Diagnoza Straight, almost transversely oriented inner process of M element with prominent denticles, relatively long external process of S3-4 elements extending almost along the same line as the cusp. Porównanie This is a rather generalized prioniodinid but the shape of the M element makes it different from all other Famennian prioniodinids occurring in the region. Also the delicate and mostly alternating denticulation of elements is rather unusual for the prioniodinids enabling rather easy separation of its elements from those of associated members of the family. The species has a rather short range of occurrence in the Holy Cross Mountains but probably was represented in the whole area, as it has been found at Jabłonna and Ostrówka, which are relatively distant from each other.
