Geographical distribution and bathymetry

New Caledonia: Norfolk Ridge, Loyalty Islands, and especially in the Coral Sea (Banks Nova, Argo, Kelso, Capel and Lansdowne), typically at depths between 200 and 500 m.

Remarks

Shell medium-sized to moderately large (maximum shell length 62 mm), conical, with a moderate, variably stepped spire of straight to concave profile. Early spire whorls tuberculated. Larval shell ( Fig. 65L ) multispiral of more than 3 whorls. Shoulder with a characteristic rounded ridge, often tuberculated in younger specimens. Base with a distinctive columellar plait, more evident in larger specimens. Color of the last whorl very pale violet to white, with sparse reddish brown dotted spiral lines. Radular tooth ( Fig. 65M ) elongated, with the anterior portion shorter than the posterior section. The tooth is serrated with more than 40 minute denticles arranged in multiple rows. Small, elongated terminating cusp present. Barb present. Blade rounded, covering about 66–75% of the anterior section of the tooth. Small basal spur on top of the base. In the phylogeny, all specimens of C. luciae form a clade deeply nested within the Kurodaconus clade. This species is particularly abundant on the southern banks of the Coral Sea, and it has not been found outside of the New Caledonia EEZ. Therefore, it is considered an endemism from this area.
