Diagnoza

Flat elements with elongated sharp denticles.

Derivation of name: Referring to ancestral position to other species of the genus.

Porównanie

The new species differs from the type species (Rexroad and Varker 1992) in the delicate, relatively underived appearance of elements. Falcodus, as interpreted by myself (Dzik 1997) may be another descendant lineage related to this species.
