: Shell small (<3.2 mm), with a relatively high spire, strongly bicarinate and widely umbilicate.
The protoconch measures about 450 µm, has 1,75 whorls and 2 distinct phases; the first is completely smooth and the second is covered with thick tubercles scattered randomly. The teleoconch has 2 whorls and two carinae which angle the shell, one situated peripherally and the other basally. The ornamentation is composed of spiral cords, ribs and axial folds and rounded or quadrangular cells in the spaces between the cords, that have fine threads inside.
On the adapical part, the spiral cords develop in zigzag. At the beginning of the teleoconch 6 cords can be observed, which subsequently intersect with the axial ribs forming nodules; on the last quarter-whorl, between the peripheral carina and the suture there are up to 15-16 cords. The space between the peripheral and the basal carinae is fully covered by spiral cordlets and axial ribs which turn into thick folds extending from the middle area towards the basal carina. Up to 19 thick axial folds of similar shape and size may be seen on the last half whorl. The base is flat and completely covered by spiral cordlets and axial growth-lines.
The umbilicus is wide and deep, limited by a carina which angles it; in its interior there are spiral cordlets and marked growth lines; umbilical wall convex. Aperture quadrangular, prosocline, very high; parietal area with a thick callus; columella arched, thickened and reflected towards the umbilicus; outer lip modified by the basal carina which angles it internally and prolongs it laterally; adapical edge of the outer lip crenulated externally by the termination of the spiral cords.
Dimensions: the holotype is 2.35 mm in diameter.

The species is characterized by its high spire, the very wide protoconch and the ornamentation on phase 2 (of the protoconch); the regularity of the spiral cords on the adapical part; the regularity of shape and size of the axial folds in the space between carinae; the periumbilical carina, the high aperture and the presence of one single external angle on the external lip.

Only known from the Philippines, between 5 and 60 m, and Papua New Guinea, between 6 and 16 m.
Habitat: Infralittoral species collected by suction at 15-20 m, on hard substrate covered with sand (Stn. S22); on a reef slope with overhangs at 5 m (Stn. SI); on a muddy bottom at 21 m (Stn. S25) and on a muddy sand bottom, at 60-62 m (Stn. S32). In Papua New Guinea it has been collected between 2 and 16 m.
