Shell minute, rounded depressed, suture somewhat prominent, conical, with rounded whorls and impressed suture, empty shells cream-white in colour. Dimensions: holotype 4.8 mm in diameter; some shells are only of 3.0-4.0 mm. Protoconch with a little more than 2 whorls after the nucleus, apparently smooth. Diameter about 1 mm. Teleoconch with 2-2,5 whorls. Axial sculpture formed by narrow ribs more visible on the upper part of the whorls, but continuing mainly near the spiral sculpture of the periphery and the base. These ribs are strongly prosocline, straight, narrower than their interspaces. Its number is about 35 in the first whorl and about 50-52 on the second one. The spiral sculpture is formed by cords, only three at the beginning but the number increases quickly, and in the last whorls there can be as many as 12, which are strong, irregular, prominent, the peripheral ones more separate. In the crossing point with the axial ribs they form prominent nodules. On the base there is a wide umbilicus, limited by a prominent nodular cord where the axial ribs are less evident within the infundibulum and about 9-11 nodular cords appear inside the umbilicus. Aperture almost circular with a short part in contact with the previous whorl. The border of the aperture is simple and on it the end of the spiral threads and the infundibular border of the umbilicus may be seen. Soft parts: The animal, as examined from some retracted specimens preserved in alcohol, had a grey-green colour on the foot and head; long and tapered cephalic tentacles, eye stalks reduced without traces of eyes in its extremes, loss of cephalic lappets, very numerous tentaculiform processes around the margin of the buccal disk, the foot with two elongated anterior lateral expansions and some small micropapille and three epipodial tentacles. Operculum corneum, fine, multispiral, externally depressed at the middle and with numerous slightly visible radiating lines; internally smooth with an ovoid insertion trace. Periostracum dark orange, partly lost in most of the specimens. With the animal within, the shells present a grey-greenish colour. Radula typical of the genus, similar to that of the previously described species with the outer lateral teeth wider and less elongate.

Comparison must be made with species with more nodular shells:

* Solariella valida Dautzenberg & Fischer, 1906 is larger, with spiral cords more nodular, and a subquadrangular aperture.

* Solariella effosima and S. vaillanti are also larger, with a larger nodular first cord, fewer spiral cords on the last whorl and the umbilical infundibulum without spiral cords or with only a finer one.

* Solariella bojadorensis is more depressed, the more prominent cord is more separated from the suture, and there are two more prominent cords in the periphery.

* Solariella monodi Fischer-Piette & Nickles, 1946 has more prominent spiral cords, lacking axial ribs.

* Lirularia antoniae has a paucispiral protoconch, an evident shoulder, more depressed crossing of threads and ribs and smaller umbilical infundibulum.
