Diagnoza High arched elements with flat sharp denticles, M elements with triangularly narrowed base, undenticulated, pointed external process and variable length and orientation of internal process Porównanie Because of the unusually wide range of variability it is not certain if truly only one prioniodinid species is represented in the late Famennian of Dzikowiec. However, there seems to be a complete gradation between extreme morphologies of the most characteristic M elements. Also the generic affiliation of the species is uncertain and it may as well belong to Idioprioniodus. In fact, some of its M elements resemble those of Ligonodina pectinata, others Idioprioniodus ruptus sp. n. The most characteristic aspect of most elements of L. sudetica is elongation of their cusps and sharp denticles and relatively short processes.
