Diagnoza

High arched profile of P₁ elements, with dominant cusp.

Derivation of name: From similarity of P₁ elements to those of Branmehla inornata.

Porównanie

The apparatus reconstruction of this species has been proposed by myself (Dzik 1991) under the name Pinacognathus(?) sp. Its provisional taxonomic affiliation referred to the similarity of its P₁ elements to Carboniferous elements at that time classified in Pinacognathus, which later appeared to represent P₂ elements probably of Siphonodella (Dzik 1997). The M and S elements are closely similar to stratigraphically older V. unicus, being different only in bearing less numerous, usually not alternating denticles. But P₁ elements of these species are unlike each other, rather precluding any direct ancestor-descendant relationship.
