Porównanie

The most characteristic feature for the species is very flat ne element s, 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 ke and hi elements are hardly distinguishable.
