I've came into several problems while dealing with Platystomatidae. Firstly, is there a key for Palearctic species of this family? And secondly, Fauna Europaea gives Platystoma seminatione (Fabricius 1775) with six subspecies while most of other online catalogs give Platystoma seminationis (Fabricius, 1775) - which of those is correct?

Thank you for any suggestions ;)
