As Buccinofusus surinamensis:

Shell is solid, oblong fusiform, in outline. Protoconch is eroded but seemingly mamillate. Teleoconch whorls are 7.5 in number of turns, long, weakly inflated with shallowly constricted sutures. External surface of the shell is white, rather chalky, but covered with dark brownish yellow periostracum which is feebly raised at growth lines, and is ornamented by axial ribs and spiral cords overriding the former. Axial ribs are almost straight but weakly opistho-cline and indistinct on the sutural ramp but emphasized on the shoulder at around two-fifths posterior on each whorl. They are about 17 on the penultimate whorl. On the body whorl, 10 are recognized as axial ribs and afterwards they diffuse with growth lines that become irregular plicae. Spiral cords are rather regular, they are subequal in strength and subequally spaced, despite those in the middle portion of each whorl are more prominent than those below and above. There are some intercalated ones here and there. Numbers of spiral cords are about 16—18 on the penultimate whorl, while more than 40 on the body whorl including those on the base and neck where axial sculptures entirely diminish.
Aperture is oblong fusiform and siphonostomalous. The outer lip is smooth but weakly constricted at basal lip and near the posterior corner forming an acute anal sulcus. At the posterior constriction, the margin of the outer lip is slightly concave. The inner wall of the outer lip is white and ornamented with crowded spiral costae that terminate at a short distance behind the lip margin. The parietal to columellar margins curve in a gentle sigmoid. The callus entirely reflects over the siphonal fasciole sealing the umbilicus. There is a very weak columellar fold (or just a step created by early siphonal fasciole that was completely covered by columellar callus). This area has a pale orange hue despite other internal area is mostly white with a slight hint of pinkish hue. The siphonal canal is moderately long, slightly twisted backwards and open with a round tip. Operculum and animal were not preserved. Shell length 85.0 mm, breadth 27.0 mm.

The present new species somewhat resembles a volute, Fusivoluta anomala (Martens, 1902) from east Africa, but it is decidedly a non-volute because of small protoconch (even eroded) and thick outer lip within which spiral costae present. There seems no comparable species in the same zoo-geographical area.
