. A stem relative of dragon- and damselflies,Brunellopteron norradi Béthoux, Deregnaucourt and Norrad gen. et sp. nov., is documentedbased on a specimen found at Robertson Point (Grand Lake, New Brunswick,Canada; Sunbury Creek Formation; early Moscovian, Pennsylvanian) andpreserving the basal half of a hindwing. A comparative analysis of theevolution of wing venation in early odonates demonstrates that it belongs toa still poorly documented subset of species. Specifically, it displays aMP + CuA fusion, a CuA + CuP fusion, and a CuP + AA fusion, but it lacks the“extended” MP + Cu / CuA fusion and the “extended” (CuP / CuA + CuP) + AA fusion,the occurrence of which is typical of most Odonata, including Meganeura-like species. Theoccurrence of intercalary veins suggests that its closest relative might beGallotypus oudardi Nel, Garrouste and Roques, 2008, from the Moscovian of northern France.
