Genus Striopusionella nov. gen.

Type species. Clavatula szekelyhidiae Kovács & Vicián, 2021 ; middle Miocene (Badenian, Langhian), Hungary, Central Paratethys Sea .

Etymology. Combination of Strio - (Latin, referring to the striate sculpture) and Pusionella .

Diagnosis. Moderately large, solid, moderately slender fusiform shell with tripartite early teleoconch whorls, weakly concave whorls, insignificant subsutural collar, dense spiral sculpture, weak shoulder and wide and very shallow anal sinus.

Description. As for the type species.

Stratigraphic and geographic range. Middle Miocene (Badenian, Langhian), Central Paratethys Sea, Hungary.

Included species. Monotypic.

Paleoenvironment. Inner neritic environments.

Discussion. The type species was placed in Clavatula by Kovács & Vicián (2021). The slender conical spire and the peculiar spiral sculpture along with the extraordinarily shallow anal sinus, however, exclude a placement in Clavatula . Similarly, Megaclavatula nov. gen., Granulatocincta nov. gen. and Olegia nov. gen. differ from Striopusionella by their significantly deeper anal sinus. Pusionella Gray, 1847 develops a comparable anal sinus, but the concave spire whorls and the peculiar spiral sculpture contradict a placement in Pusionella . Moreover, Pusionella has opisthocline beads along the abapical suture on early teleoconch whorls. Striopusionella nov. gen. combines an unusual set of shell characters, and placement within the informal Clavatula group or Perrona group is unclear. However, the very shallow anal sinus is shared only with the genus Pusionella in the Perrona group, and we place it close to that genus herein.
