Material examined: Solomon Islands, E of
San Cristóbal, 10°45'S, 162°20'E, 410-430 m, SO-LOMONBOA 3, st. CP2832, 1 lv (MNHN-IM-2009-18963).
Remarks. The species originally described from Pliocene of Timor was recorded also from Borneo, Celebes, the Philippines and the Maldives, in 464-1022 m [Powell, 1964; Sysoev, 1996]. Our single sequenced specimen has SL 25.5 mm, while Powell [1964] reported SL up to 33 mm.
Protoconch paucispiral, consists of about two smooth convex whorls. Transition to teleoconch is marked by appearance of median peripheral keel with nodules. Protoconch diameter 0.88 mm, height 0.75 mm.
Radula of marginal teeth only. Marginal teeth of modifíed duplex type, major limb pointed, medium broad, with thickened edges and depressed central portion, outer end (tooth base) poorly sclerotized. Accessory limb much narrower, although long and extends on outer edge beyond the limit of major limb. It is divided by deep longitudinal furrow along most of its length into two lobes, the inner lobe longer.
