Geographical distribution and bathymetry

Distributed around New Caledonia, Loyalty Ridge and in the Coral Sea, typically at depths between 200 and 400 m. It also seems to be present in the Philippines and Vanuatu ( Puillandre et al. 2011).

Remarks

Medium-sized (maximum length 57 mm) narrowly conical shell, with a high spire. Protoconch ( Fig. 45L ) of 3 or more whorls, smooth, glossy and translucent. Last whorl white or sparsely patterned with 3 spiral bands of irregular brown blotches. Radular tooth ( Fig. 45M ) small, with a barb, a pointed blade, and a pointed posterior blade. The anterior section of the tooth is much shorter than the posterior section. Shaft fold present, blunt at its anterior end. Basal spur is present on top of the slanted base. Although originally introduced as a subspecies of Conasprella (Fusiconus) orbignyi ( Audouin, 1831) , C. coriolisi is a distinct species. In the phylogeny ( Fig. 2 ) all specimens of C. coriolisi form a clade which is sister to C. comatosa , with a genetic distance to typical C. orbignyi of approximately 9% ( Puillandre et al. 2011).
