The shell is moderately small for the genus (length 37 mm) and broadly fusiform. The spire is high, consisting of seven or eight subangulate, postnuclear whorls and a protoconch of undetermined nature. The suture is impressed. The body whorl is moderately large and fusoid. The aperture is small and ovate, with a narrow, shallow, callused anal sulcus, this parietally delimited by a strong, transverse tubercle. The outer apertural lip is erect and marginally serrate, and its inner surface bears 11 strong denticles: four in the shoulder region and seven below, in the body region. The columellar lip is detached and erect, with three elongate, oblique pustules, increasing in size anteriorly. The siphonal canal is sealed, moderately broad and short, straight, and dorsally recurved at its tip.
The body whorl bears four webbed varices. Ad-ditional axial sculpture consists of two costae, a prominent one close to the older varix, a less prominent one at the trailing edge of the next varix. Spaces between the axial elements are deep. Spiral sculpture consists of two groups of major cords, one starting just below the shoulder margin, the other near the base of the body. There are also two minor cords on the shoulder, a single minor cord between the two groups of majors, and another minor cord below the lower group. Three major cords are evident on the canal, following a notable sculptural gap at the base of the body. Where the spiral cords intersect the varices, there are two groups of short spines, these corresponding to the cords. The major development of spines is seen only on the last varix, where the spines in each group, becoming slightly more separated toward their free ends, are connected to each other by a thin webbing. The three canal cords end in moderately long, unconnected, oblique spines. Shell color is pinkish-white, with suffusions of deeper rose-pink in various areas. The cords are deep golden orange. The aperture is white, with a rose-pink suffusion on the columella and on the densely fimbriate leading edge of the varix.

This extremely rare species has been reported, to our knowledge, only from Guam and Taiwan.
