M a t e r i a l: Altogether 4 specimens were studied, all from the section at Kralice nad Oslavou .

D i a g n o s i s: Colony encrusting. Autozooecia oval. Frontal wall with two rows of marginal pores, central area nonporous, slightly granular, with a small umbo. Apertures narrow, longer than wide. Number of oral spines varies from 5-7. Avicularia rare, large with rostrum tapering laterally. Ovicell prominent, globular, not immersed.

R e m a r k s: The species is up to now known only from the Pliocene of d´Altavilla ( Italy) but the characteristic features are identical with the specimens from Kralice nad Oslavou (small umbo on frontal wall, two rows of marginal pores and prominent globular ovicell).
