Diagnoza
Porównanie Conodonts of this species are the most common near the topmost bed of the Dzikowiec section of the Gattendorfia limestone. Elements P2 are minute, short-bladed, and sharply denticulated. Elements S seem to differ from associated Neopolygnathus purus elements in their shorter processes. The M elements have undenticulated and sometimes almost completely reduced ventral processes. The S3-4 elements are very similar to juveniles of Neopolygnathus, but seem to be separated from them, apart from short ventral processes, in a fan-like arrangement of denticles, usually with the base of the process projecting externally.
