Diagnoza

P₁ elements elongate and sinuous, with wide smooth platform bearing rounded triangular extension in the middle.

Porównanie

The species may be related to stratigraphically older C. lobicornis, from which it differs in the reduced lobe of the platform. At Wietrznia in sample Wtr-27 an early population of this species occurs with P₂ elements virtually lacking the platform, similar to those of C. falcata, that is without a recognizable cusp. Such an element was already attributed to the species by den Boogaard and Kuhry (1979). Younger samples with P₁ elements typical for the species contain P₂ elements with very wide, oval platform, closely similar to that in more advanced Conditolepis species. I suggest to distinguish early and late forms of the species on this basis. A robust appearance of P₁ elements characterizes populations with the platform of P₂ elements already well developed but not reaching the tip of the inner process (sample Md-27).
