Revised description.
Shell medium-sized, moderately broad fusiform with high, weakly gradate spire; apical angle 35–38°. Protoconch high conical, only partly preserved consisting of two high weakly convex whorls. Teleoconch of 11 whorls. Early teleoconch whorls with weak subsutural spiral cord and suprasutural row of large, slightly opisthocline beads, separated by broad concave mid-whorl portion. On third to fourth whorl profile flatsided, suprasutural beads fade, narrow groove separates narrower subsutural cord from wider abapical portion of whorl. Late whorls smooth, subcylindrical. Suture weakly impressed, linear. Last whorl about 55% of total height. Subcylindrical subsutural collar; ramp and shoulder not developed. Rounded and moderately constricted at base. Siphonal fasciole strongly delimited by raised ridge, flattened, twisted, with prominent growth lines. Sculpture of weak, narrow cords restricted to base and fasciole. Aperture moderately wide, pyriform. Outer lip thin, smooth within. Anal sinus very shallow, wide; siphonal canal moderately long, strongly deflected to left and dorsally, very deeply notched at tip. Columella weakly twisted, smooth. Columella excavated in upper third, strongly twisted at fasciole. Columellar and parietal callus thin, poorly delimited from base.
Discussion.
Pusionella pseudofusus
(
Des Moulins, 1842
)
from the Burdigalian of the northeastern Atlantic differs in its slightly more convex whorls, the less subcylindrical last whorl, the less constricted base and the weaker spiral cord delimiting the fasciole (see
Peyrot 1931: 103
, pl. 9, figs 74–76, https://commons.wikimedia.org/wiki/
Pusionella
_pseudofusus#/media/File:
Pusionella
_pseudofusus_01.JPG).
Pusionella tauronifat
Sacco, 1891
differs from
P. palatina
Strausz,
1954
in its lower spire, the higher, barrel-shaped last whorl and the slightly angulated base (see
holotype
in
Sacco 1904: 62
, pl. 2, fig. 77 and
Ferrero Mortara
et al.
1984: 66
, pl. 56, fig. 14).
Pusionella pedemontana
Sacco, 1891
is based on
two syntypes
, which are most probably not conspecific. Both specimens can be distinguished easily from
P. palatina
:
syntype
BS.033.01.001 has a much higher and markedly gradate spire (see
Ferrero Mortara
et al.
1984
, pl. 56, fig. 12) and
syntype
BS033.01.002 has convex whorls and a higher last whorl (see
Ferrero Mortara
et al
. 1984
, pl. 56, fig. 13). To clarify the situation, we designate specimen BS033.01.002 from the Burdigalian of Baldissero (
Italy
) as
lectotype
of
Pusionella pedemontana
Sacco, 1891
.
Pusionella borealis
Kautsky, 1925
is distinguished from all other Miocene
Pusionella
species
by its prominent spiral sculpture (
Kautsky 1925: 151
, pl. 10, figs 24–25).
Paleoenvironment.
Extant
Pusionella
species
occur in inner neritic environments, e.g.,
Boyer & Ryall (2006)
report
Pusionella ghanaensis
from
18 to 34 m
water depth. This agrees with the occurrence of
P. palatina
at Várpalota, which represents an agitated coastal setting with sand bottoms (own data).
Distribution in Central Paratethys.
Badenian (middle Miocene):
Pannonian Basin.
