Geographical distribution and bathymetry
New Caledonia
, Coral Sea and
New Hebrides
Arc including
Vanuatu
, typically at depths between 300 and
600 m
.
Also reported from
Fiji
at depths of
390‒405 m
(
Moolenbeek
et al.
2008
).
Remarks
Small to medium-sized (maximum shell length
30 mm
) conical shell with a carinate shoulder and moderately high spire of concave outline. Protoconch multispiral of about 3 whorls (
Fig. 34L
). Teleoconch sutural ramp with strong radial threads. There are 3 or 4 closely-set punctate spiral grooves just below the shoulder. Other than this, the last whorl can be essentially smooth, or variably covered with wide, axially striate spiral grooves. The typical shell pattern consists of about 6–8 broad brown spiral lines on the ribbons between the basal spiral grooves, but certain specimens also display interrupted brown bars and dashes or irregular brown blotches on the lavender-white area above the basal third. Radular tooth (
Fig. 34M
) with an indistinct 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 slanted base. This is a relatively abundant species in deep water around
New Caledonia
. In the phylogeny (
Fig. 2
), all the sequenced specimens of
C. boucheti
form a well-supported clade which is sister to the other species of
Conasprella
.
