Distribution

Sinetectula farinosa gen. et comb. nov. has a remarkably wide range, from eastern Africa (KF) to Japan ( Okutani 2000: 477, pl. 237 fig. 113, as Hindsia nivea ), Hawaii ( Pease 1860: 142) and the Marshall Islands (KF).

Remarks

Sinetectula farinosa gen. et comb. nov. is recognisable by its broad, ovate shell in combination with a rather cancellate sculpture.

The furrowed edge of the labral lip is typical of the genus, very similar in shape to S. egregia , with a similar tendency to arrange the cusps in pairs, but the slightly deeper basal notches accentuate the basal cusp much less (see Fig. 4B, F View Fig ).

The protoconch is multispiral, consisting of 2 to 2½ whorls, the last whorl with a tiny suprasutural spiral keel (see Fig. 4D View Fig ).

Sinetectula egregia gen. et comb. nov. differs from S. farinosa gen. et comb. nov. by its lower number of protoconch whorls (1 vs 2 to 2½), the slender shape with a higher spire, the weaker sculpture with finer spiral cords and finer axial ribs, the weaker denticles on the columella and the higher number (usually 12) but weaker knobs inside the outer lip.
