Diagnoza Wide robust platform extending almost to the whole length of P1 element, ornamented with robust tubercles and ridges. Porównanie Pseudopolygnathus controversus Sandberg and Ziegler, 1979 is probably conspecific with this species. Notably, the early population of D. ziegleri from the L. styriacus Zone , with a rather angular outline of the platform and its fine tuberculation, resembles D. brevipinnata. The late population from the P. jugosus Zone is similar in those respects rather to Pseudopolygnathus ostrovkensis. It seems thus that this is an outshoot of the Dasbergina lineage homeomorphic with Pseudopolygnathus (in fact, both are closely related). Autekologia Występowanie geograficzne Kowala and Ostrówka.
