Abstract: Being implied in flight, mimetism, communication, and protection, the insect wings were crucial organs for the mega diversification of this clade. Despite several attempts, the problem of wing evolution remains unresolved because the basal parts of the veins essential for vein identification are hidden in the basivenal sclerites. The homologies between wing characters thus cannot be accurately verified, while they are of primary importance to solve long-standing problems, such as the monophyly of the Palaeopte… Show more

“…Three‐dimensional X‐ray tomography and reconstructions are very efficient in helping to determine the homologies of wing venation among insects, as has already been shown in recent studies (Desutter‐Grandcolas et al ., ; Jacquelin et al ., ). Here, it allowed us to demonstrate the existence of a PCu vein in most insect orders, and suggest that this structure most probably originated only once in insects.…”

“…The absence of the particular PCu structure could be explained, however, by the reduced 'anal'/posterior area of the wing. In the Odonata there is also no particular convex and curved bulla posterior of the cubital veins; however, we observed a vein forked into an anterior convex branch and a posterior concave branch that emerges from a bulla that is in a very basal position (Jacquelin et al ., ); posterior to this vein, there is only a membranule (a small membrane at the posterobasal angle of the wing) with very weak veinlets (in some fossil Isophlebioidea) or no vein at all. This forked vein corresponds to the anal vein followed by the 'jugal' area of the Polyneoptera.…”
