 mm); assumed SL of complete specimen: 18 mm, AA: 33°.

Discussion. Only two fragments are available, which Hoernes & Auinger (1880) described as variety of “ Mitra plicatula ” (= Vexillum transalpinum nov. sp.). A close relationship between Pusia moravica (Hoernes & Auinger, 1880) and V. transalpinum, however, is unlikely in respect to the short spire whorls and broad, convex last whorl of P. moravica. In addition, the subsutural spiral row of weak nodes and the presence of spiral grooves allows a clear separation from V. transalpinum.

Palaeoenvironment. The specimens derive from basinal clay, suggesting a middle neritic depositional environment.

Distribution in Central Paratethys. Badenian (middle Miocene): Vienna Basin: Rudice (Czech Republic) (Hoernes & Auinger 1880).
