Shell very small (<1.5 mm), wider than high, formed by 3,25 whorls separated by a slightly marked suture, with a low spire, widely umbilicate.
The protoconch has 2 whorls, measuring 340-370 µm in diameter and has three distinct phases, the first phase and the second phase, of about a half whorl, are completely smooth; then appears a third phase that is covered by small, regularly distributed, elongated tubercles. The teleoconch has 1,25 whorl and 2 carinae; the basal carina is the more prominent, while the peripheral, which develops in the last half whorl, may disappear in some specimens.
The ornamentation is composed of flattened spiral cords, axial ribs and rounded cells in the spaces between the cords. On the adapical part, the spiral cords develop in zigzag, 4-5 cords can be observed at the beginning of the teleoconch and 15-16 on the last quarter-whorl between the peripheral carina and the suture; no nodulose cordlets are apparent, while in the last quarter-whorl the axial ribs become more evident. The space between the carinae has 5-6 spiral cordlets in zigzag and rounded cells in their interspaces, seen in an apertural position; in general, the peripheral carina is scarcely developed: in some specimens it may be observed on the last quarter-whorl and in others it hardly shows at all. Profile with a convex spire and the space between the carinae straight or slightly concave. Base almost flat, with evident axial ribs that extend from the basal keel towards the umbilicus, penetrating inside. Aperture quadrangular, very wide; parietal area with a marked angle and a thin layer of callus that barely covers it; columella arched, thickened at the base and reflected towards the umbilicus, forming thick folds on it; the adapical part of outer lip not modified by the termination of spiral cords; the outer lip shows a single angle which corresponds to the basal carina and expands the aperture laterally. The height and width of the umbilicus allow the previous whorls to be seen and the umbilical wall is convex, with strong axial folds. Dimensions: the holotype is 1.29 mm in diameter. The largest shell measures 1.50 mm in diameter.

Anticlimax puncticulata spec. nov. is characterized by the ornamentation of the third phase of the protoconch, intermediate between A. infaceta and A. singularis; the presence of rounded cells in the spaces between the adapical cords and the periphery; the absence of nodules on the cords; the presence or absence in the last quarter of the whorl of a peripheral carina; the large apertural square with a unique angle in the inner part of the outer lip; the absence of marked axial folds between the peripheral and basal carinae; the axial costulation on its base and inside the umbilicus.
As in Anticlimax infaceta, A. singularis, A. bicornis, A. bicarinata and A. fijiensis, there are three different periods or phases in the protoconch development of Anticlimax puncticulata. This is not a common situation and we have no explanation for it. In the present species it is very evident in the protoconch scars and sculpture.
