Thanks, Jostein! The most serious problem would be homology of "CuA". and, consequently, posterior veins. The single and strongly convex curved vein associated with posterior concave vein/pseudovein/fold is the main synapomorphy of Diptera. However, it is impossible to establish homology without digging deeply into fossils of all Holometabola
