thanks a lot for looking closely to my picture. Your remarks with regard to ID are very useful, they oblige us all to take our task on TN seriously. As a first response I add in the workshop area a picture with the undersides of the wings. I sincerely hope that you evaluate it and tell me about your conclusions. I will have no problem changing the ID if I see my error. Blues are difficult and "errare humanum est" (the useless stuff I learned at school...).
My best regards
