Genus Schizolepralia ZÁGORŠEK, 2001

Colony erect, multilaminar, with oval cross section. Autozooecia long, oblong with strongly porous frontal walls.

152 Aperture with a definite sinus. Neither oral spines, nor oral avicularia. An adventitious avicularium (sometimes with a pivot) is located in the middle of the frontal wall, near to one of the margins (left or right). Ovicell deeply immersed, small, with nonporous, convex, smooth frontal wall.

T y p e: Lectotype from Eisenstadt deposited in the Natural History Museum Vienna under the number 1867.40.291 (established by David and Pouyet, 1974).

M a t e r i a l: Altogether 19 specimens were studied in detail, more specimens were found at different localities however.

D i a g n o s i s: Autozooecia in 5-7 longitudinal rows with a strongly perforate frontal wall, separated by shallow grooves. Aperture with a long sinus, pronounced condyles and a short peristome. Primary orifice with a very narrow sinus. Avicularia drop-like, tapering laterally, sometimes with a pivotal bar. Ovicell unknown. Back side of the autozooecia strongly porous; chamber for adventitious avicularia can be observed.

R e m a r k s: Escharina has only marginal areolar pores ( Hayward and Ryland, 1999). The presence of adventitious avicularia on a perforated frontal wall and the sinus of the aperture clearly identify this species to be from the genus Schizolepralia .

The type has smaller avicularia, smaller pores and the shape of the autozooecia cannot be clearly recognized, when secondary calcification is more developed. It is however almost identical in shape of the aperture, position of avicularia and when less calcified also in the shape of the autozooecia.
