Material examined. None – the holotype is lost, Stn 196: Pacific, Western Central (Molucca Sea); 1508 m.

Supplementary descriptions. Newman & Ross (1971) and Chan et al. (2009).

Distribution. Pacific, Western Central and Southeast. Known depth range 1508 to 1965 m.

Habitat. On rocks and gastropod shells.

Remarks. Newman & Ross (1971) tentatively related this species to the Arcoscalpellum michelottianum group. In the absence of the holotype, a neotype designation may help to establish and stabilise the systematic position of this species.
