Diagnoza

Smooth, cylindrical crest concave axially. Two large, flattened lobe−shaped  radial processes well developed, either connected proximally to form a large oval foramen, or disconnected and defining a C−shaped slit.

Porównanie

This cyclocystoid is quite unlike any other species described. Slight morphological similarities do suggest, however, that it could be ancestral to Apparatocycloides satanus Boczarowski, 2001.
