Shell very small, turbiniform, with a short spire, fragile, colourless and rather transparent. Proto-conch of heterotrophic type C, with a little more than one visible of about 290 µm in diameter. The teleoconch consists of about 1 Vz whorls, and bears a prominent spiral cord at its beginning, resulting in a slight elevation of the end of the protoconch. This cord is present on all of the shell, thereby separating it in two parts: the subsutural one which is a little depressed at the beginning and almost horizontal and the part below the cord, which is lightly convex and smooth. The growth lines are prosocline and irregular. At the base, a new spiral cord appears, forming an infundibulum for the umbilicus, which is deep and wide. Aperture ovoid, with a very fine peristome, which is a little angulous at the top and the bottom. Columella slightly curved without any tooth. Dimensions: The holotype is 0.85 mm in height x 0.76 mm in diameter.

The main distinguishing characteristics of the new species are the wide and well-defined umbilicus bordered by a spiral cord and the presence of another subsutural spiral cord.
Another Odostomia species with a wide umbilicus is Odostomia umbilicatissima Penas & Rolan, 1999, but this species lacks the spiral cord around the umbilicus and the subsutural cord; furthermore the shell is larger (1.5 mm), the suture is very deep and the protoconch is of type B.
