The Borsoniidae are a diverse group of conoid gastropods primarily united by molecular data (Bouchet et al. 2011).

Characters (from Bouchet et al. 2011): Shell small to large (5–80 mm), fusiform to biconic, sometimes with strong to obsolete columellar pleats. Sculpture usually well developed, axial ribs sometimes obsolete to absent. Siphonal canal short to moderately long. Anal sinus on subsutural ramp, deep. Protoconch when multispiral with up to five whorls, initially smooth and then with arcuate axial riblets, when paucispiral up to two smooth whorls. Operculum with terminal nucleus, fully developed to missing. Radula, if present, of hypodermic marginal teeth that usually have a weakly developed solid basal part, often attached to the ligament. Tooth canal opening (sub)terminally or, sometimes, laterally. At their tip teeth can have weak to rather strong barb(s). Overlapping of tooth edges is weak. Radula occasionally completely absent.
