Description
The shell reaches a length of up to 3.7 mm and is fusiform in outline, with the width approximately half the shell length. Shell colour is uniformly pale beige, with a whitish band near the suture. The protoconch is paucispiral, consisting of about 1.5 smooth, glossy whorls and forming roughly 10% of the total shell length.The teleoconch comprises about four whorls and is sculptured with spiral cords and axial undulations, producing a weak reticulate pattern. The subsutural cord is slightly larger and more nodulose than the remaining sculpture. The aperture is elongated, accounting for about 60% of the shell length. The outer lip is internally lirate, bearing four to five weak spiral cords, while the inner lip shows a pair of low columellar folds. The siphonal canal is short and slightly projected forward.
