Geographical distribution and bathymetry

Japan to the Philippines, at depths between 120‒ 250 m. In New Caledonia it has been sampled in several locations in Norfolk Ridge, Grand Passage, and also in Loyalty Ridge, at depths of 100‒ 400 m. Also reported from Fiji in 416 m ( Moolenbeek et al. 2008), and Wallis & Futuna Islands in 290‒400 m (Moolenbeek & R̂ckel 1996).

Remarks

Small shell (maximum shell length 23 mm), narrowly conical to conical, with a low to moderate spire of concave outline. Protoconch multispiral of 3.5–3.75 whorls ( Fig. 25D ). Radular tooth ( Fig. 25M ) with a short barb, a pointed blade, and a very well developed, pointed posterior blade. The anterior section of the tooth is much shorter than the posterior section. Shaft fold present. A basal spur is present on top of the slanted base.
