Diagnoza
Relatively large, asymmetric basal cone (pit); rhomboidal outline of platform in P1 element reaching almost the ventral end of the blade in mature specimens. Porównanie
One specimen from Kowala shows a large basal cavity, transitional in size and shape between that in the preceding species and typical D. kayseri. Rare ramiform elements associated with P1 elements typical of the species are too generalized to prove its generic affiliation, but their morphology does not contradict affinities with advanced Dasbergina.
