Shell small (SL = 3.95—4.57 mm), thin, white, lanceolate conical, medium to high in profile (SH/SL = 0.35-0.46). Apex well posterior of center (P/SL = 0.74). Protoconch well below apex, 210 µm in length, with posteriormost portion enveloped by posterior slope of shell. Protoconch sculpture of raised cords forming even, hexagonal honeycomb pattern. Teleoconch sculpture dominated by 3 strong keels radiating from apex, 1 anteriorly directed keel situated along midline, 2 posteriorly directed keels each deviate from the midline by about 18°. Keels correspond to furrows along inner surface of shell. Numerous weaker radial cords present, concentric sculpture weak or indistinct. Anterior slope strongly convex, posterior slope straight, with concave trough between two posterior keels. Aperture with complex lanceolate outline, with convex areas flanking anterior keel. Shell edge thin. Periostracum thin, extending beyond shell edge, weakly hirsute along radial cords .

The lanceolate morphology of the shell, the presence of three strong keels, and the hexagonal honeycomb sculpture of the protoconch of this species are diagnostic. The Colombian specimens are larger and more variable in terms of shell height and apex position than specimens in the type series.

Previously known only from the type locality, off New Providence Island, Bahamas, at a depth of 518 m (McLean & Harasewych 1995). The present records extend the range to off the Caribbean coast of Colombia, and the depth to 292 m.
