Wang, Y., Shih, C., Szwedo, J. & Ren, D. iFirst article. New fossil palaeontinids (Hemiptera, Cicadomorpha, Palaeontinidae) from the Middle Jurassic of Daohugou, China. Alcheringa, 1–12. ISSN 0311-5518.A new genus and species assigned to the extinct family Palaeontinidae, Synapocossus sciacchitanoae Wang, Shih & Ren, is described from the Middle Jurassic of Daohugou in Inner Mongolia, China. This new genus is established based on well-preserved fossil specimens with body and complete forewings and hind wings. It differs from other described genera by the following characters: small body size, RP and M1 coalescing for an interval on the forewings and M3 + 4 without bifurcation on the hind wings. The RP coalescence with M1 in Synapocossus Wang, Shih & Ren previously reported only in Turgaiella Becker-Migdisova & Wootton, seems to be associated with strengthening of the anterior wing margin. The intra-specific and individual variations of Synapocossus and numerous other insect fossils of northeastern China probably indicate long-lasting ecological stresses and a competitive environment in the Middle Jurassic to Early Cretaceous ecosystems.Synapocossus sciacchitanoae Wang, Shih&Ren;Palaeontinidae:, RPM1, M3+4, Synapocossus Wang, Shih&RenRPM1Turgaiella Becher-Migdisova&Wootton, Synapocossus
