It is represented by a well-preserved specimen with wings of 32–35 mm long and 13–14 mm wide and other peculiar diagnostic characters such an MP with four branches and a CuP with three branches. As all the other Dictyoneura species are known from the Namurian and/or the Wesphalian, Dictyoneura goujonorum n. sp. is the youngest representative of the genus. It is also the first record of the order Palaeodictyoptera from the Graissessac basin. The Carboniferous-Permian palaeodictyopterans are well-known to have lived in rather humid swamp forests. The global warming and drying of the climate during the Permian and/or the rise of potential predators may be responsible of their extinction. http://urn:lsid:zoobank.org http://urn:lsid:zoobank.org

However, these ichnofossils are much rarer than trackways, especially for winged insects. Here we describe a new full-body impression of a winged insect from the Middle Permian of Gonfaron (Var, France) whose preservation is exceptional. The elongate body with short prothorax and legs and long wings overlapping the body might suggests a plant mimicry as for some extant stick insects. These innovations are probably in relation with an increasing predation pressure by terrestrial vertebrates, whose trackways are abundant in the same layers. This discovery would possibly support the recent age estimates for the appearance of phasmatodean-like stick insects, nearly 30 million years older than the previous putative records. The new ...

Together with the previous discovery of a species of Blissidae in the same amber, it suggests that the Lygaeoidea were already rather diverse during the Paleocene, even if the Mesozoic record of this superfamily remains uncertain and scarce.
