T y p e: Holotype deposited in the Natural History Museum Vienna under the number 1878.11.26, rediscovered by David and Pouyet (1974).
M a t e r i a l: Only one colony from the section Kralice nad Oslavou II has been found.
D i a g n o s i s: Colony encrusting, autozooecia rhomboidal with marginal areolar pores only. Orifice trifoliate, with very narrow marginal slits. Avicularia small, paired, suboral with a pivotal bar. Ovicells small, globular, partly immersed. The frontal wall with window of non-calcified ectoecium, where porous endoecium is visible.
R e m a r k s: The type specimen shows identical features with those of the studied colony. David and Pouyet (1974) listed this species under the generic name Hippoporina . Hippoporina has a porous frontal wall, a sub-circular orifice and a large ovicell ( Hayward and Ryland, 1999). Due to the presence of a trifoliate orifice and a porous window on the endoecium in the ovicell, this species belongs to Crepidacantha as described by Gordon (1984) and Bock (2010).
Reuss’ (1874) specimens show all the characteristic features visible on the studied colony. The only slight difference exists with respect to the width of the lateral slits of the trifoliate orifice. In Reuss’ colonies a few autozooecia have wider lateral slits than the autozooecia from Kralice nad Oslavou. This feature may perhaps vary also due to preservation.
