PHILIPPINES • 34 mm; ER coll. (Fig. 43L).

Geographical distribution and bathymetry

Japan, Philippines, NW Australia, Solomon Islands and Vietnam, at depths between 80‒ 400 m. Widely distributed around New Caledonia, Loyalty Ridge and in the Coral Sea, typically at depths between 200 and 400 m.

Remarks

Shell narrowly conical, moderately small to medium-sized (maximum length 50 mm), with a moderate to high spire. The dark brown color of the anterior end of the body whorl is a distinctive character for this species. Protoconch (Fig. 43H) multispiral of about 3.5 whorls. Radular tooth (Fig. 43L) small, with a barb, a pointed blade, and a very small pointed posterior blade, difficult to detect. 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. Specimens from New Caledonia are similar in morphology to those from Japan and the Philippines. In the phylogeny (Fig. 2), the only specimen sequenced appears sister to Bathyconus coriolisi .
