Diagnoza Suture with very weak umbonal lobe; large discoidal mature conch with globose juvenile stage. Porównanie The only specimen was found in the scree from a Famennian marl at the Kadzielnia quarry in Kielce. Specimen of Conditolepis falcata extracted from a piece of the specimen is the only basis for its precise dating. The most unusual aspect of the species is very wide whorl cross section at early ontogenetic stages, exceeding that of D. petterae but closely approaching that of the specimen attributed to D. cf. D. bredelarense from the same stratum. The species was identified also at Enkeberg. Autekologia Występowanie geograficzne Kadzielnia. Zasięg czasowy C. quadrantinodosa or younger Zone.
