Description

Shell trochoid, about 20 percent higher than broad, with about 2.5 rather convex whorls. The mouth is entire, without any sign of a siphonal notch or channel and is attached to the bodywhorl for only a minor part of the circomference. All teleoconch whorls are spirally striated and a somewhat more conspicuous spiral encircles the well-developed umbilicus. The last whorl occupies about 0.75 of the total height. The form of the clearly tilted protoconch, consisting of about half a smooth whorl, differentiates this species from many other Skeneidae.
HEIGHT: 0.5 - 0.6 mm, breadth: 0.45 - 0.55 mm. HOLOTYPE: Central Tyrrhenian Sea (RMNH Leiden, no. 55981) from detritus dredged at 200 m deep.

Interchangeable taxa

Anekes (now Lissotesta!) gittenbergeri differs from Cingulopsis fulgida (ADAMS, 1797), Cingulopsis pumila (MONTEROSATO, 1884) and related species not only by its spiral sculpture and its lack of any colour, but, more important, by its totally different protoconch. For the same reason A. gittenbergeri cannot be confused with juvenile Rissoidae of Skeneidae as found in European waters.

Lissotesta gittenbergeri can be recognised by the strong, very symmetrically arranged spiral cords all over the shell. The species was, together with L. turrita placed in Anekes by van AARTSEN & BOGI (1988), but species of that genus have a normally coiled protoconch, and a characteristic sculpture of sharp, raised lines.

Distribution

Western Mediterranean and the adjacent part of the Atlantic, 100-400 m.
