Interchangeable taxa

The unique type can probably be best com-pared with Turbonilla (Pyrgiscus) corsoensis Bartsch which has similar axial ribs and the same number of spiral lines. However, the present species possesses a more slender shell, with the later whorls less shouldered, and the arrangement of the spiral lines entirely different.
