Figs. 16f, j

1973 Dictyomitra sp. C . – Moore, p. 830, pl. 14, fig. 3.

1997 Pseudoxitus laguncula Dumitrică in Dumitrică et al., p. 60, pl. 13, fig. 19; pl. 14, fig. 1.

Dimensions. Length of shell 208 µm, diameter of shell 136 µm.

Remarks. This specimen is rather similar to the topotypes from Oman and partly to X. gifuensis illustrated by Tumanda ( 1989). Although the specimen illustrated by Moore (1973) from probably Berriasian-Valanginian of Site 167 of the Leg 17 of the DSDP is poorly preserved, it seems to belong to this species.

Ranged and occurrence. Known from early Valanginian to early Barremian. In S’Ozzastru section a single specimen was found in sample OZ836.
