Material.
Anda6 (1) RGM 1008316.
Characterization.
Shell medium-sized,
48 mm
. Protoconch multispiral, first whorls damaged, last whorl sculpted with radial ridges. Teleoconch whorls tuberculate. Spire of moderate height, stepped; outline slightly concave. Sutural ramp concave, ornamented with 1 increasing to 9 spiral grooves above the tubercles and with radial threads. Last whorl narrowly conical, outline straight to weakly convex at upper two-thirds and straight to weakly concave at lower one-third. However, the last whorl bears repaired break scars, which may influence its shape. Shoulder angulate, with small but persistent tubercles and three rather narrow spiral grooves just below tubercles. Subsutural flexure symmetrical, about as deep as wide. Sculpture of last whorl consists of many rather strong, axially striate spiral grooves. Siphonal canal deflected to the dorsal side. Aperture very narrow.
Distribution.
Taiwan
,
Philippines
and
Indonesia
(
Sulawesi
),
100–400 m
on mud (
Röckel, Korn & Kohn, 1995
). Also
Fiji
,
102–168 m
(
Moolenbeek, Röckel & Bouchet, 2008
) and
Philippines
,
100 m
(Raybaudi
Massilia, 2008
). Early Pleistocene of Timor (
Robba
et al.
, 1989
).
Remarks.
This specimen is different from typical
Conasprella pseudorbignyi
(
Röckel & Lan, 1981
)
in having stronger and persistent tubercles and stronger spiral grooves on the spire, but it matches this species in all other aspects.
Robba
et al.
(1989)
reported
Conus vimineus
Reeve,
1849 in
Ladd (1982)
and
C. insculptus
Kiener,
1847 in
Tesch (1915)
and in
Shuto (1969)
as
C. pseudorbignyi
(
Röckel & Lan, 1981
)
, but these shells are too high spired to be
C. pseudorbignyi (
Röckel & Lan, 1981
)
.
Puillandre
et al.
(2011)
argue that the
C. pseudorbignyi
(
Röckel & Lan, 1981
)
specimen in
Moolenbeek
et al.
(2008)
is morphologically closer to
C. joliveti
Moolenbeek, Röckel & Bouchet, 2008
. However, the specimen in
Moolenbeek
et al.
(2008)
differs from
C. joliveti
Moolenbeek, Röckel & Bouchet,
2008
in having coarser spiral cords on the body whorl and weaker tubercles on the spire, and in being relatively less high spired. Therefore, the specimen in
Moolenbeek
et al.
(2008)
is considered a typical
C. pseudorbignyi
(
Röckel & Lan, 1981
)
specimen here.
