 Holotype marginal ossicle GIUS 4−793 Wie./524/2 from the Mid Frasnian, set D of Wietrznia II in Kielce; ventral and dorsal view 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.
