T y p e: The holotype is deposited in the Natural History Museum Vienna within the Karrer collection from Baden. No inventory number provided ( Vávra, 1977) .

M a t e r i a l: Only 2 specimens from the borehole Vranovice VK-1 were identified.

D i a g n o s i s: Autozooecia oval, separated by shallow grooves. Apertures cleithridiate, large with a wide sinus and well developed condyles. Neither ovicells, nor avicularia known.

R e m a r k s: Hayward and Ryland (1999) stated that avicularia have to be present in this genus, but according to Gordon (pers. comm., 2004) even the type material does not always have avicularia. Because no ovicells have been observed in this species, the genus attribution remains uncertain .
