Species of medium size with a dark grey body, an aulacognathous jaw, with numerous grooves and smooth lateral extremities.
The shell is dextral, robust, slender with 7,25 to eight convex whorls and a marked suture. The body whorl is intermediate and the protoconch is smooth, with approximately 1,5 whorls.
The aperture is edentate, fuscous within, short and very wide curved and angular at the union of the columellar/palatal edges. The discontinuous white peristome is a little expanded and thickened into a lip, more developed in lower part of palatal edge and reflected and almost unthickened in the columellar edge, where it partially covers the umbilical slit. Older specimens have a nodule at the union of the parietal-palatal area.
The shell surface is shiny with a weak radial oblique striation. The first whorls are pale brown in colour, with a few, irregular whitish patches, whereas the last three to four whorls have a porcelain-like surface, which is a clear milky white with numerous irregular and radial oblique elongated dark brown patches.

A species endemic to La Gomera, where it occupies a small area of approximately 8 km2 at the North-east of the island, with typical lowland vegetation and subtropical scrub (vegetational zone 2), at an altitude of 200-550 m .
