Der stammesgeschichtliche Aussagewert der Pterostigma-Oberflächenfeinstruktur bei Odonaten 1,2

The phylogenetic significance of ultrastructure of the pterostigma surface in Odonata

Studies of the pterostigma surface in dragonflies with the stereoscan microscope have shown that its ultrastructure presents a phylogenetic significance and indicates evolutionary affinities. The constitution of this ultrastructure is not suitable for the distinction of genera; according to the results obtained up to now, all genera of the same family have the same surface structure. In the present paper, we have studied particularly the complex super-family of Calopterygoidea, and a new phylogenetic arrangement of its different families is suggested.
