Diagnoza Longitudinal ribs on the platform of P2 elements characterize this species. Outside Missouri, it has been known from Thuringia. In the Holy Cross Mountains only a few elements have been found and they hardly offer anything new regarding the apparatus composition. In sample Ko-6 two P1 elements of different ontogenetic age are associated. Both show an unusually low and sinusoidal blade and are lacking a free carina (blade), suggesting that this is the end-member of the lineage, well represented in the material of Chauff and Dombrowski (1977).
