Studied material. Three specimens in coll. MGP-PD, stub PD120 as follows: PD120 - OZ834- R09-17 , PD120 - OZ834- R10-19 , and PD120 - OZ839- R03-09 .
Description. Shell three-segmented, ovoid and smoothedfaced with sparse and irregularly distributed very small circular pores. Sutural pores very small and sieve structured (fig. 9j1). Aperture very small and simple. Intersegmental boundaries generally not marked by constrictions.
Dimensions. Height of test 92-101μm, of abdomen 67-77 μm, diameter of abdomen 71-81 μm.
Remarks. Despite its smooth surface, the assignation of this species to the genus Hemicryptocapsa (O’Dogherty et al., 2017) is erroneous, in our opinion, because this genus has a very small fourth segment and no sutural pore.
Range and occurrence. A long-ranged species, known from Middle Jurassic to Hauterivian.
