New data on Cretaceous Palaeontinidae (Insecta: Hemiptera) from China

Yanocossus and Miracossus probably form a monophyletic group, which is the sister group of the “Ilerdocossus-complex”. Cretaceous palaeontinids except for Pachypsyche, Montsecocossus and Cicadomorpha probably form a monophyletic group. The extinction of Palaeontinidae in latest Early Cretaceous time probably resulted from the rise of primitive birds and mammals and the displacement of palaeontinid host-plants.
