Diagnoza

P₁ elements relatively elongated and M elements usually with relatively wide angle between processes.

Porównanie

A variable species, both in respect to the outline of platform in P₁ elements, which ranges from that typical to K. ultima to that of early species of Palmatolepis, but also in the prominence of the cusp and curvature of P₂ elements. The mean value of elongation index of the P₁ elements is, however, distinctly higher than in K. ultima (Dzik 2002, 2004), remaining elements of the apparatus being hardly distinguishable. In fact, to distinguish these chronospecies a large sample is needed and singler elements are of little taxonomic value. Some late populations (e.g., Pł-1; Fig. 80H-R) show robust denticulation of ramiform elements and widely angular processes of the M element
