( Fig. 3 A–E)

Bellardiella lissochila Benthem-Jutting, 1963: 692 , Plate 28, Fig. 14.

Diagnosis. A small (H: 8.4–9.7 mm, D: 5–5.3 mm) Bellardiella (Szekeresia) species with an ovoid, nearly smooth shell (although all available shells are weathered), wide umbilicus, slightly suborbicular aperture, which is strongly oblique to the shell axis in lateral view, a strong parietal callus, a rather thin peristome, an umbilical tube, which is attached to the peristome, and a short angular tube.

Type locality. “ Island of Salawati , Waileh district ” .

Remarks. Operculum unknown. The thickening behind the peristome might be characteristic of the species, or might be due to teratological shell growth.
