Unknown Species

I hope these Chinese specimens are not determined completely wrong... :-/ Comments or suggestions to give a better name is much appreciated, thanks a lot! Many images are preliminary - I know - and I'll replace them by sharper one and add more information as well — Andreas Plank (2008-05-29)
