Diagnoza Slender P1 elements virtually without free blade and any lateral lobe of the platform; minute basal cone (pit). Porównanie The transition from the biramous latest Frasnian ancyrognathids to this species has been documented; probably the early Famennian type species of the genus derived at the transition. Schülke (1999) attempted restoration of the apparatus but only identification of P1 elements is supported here. Ramiform elements similar to those associated with Frasnian species of Ancyrognathus co-occur with platform elements of A. sinelamina in the Holy Cross Mountains. Autekologia Występowanie geograficzne Jabłonna, Wietrznia, Kadzielnia, and Miedzianka. The species occurs also in the Dębnik area. Zasięg czasowy Late K. triangularis and early K. crepida Zones.
