Geographical distribution and bathymetry

New Caledonia: Norfolk Ridge and Loyalty Islands, typically at depths between 100 and 300 m. Some specimens have been sampled in the Coral Sea (Bellona Plateau) and the New Hebrides Arc (Hunter Island). The species has not yet been found outside of the New Caledonia EEZ, and therefore it can be considered endemic.

Remarks

Shell small to moderately small (maximum shell length 30 mm), broadly conical, with a moderately stepped, nodulose spire of deeply concave profile. Larval shell ( Fig. 63L View Fig ) multispiral of more than 4 whorls. Shoulder slightly tuberculate to carinate. Last whorl pure white-colored, smooth or with granulated spiral ribs ( Fig. 63F–H, K View Fig ). Radular tooth ( Fig. 63M View Fig ) with the anterior section much shorter than the posterior section. The tooth is serrated with 12–15 minute denticles arranged in two rows. The denticles are obsolete or absent in the apical portion. Small, almost indistinct rounded terminating cusp present. Barb small, rather indistinct. Blade rounded, covering most of the anterior section of the tooth. Basal spur on top of a narrow base. In the phylogeny ( Fig. 2 View Fig ), the specimens of C. (K.) gondwanensis form a clade sister to the other species of Kurodaconus .
