Diagnoza

Triramous P₂ element, rhomboidal outline of platform of P₁ almost without any lobe; straight or slightly asymmetric juvenile specimens.

Porównanie

P₂ elements with additional process occur rarely but consistently in samples with T. variabilis, being probably end-members of population variability expressed mostly in bending of the element. They start to dominate the sample in the Kadzielnia section between samples Ka-3 and Ka-5.
