 Diagnoza All mature elements with smooth, very flat cusps expanding on both sides into sharp thin cristae. Porównanie The most characteristic feature for the species is very flat M elements, unlike those of related species. Although the number of collected specimens is limited and their preservation not good, as a result of the unusual fragility of these thin cristate elements, it seems that the apparatus structure was closely similar to that of its probable ancestor D. arcuatus. Their S2-4 elements are hardly distinguishable. Autekologia Występowanie geograficzne Zasięg czasowy Rare specimens of the species occur from 1.3 m below (E. lindstroemi Subzone)up to 1.9 m above the bentonite (A. tvaerensis/superbus transition zone).
