Description: Shell small (>2 mm), wider than high, formed by 3,5 whorls separated by a marked suture, with a low spire, widely umbilicate.
The protoconch has 1,75 whorls, measuring about 320 µm in diameter and having two distinct phases; the first is completely smooth and the second is covered by thick tubercles. There is no clear separation with the teleoconch except by the change of sculpture. The teleoconch has 2 whorls and 3 carinae, one peripheral, one basal and one peri-umbilical. The ornamentation is quite complex; it is composed of spiral cords, ribs and axial folds; rounded cells in the spaces between ribs and a filiform mesh occupying the cells.
On the adapical part, the spiral cords cross with axial striae in the first whorl to form 7 cords that develop in zigzag and show rounded cells between the cords; on the last whorl the ribs are more evident and intersect with the spiral cordlets to form small nodules; Up to 22-24 cords can be seen on the last half whorl.
The space between carinae (peripheral-basal) shows more than 30 fine spiral cordlets in apertural view; on the last whorl there are 20-22 thick axial folds on the the basal carina, which are projecting further than the periphery. Spire and base are convex, the space between the carinae is concave. Base is completely smooth on the last whorl; in previous whorls the axial ribs are predominant over spiral cords, with a groove-like space between the cords, limited by the axial ribs. A third carina, periumbilical, angles and limits the umbilicus.
Aperture quadrangular; parietal area covered by a thick callous coating, with an angle at the point of union of the outer lip with the previous whorl; columella arched and reflected towards the umbilicus; adapical part of outer lip crenulated externally by the the termination of the spiral cords; on it there are two angles that correspond to each of the carinae; the greater angle corresponds to the basal carina and expands laterally the aperture. Umbilicus height and width, which allows the previous whorls to be seen,limited by a carna that angles it; umbilical wall convex, smooth, with fine growth lines.
The early whorls of live specimens are brown from the digestive gland showing through the shell.
Dimensions: the holotype is 2.68 mm in diameter.

The species is characterized by the low spire; the spiral cords that are nodulose on the adapical part; the filiform ornamentation that runs through the cells and the completely smooth base.
The species with which it has more similarity is Anticlimax maranii spec, nov. which differs by the adapical nodulose cords; the greater number of spiral cordlets and smaller number of axial folds in the space between the peripheral and basal carinae, and in having the base completely smooth.
From A. dentata spec. nov. it is distinguished by its very low spire; the smaller size of its protoconch; the lack of ornamentation both on its base and umbilical wall and the less elevated aperture.

Only known from the Philippines, between 2-3 m, and Papua New Guinea, between 14 and 17 m.
Habitat: Infralittoral species collected in Philippines by suction on hard plateau with sand covering rocks, at 2-3 m (Stn. S32). In Papua New Guinea it has been dredged at 14 m (Stn. PS43) and 17 m (Stn. PB29).
