Shell medium for the subgenus, fusiform. Aperture ovate. Columellar lip smooth, adherent posteriorly and slightly erect on 3/4 of its anterior part. Anal notch shallow and large. Outer apertural lip barely erect and crenulated; briefly striated interiorly. Spire high, consisting of 2 rounded nuclear whorls and 6 slightly shouldered postnuclear whorls. Suture appressed. The body whorl bearing 3 large varices of which the last one shows short spines, corresponding to the spiral cords and connected with a thin webbing, extending also on the siphonal canal. The two preceding varices are ornamented with shorter spines. Other axial sculpture consisting of a large intervarical node. Spiral sculpture consisting of 12 to 14 cords, flanked with 2 minor threads. Siphonal canal long, narrowly open and slightly recurved dorsally at the tip; ornamented with 2 or 3 short open spines, connected with a thin webbing. Color light brown with darker coloured intervarical nodes and medium part of the varices, aperture white. Dimensions: Holotype 33.2x18.5 mm; paratype 29.5x15 mm.

This species may be compared with 2 more or less closely related species: Chicoreus laqueatus (Sowerby, 1841) and Pterynotus (Pterynotus) martinetana (Roding, 1798). From the first it differs by its aperture, more rounded and more denticulate for P. laqueatus which shows also fewer spiral cords, a shorter siphonal canal and in which the varices are ornamented with longer webbed spines. From P. martinetana it differs by its number of varices, the spiral cords, the more denticulate aperture for P. martinetana, which also has a different columellar lip and protoconch.
