Geographical distribution and bathymetry

Japan to the Philippines, at depths between 200– 400 m. In New Caledonia it has been sampled at multiple localities (Coral Sea, Norfolk Ridge, Grand Passage area, Loyalty Islands), typically at depths between 200 and 400 m.

Remarks

Small conical shell (maximum shell length 25 mm) with a moderate to high spire of straight to slightly concave profile. Characteristic hollow spinose processes present at shoulder angle. Multispiral protoconch of about 3 whorls ( Fig. 82H View Fig ). Last whorl with spiral ribs, often granulated. Radular tooth ( Fig. 82M View Fig ) with the anterior section much shorter than the posterior section. Tooth serrated with 7–8 denticles arranged in one row, ending on a large, pointed cusp. Barb small. Blade pointed, covering about 60–70% of the anterior section of the tooth. Strong basal spur present on top of the very large base. In the phylogeny ( Fig. 2 View Fig ), C. (T.) chiangi is sister to C. (T.) polongimarumai . In the phylogeny of Phuong et al. (2019), C. (T.) chiangi appears sister to a clade which contains Indo-Pacific species included in the (sub)genus Rhombiconus Tucker & Tenorio, 2009 . The latter species are known to prey selectively on amphinomid polychaete worms.
