Revised description.
Medium-sized, ovate shell; apical angle 63°. Protoconch unknown. Teleoconch of at least four whorls. Suture distinctly incised, linear. Early teleoconch whorls moderately convex with rounded shoulder. Spiral sculpture of very broad, strap-like, rounded IP, P1 and P2 separated by narrower interspaces on antepenultimate and penultimate whorls. No axial sculpture except for narrow growth lines forming cancellate pattern in spiral interspaces. Last whorl ovate with convex periphery, moderately constricted below. Very broad,
band-like IP, P1–P6, ADP and narrow s1 with deep, narrow interspaces. P1 only slightly more prominent. Fasciole moderately swollen; narrow pseudoumbilicus covered by columellar callus. Aperture wide, ovate; outer lip not thickened (margin missing) with blunt D1–D5 placed some distance behind peristome. Anal canal wide, poorly delimited. Siphonal canal moderately short, wide, open, slightly bent to the left. Columella broadly excavated, smooth. Columellar callus thin, adherent, poorly delimited from base.

Discussion.
Extent
Haustrum
species
occur in the south Pacific. Therefore, its occurrence in the Circum-Mediterranean Neogene would be surprising but
Haustrum pyrulatum
(Hoernes & Auinger, 1882)
is strikingly similar to the extant
Haustrum lacunosum
(
Bruguière, 1789
)
from
New Zealand
(
Figs 2B
1
–B
2
). Both species differ from each other only by the narrow s
1 in
Haustrum pyrulatum
.
Haustrum pyrulatum
was originally placed in
Polytropa
Swainson, 1840
by Hoernes &Auinger (1885), which is a junior synonym of
Nucella
Röding, 1798
[
type
species
Nucella lapillus
(
Linnaeus, 1758
)
], subsequent designation by
Stewart (1927: 386)
; present-day, northern Atlantic]. Indeed,
Haustrum pyrulatum
is also reminiscent of the
Ocenebrinae
genus
Nucella
.
Nucella
species
differ from
Haustrum pyrulatum
in their narrower primary cords and the more prominent secondary cords, which are often equal to the primary cords in strenght. Moreover,
Nucella
is a cool-temperate genus, which originated during the late Middle Miocene in the Pacific and spread to the Atlantic around 6.2 my ago (
Marko
et al.
2014
). Therefore, a close relation of the Paratethyan species with
Nucella
is unlikely.
Spinucella
Vermeij, 1993
[
type
species
Purpura tetragona
J. de C. Sowerby, 1825, original designation by
Vermeij (1993: 20)
; Pliocene, North Sea] occurred also in the warmer Proto-Mediterranean waters during the Miocene and Pliocene (
e.g.
,
Spinucella monocanthos
(
Brocchi, 1814
)
,
S. cancellata
(
Bellardi, 1882
)
,
S. depressa
(
Bronn, 1831
)
but these species usullay have a more or less shouldered last whorl and differ from
Haustrum
in their narrower spiral cords and the presence of axial ribs (see
Bellardi 1882
: pl. 12, figs 1–3). Although we note the problem of a Paratethyan distribution of an otherwise south Pacific genus, we tentatively place this species in
Haustrum
with questionmark. However, it might represent a striking example of convergence.
