Cyrtina arkonenesis

This is the (potentially) third species of Cyrtina that I've collected from Arkona. Cyrtina arkonensis is only known from the Arkona shale and that is where this specimen was collected.

I need to sit down and really investigate the differences between the three species I think I've found: C. arkonensis, C. coultisorum and C. hamiltonensis
