Arthropoda Hexapoda Insecta Pterygota Odonata Anisoptera Libellulidae Orthetrum coerulescens

I think these specimen are Orthetrum coerulescens and not Orthetrum brunneum, even if the ♂ has some cells duplicated in a specific area of the wing (left wing three, right wing one) which should be a safe criterion according to Bellmann BELLMANN7.
