T y p e: Holotype identified by David and Pouyet (1974) as specimen 1859.50.769 from Eisenstadt deposited in the Natural History Museum Vienna.

M a t e r i a l: Only 6 specimens were found in the studied sections.

D i a g n o s i s: Colony encrusting, Autozooecia rectangular, hexagonal with two rows of marginal areolar pores. Aperture semilunar with a straight proximal margin and oral spines. Avicularium large, suboral, always tapering distally, with a pivotal bar. Ovicells with a non-calcified horseshoeshaped distal margin, endoecium strongly porous.

R e m a r k s: Autozooecia grow very regularly and develop large avicularia and ovicells with a horseshoeshaped porous endoecium resulting in a very decorative budding pattern.
