T y p e: Holotype deposited in the Muséum National d´Histoire Naturelle in Paris under the number NF 61360 ( Poignant, 1991).

M a t e r i a l: Only one specimen has been found.

D i a g n o s i s: Onlyoneautozooeciumhasbeenfound, triangular from lateral view with a terminal, small aperture. Frontal wall porous, but due to the preservation, pores are not visible. Dorsal wall with a calcified stolon, open on both sides.

R e m a r k s: The preservation is poor, but the shape of the autozooecium and the position of the stolon on the dorsal side is very characteristic for this species. A detailed description is given by Zágoršek (2000). This is the first occurrence in the Miocene.
