Thuringopteryx, a "Permian" mayfly in the Buntsandstein (Insecta, Pterygota)

Abstract

The Misthodotida have been known from the Permian only. However, Thuringopteryx gimmi KUHN, 1937 from the middle Buntsandstein of Thuringia, Germany, usually considered to be a representative of the Odonatoptera, Palaeodictyptera or Saltatoria-Ensifera, belongs in the stem group of the mayflies, sharing with the Misthodotida a one-branched CuA and with Misthodotes a short Sc. Hence, the Misthodotida survived at least until the early Mesozoic. The phylogenetic relationships of Misthodotes and its closest allies are outlined.
