Original diagnosis: Kirsch, 1991, p. 93
Chorate cyst with granulate, subsphaeroidal and in equatorial cross-section lenticular central body. From the central body arises a irregulary perforated membrane. This membrane is marginal and antapical characteristically dome-shaped and connected to the central body on single points. Archaeopyle apical (4A) with a zig-zag archaeopyle-suture. Operculum secate, foederate.

Original description: Kirsch, 1991, p. 93
This chorate cyst possesses of a relatively large, subsphaeroidal central body whith a granulate surface. Remarkable is the spronger development of the granulation (verrucae) on the marginal areas, while the granulation seems reduced on the central area. In the lateral area the central body is connected to the irregulary perforated membrane which covers dome-like flanks and antapex.
