Material examined

3 lots (3 specimens). See Supp. file 1.

Type material

Holotype TAIWAN • 53 mm; near Tiao-yu-tai, NE Taiwan ; 75 m depth; TMGS.

Figured material

NEW CALEDONIA • 41.2 mm; Loyalty Basin , off New Caledonia, stn DW253; 21º32′ S, 166º20′ E; 310‒315 m depth; 16 Apr. 1987; BIOGEOCAL expedition; MNHN ( Fig. 5F ) .

Geographical distribution and bathymetry

Taiwan, Philippines and Solomon Islands. In New Caledonia, Coral Sea (W Bellona) and Loyalty Basin, dead collected at depths between 300 and 600 m. Several specimens collected at depths of 300‒900 m during the TARASOC expedition to the central island groups of French Polynesia (Tuamotu Atolls) were identified as P. lani by Rabiller & Richard (2014). These were considered juvenile individuals, but might actually correspond to another, yet undescribed species which requires further studies.

Remarks

This is a medium-sized species, only represented from New Caledonia by one dead collected specimen and one fragment of another one. It has not been studied using DNA and its radular morphology is unknown, so its assignment to the genus Profundiconus is only provisional.
