Sutural ramp extending partially onto preceding whorl. Last whorl narrow, rather conic. Spiral sculpture of obsolete threads, present only on first teleoconch whorl. Second and last whorls lacking spiral sculpture, even on base. Axial sculpture of very short shoulder costae formed by small spinelets. First whorl: 9–10 costae. Second whorl: 8–9 costae. Third whorl: 11 costae. Aperture narrow, occupying 97% of total height, 15% of diameter. Inner lip straight, columella with five strong folds succeeded posteriorly by one weaker fold, one or two secondary folds intercalated between major folds in a few specimens; inner lip callus narrow. Anal sulcus thin, against suture. No shoulder sinus. Outer lip thin, not thickened externally. Siphonal canal short; siphonal notch shallow; siphonal fasciole low, weak.
