Studied material. Several specimens in the studied samples (see Table 1).

Dimensions. Length of shell without distal projections 183 µm, maximum diameter 135 µm.

Remarks. Since there are two little different morphotypes of this species in the Valanginian of the S’Ozzastru section, also the specimens resembling those illustrated by Jud ( 1994) are included in this morphotype.

Occurrence. According to Jud ( 1994), the species is rather long-ranged, its FAD being recorded in her UA9 Zone, corresponding to the upper Berriasian and, according to O’Dogherty ( 1994), its LAD is as old as late Cenomanian.
