Material.

Five specimens from Saal (collection Lang), two of which are illustrated herein: SNSB-BSPG 2021 XV 5, 6.

Description.

The largest specimen is 5.3 mm high. The shell is slender with a high and acute spire. The whorls are high and have a distinctly oblique ramp accentuating the sutures. The ramp is demarcated from whorl face by an angulation. The whorls are ornamented with broad axial ribs, that are fading on the last preserved whorls. The transition from whorl face to base is evenly rounded. The base is smooth. The damaged aperture is oval, acute adapically, and has a siphonal canal.

Relationships.

Ceritellopsis gramanni Huckriede, 1967 is much stouter, has lower whorls and a nearly horizontal ramp. Ceritellopsis huckriedei Gründel & Kaim, 2006 has lower whorls, a horizontal ramp and its axial ribs are bent backward adapically. Orthostoma longiscata Buvignier sensu Buvignier (1852) is distinctly slenderer. The species with the same name, Orthostoma longiscata, sensu Buvignier (1843) resembles C. plicatula more closely in shape but has a horizontal ramp and more axial ribs. Ceritella elata de Loriol var. striata Maire, 1927 has a spiral ornament and lower whorls.
