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.
