Diagnostic characters. Ovately fusiform shell; spire whorls angular at the adapical third; aperture elongate; wide siphonal canal; shallow C-shaped anal sinus; 13–15 slightly opisthocline axial ribs per whorl; fine spiral threads (2 per whorl); pointed nodes at the intersection of ribs and threads; dense microsculpture of spiral rows of granules throughout. Protoconch: low conical; 3.6-3.7 whorls; diameter about 860 µm (protoconch I: 270 µm); height about 1000 µm; first 1.25 whorls (protoconch I; transition to protoconch II undefined) with discontinuous spiral threads; subsequent whorls (protoconch II) bluntly angular, with fine opisthocyrt axial riblets ending in suprasutural spiral lira and microgranules, more densely spaced at riblets; transition to the teleoconch marked by a sinuated lip.

Occurrence. Box-corer samples BC05 (2 specimens), BC72 (2); core BC05 (1). Maximum height: 7.5 mm.
