Type specimens Holotype: NMBE 553535 View Materials , Špilja Mandelaja, 10.9.2009, leg. Bedek ; Paratypes: 553299/2, Špilja Mandelaja, 10.9.2009, leg. Bedek; NMBE 553298 View Materials /2, Špilja Mandelaja, 10.9.2009, leg. Lukic;

Diagnosis Shell ca. 1.6 mm, conical, transparent, with both ribs and strong spiral striae, peristome roundish, with a straight parietal shield, columella with a parietalis and a weak columellaris.

Measurements (n = 5) sh: 1.49–1.65 mm (mean: 1.58 ± 0.064 mm); sw: 0.95–1.15 mm (mean: 1.052 ± 0.077 mm); ah: 0.8–0.94 mm (mean: 0.871 ± 0.057 mm); aw: 0.66– 0.71 mm (mean: 0.695 ± 0.018); number of whorls: 4.5–5 (mean: 4.75 ± 0.204).

Description Shell conical, translucent when fresh; the entire teleoconch costate, especially in the upper part of the whorl; ribs in the lower part of the whorl usually as strong as the spiral striae; strong spiral striae, in fresh specimens always more pronounced than, e.g., in Z. obesum ; aperture taller than wide; parietal shield well-differentiated from the lip, its margin straight; parietalis present in the aperture, though not very pronounced, extending one whorl into the shell, maintaining a constant size; columellaris either present in the aperture or starting just beyond, though not extending far into the shell.

Differing from all other species by its pronounced grid-like microsculpture, an entirely unique character.
