Diagnoza

Heart-shaped outline of flat, smooth platform with margins gently raised aborally.

Porównanie

The apparatus composition was restored. It is here assumed that the type specimens of L. glaber and L. bilobatus represent modal morphologies of their populations, which are successive parts of the same lineage. The platform outline, originally used to distinguish these species is highly variable and identification of the species should not be based on single specimens. Probably equally useful is the changing morphology of P₂ elements, which became more arched in L. bilobatus.
