Diplommatina ristiae View in CoL n. sp.

( Figs 12 View FIGURES 10 – 14 , 30 View FIGURES 29 – 32 ; Table 1)

Diagnosis. Diplommatina ristiae n. sp. is characterized by its minute-sized, indistinctly ribbed shell, the lateral constriction of the last whorl and the ventrolaterally right position of the spiral palatal fold.

Shell ( Fig. 30 View FIGURES 29 – 32 ; Table 1). Dextral; spindle-shaped with conical early whorls and a narrowed last whorl; with 5.25–6 whorls separated by a deep suture; protoconch smooth; teleoconch with indistinct ribs (22–31 on the penultimate whorl; fewer on the last whorl) and a few very coarse ribs on the cervix; spiral striae between the ribs only locally visible; light corneous; subtranslucent; last whorl rounded, with a right lateral constriction; aperture subangular, angular at the transition from columellar to basal side; upper insertion of the peristome distinctly ascending towards aperture; insertions of the peristome connected by a partly detached callus; peristome distinctly expanded, thickened, doubled; aperture with a prominent columellar lamella, which remains high to ventrolaterally right inside the last whorl; with a long parietal lamella from lateral right to ventrolateral right inside the last whorl; with a spiral palatal fold ventrolaterally right inside the last whorl and with a short radial palatal fold laterally right; umbilicus closed. Shell height 1.63–2.0 mm, shell diameter 0.95–1.25 mm.

Remarks. Diplommatina ristiae n. sp. is most similar to D. perpusilla . For a comparison see there.
