Diagnoza

Hooks with grooved pennon-bearing triangular teeth, elliptical in transverse section, perpendicular to the tooth slat. Along the slat there is a delicate lateral groove crossed by oblique trabeculae.

Porównanie

Differs from Pectenura hamata Boczarowski, 2001 by the shorter (on average) branches on lateral plates, the presence of a sculpted pennon and the lateral groove along the surface of the teeth slat. It differs from the other Devonian species by the structure of the base of the hooks; from Pectenura horni Haude 1982 by the development of accessory teeth.
