Shell slender, rather thick, of melanioid shape, with a brownish yellow periostracum and mainly axial sculpture. No specimen has more than 3.5 whorls remaining; independently of size the top whorls are completely dissolved, except in very small specimens. The sculpture consists of strong axial, slightly curved ribs, reaching from suture to suture and about 12 in number on the body-whorl. The spiral sculpture consists of three rather narrow and sharp spiral cords, which produce small nodes where they cross the axial ribs. Partly concealed by the suture a fourth, stronger, spiral rib marks the end of the axial ribs. On the basal area of the body-whorl there are three ribs of about the same strength. The aperture is evenly rounded in its anterior part and does not have a trace of a siphonal canal or notch. Dimensions. Height of holotype 8.7 mm, diameter 4.2 mm. Radula : Long and slender, taenioglossate. The cutting edge of the central tooth has a main cusp and 1-3 denticles on each side. The anterolateral supporting ridges are well developed. The lateral tooth is high and robust with an apical main cusp, 3-4 much smaller denticles externally and 3-4 gradually smaller denticles on the inside. The marginal teeth are flat and broad, with a hay-rake like, truncated apical part with 15-20 denticles of same size on inner and outer marginal. Operculum : Distinctly smaller and shorter than the aperture, thin, colourless, consisting of a little more than three whorls.
Soft parts : The head-foot has a larger and flatter snout than in species of Provanna. The tentacles have no trace of eyes visible, except in half-grown specimens. The pallial cavity is deep, reaches three-quarters of a whorl back. The lateral ridges of the osphradium are higher and more prominent than in species of Provanna. The rectum ends further back in the pallial cavity than in Provanna, 1.6 mm behind pallial edge. The leaflets of the gill are more numerous, less voluminous and lower, than in Provanna. There is no pallial tentacle.
The faecal pellets consist of mucus, detritus, fine particulate matter, mineral particles and remains of planktonic crustaceans.
