Geographical distribution and bathymetry
New Caledonia
: Norfolk Ridge and Grand Passage area, Loyalty Ridge and Coral Sea (Lansdowne Bank and Bellona Plateau), typically at depths between
200–500 m
(
Fig. 24
). This species can be considered endemic.
Remarks
Conical shell small to moderately small (maximum length
30 mm
), slightly pyriform. Protoconch (
Fig. 23L
) multispiral, pointed, of 4.5–5 whorls. Protoconch white with a peculiar brown blotch on fourth whorl. Spire slightly stepped, of moderate height, with a slightly convex outline. Radular tooth (
Fig. 23M
) large, very elongated with an extremely long anterior section that is more than four times as long as the posterior section of the tooth. Barb small and indistinct, with a blade that is enlarged and widened laterally. Serrations absent. Waist indistinct. Shaft fold not well developed but present. Slanted base with a large basal spur. This is one of the most abundant deep-water species of
Conidae
in
New Caledonia
. In spite of its large multispiral protoconch, the species can be considered endemic. It is highly variable in pattern and color. Pustulose specimens (
Fig. 23I
), with a somehow weird aspect, are not uncommon, but their identification is often confusing. In the phylogeny (
Fig. 2
), the specimens of
C. alisi
sequenced form a clade sister to
Conasprella
cf.
pseudokimioi
.
