Geographical distribution and bathymetry
Ryukyu Islands
and the
Philippines
at depths between
120–
380 m
. In
New Caledonia
the species has been sampled mainly at
Norfolk
Ridge, but also at the
Loyalty Islands
, the Grand Passage area and the Coral Sea (Lansdowne Bank) at depths between 100 and
400 m
.
Some isolated specimens come from more than
700 m
deep. The species has also been cited from
Wallis
&
Futuna
(Moolenbeek & R̂ckel 1996) and Polynesia (
Rabiller & Richard 2014
).
Remarks
Shell small to moderately small (maximum shell length
25 mm
), conical, with a moderate, slightly stepped spire of concave outline. Protoconch multispiral of 3.25 to 3.5 whorls (
Fig. 28L
). Radular tooth (
Fig. 28M
) small, with a barb and a pointed blade covering about one third of the anterior section, which is much shorter than the posterior section. Shaft fold present. Basal spur is present on top of the large, slanted base. Specimens from
New Caledonia
are morphologically similar to those from the
Philippines
. One specimen from this locality has been sequenced, and it appears sister to other species of
Conasprella
in the phylogeny (
Fig. 2
). No specimens of
C. aphrodite
from
New Caledonia
have been sequenced.
