Material examined 1 lot ( 1 specimen ). See Supp. file 1. Type material Holotype JAPAN • 72.5 mm ; off Tosa ; 110–128 m depth ; THTA . Figured material NEW CALEDONIA • 40.5 mm ; Grand Passage , off New Caledonia , stn DW2985; 18°59′ S , 163°06′ E ; 277‒289 m depth ; 5 May 2008 ; CONCALIS expedition; MNHN ( Fig. 61D ) . TAIWAN • 68.7 mm ; MJT coll. ( Fig. 61K ). Geographical distribution and bathymetry Japan to Taiwan and the Philippines . This is the first record from New Caledonia , where one single specimen was sampled in the Grand Passage area, at depths between 277‒ 289 m . Remarks Shell moderately large to large (maximum shell length 100 mm ), ventricosely conical to broadly and ventricosely conical, with a high, stepped spire of straight profile. Early spire whorls tuberculated. Shoulder subangulate to rounded. Color of the last whorl white or pale violet, with spiral rows of brown spots. Radular tooth ( Fig. 61K ) very elongated, with the anterior portion of about equal length as the posterior section. The tooth is serrated with about 40 minute denticles arranged in two rows, ending on a small, pointed terminating cusp. Barb small. Blade rounded, covering about 40% of the anterior section of the tooth. Small basal spur on top of the base. The radular analysis is based on a specimen from Taiwan , as no live specimens were sampled from New Caledonia . For this reason, it was not included in the phylogeny. This is a species very similar to C. ( K. ) stupa . However, apart from the differences in shell pattern, the very different radular morphologies suggests that C. ( K. ) stupella and C. ( K. ) stupa are not synonyms of each other, as it has often been considered.
