Diagnoza

Subcircular outline of platform of P₁ elements with short and wide extension of the posterior lobe and blunt dorsal tip.

Elements of the species are generally much smaller than those of the ancestral K. wolskae, even at a stage of apparent maturity. The main distinguishing character is the rounded dorsal tip of the platform and strongly curved blade. No other apparatus elements have been identified with reasonable confidence.
