The family comprises three genera per WoRMS, although the source describing
Archefulgur also divides it into three subfamilies (see synonyms below). The author who named them, Petuch, diagnoses them as "small-to-medium sized gastropods with inflated,
pyriform or
fusiform shells, most often ornamented with two rows of spines or knobs, one around the mid-body and one around the shoulder; some species have only a single row of spines around the shoulder; shell surface smooth and silky or sculptured with numerous very fine spiral threads;
siphonal canals elongated, narrow, separated from the
body whorl by a distinct constriction; siphonal canals often ornamented with strong spiral cords or a single large scaly ridge;
spire whorls generally elevated, protracted, or scalariform, most often ornamented with one or two rows of spines; parietal region glazed;
apertures wide and flaring;
protoconchs rounded, composed of two whorls." == Genera ==
