DISTRIBUTION. — Indo-West Pacific, from the eastern coast of Africa ( Kenya and Mayotte) to Maldives, Papua New Guinea, Philippines, New Caledonia and French Polynesia ( Pizzini & Raines 2011; Pizzini et al. 2013; Vannozzi 2017; 2019b; unpublished data).

DIAGNOSIS. — Shell of average size for the genus. Tube smooth, tapering toward the apex. Aperture simple, inclined, preceded by a slight but distinct swelling on the ventral side. Microsculpture of fine longitudinal striae interrupted by growth lines. Macula small, white, heart-shaped. Septum protruding, with a strong, ear-like mucro rotated toward the right side. Juveniles thin, conical and curved, Transition to the adult stage rapid. Length about 2 mm.

REMARKS

This species shows a very wide distribution in the tropical Indo-West Pacific but is never abundant. A small heart-shaped white macula observed in the ventral side of the tube in adult shells is characteristic of this species.
