Shell small (<2.0 mm), formed by 3,5 whorls, with a relatively high spire, strongly bicarinate and widely umbilicate.
The protoconch measures about 270 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 1,75 whorls and two carinae which angle the shell, one peripheral and the other basal. The ornamentation is composed of spiral cords, ribs and axial folds with rounded cells in the spaces between cords.
On the adapical part, the spiral cords develop in zigzag. Seven cords may be observed at the beginning of the teleoconch, which are subsequently transformed into nodules by the crossing of the axial ribs, and become 17 in the last quarter-whorl between the peripheral carina and the suture. The space between the peripheral and the basal carinae is fully covered by spiral cordlets, whose number increases when close to the aperture, and by axial ribs that develop into thick folds from halfway down and over the basal carina. There are 14-15 thick axial folds on the last whorl, which give the shell a starlike profile in apical view. The base is concave and completely covered by thick axial folds and spiral cordlets.
Umbilicus narrow and deep, progressively occluded by the thickening of the columella; in its interior there are spiral cordlets. Aperture quadrangular, prosocline; parietal area with a thick callous layer; columella arched, thickened at the base forming a cord that occludes the umbilicus; outer lip modified by the carinae which angle it inter¬nally and also prolong it laterally.
Dimensions: the holotype is 1.34 mm in diameter.

The species is characterized by its high spire; the small size of the protoconch; the regularity of the nodulose cords and the large axial folds; its quadrangular aperture and the columellar thickening forming a cord that occludes the umbilicus.
Anticlimax serrata spec. nov. is extremely similar but is more depressed, has a slightly larger protoconch, more axial peripheral ribs and the umbilical funnel is smaller.

Only known from the Philippines between 12 and 80 m.
