Revised description.
Small shells with moderately low conical spire; early spire with beaded carina. Late spire whorls smooth, deeply concave near upper suture and with prominent rim at lower suture; suture narrowly incised. Subsutural flexure of medium depth, strongly curved, moderately asymmetrical. Last whorl elongate conical, slightly constricted at base. A few deep and broad spiral grooves are restricted to the base. Siphonal fasciole very weak. Aperture largely destroyed; no information on colour patterns.
Shell measurements and ratios.
n = 7: largest specimen (fragmented): MD:
16.1 mm
, mean SL:
23.9 mm
(σ = 1.9), mean MD: 12.7 (σ = 1.0), spire angle: µ = 100.1° (σ = 5.7°), last whorl angle: µ = 33.7° (σ = 1.1°), LW: µ = 1.89 (σ = 0.06), RD: µ = 0.66 (σ = 0.02), PMD: µ = 0.9 (σ = 0.04), RSH: µ = 0.21 (σ = 0.02).
Discussion.
We do not follow
Hall (1966)
, who synonymised
Conus allioni
with
Conus brocchii
Bronn, 1828
.
Conilithes brocchii
is a Pliocene species, which differs in its larger size, higher and sometimes slightly coeloconoid spire, prominent sutural ridge and the broader last whorl, lacking the slight constriction of
C. allioni
, which has a low and sometimes cyrtoconoid spire.
Conus raulini
Peyrot, 1931
, based on a specimen from the Burdigalian of the
Aquitaine
Basin, is most probably a subjective junior synonym of
Conus allioni
.
This species was introduced by
Michelotti (1847)
as
Conus Allioni
. Therefore
, the prevailing use as
Conus allionii
is an incorrect subsequent spelling.
Paleoenvironment.
The Kleinebersdorf section represents coastal mudflat environments with
Avicennia
- mangroves (
Zuschin
et al
. 2004
).
Distribution in Paratethys.
? Ottnangian (early Miocene):
North Alpine Foreland Basin
: Bad Tölz (
Germany
) (
Steininger 1973
); Karpatian (early Miocene):
Korneuburg Basin
: Kleinebersdorf (
Austria
).
Proto-Mediterranean Sea and
North eastern Atlantic.
Burdigalian (early Miocene):
Aquitaine
Basin
: Saint- Jean-de-Marsacq, Saubrigues (
France
) (
Peyrot 1931
); Turin Hills: Baldissero, Valle Ceppi (
Italy
) (
Sacco 1893a
;
Zunino & Pavia 2009
). Occurrences from the early and middle Miocene of the
North Sea Basin
, mentioned by
Beyrich (1853)
and
Kautsky (1925)
seem to represent another species (see
Janssen 1984
).
