摘要：
Two new species, Ilerdocossus dissidens sp. nov., and Miracossus gongi sp. nov., and 10 new specimens assigned to known species of Palaeontinidae are described and discussed. All these specimens were collected from the Lower Cretaceous Yixian Formation of Inner Mongolia and western Liaoning. I. dissidens sp. nov., is different from other species of the genus in possessing a forewing with outer margin dentate; vein MP1+2 bifurcating distal of the level of indentation; MP3+4 bifurcating basal of the level of indentation; vein CuA(1) slightly curved anteriorly; branch CuA(2) curved posteriorly then recurved. M. gongi sp. nov., is different from the type species in having a smaller forewing with different colour pattern. (C) 2018 Elsevier Ltd. All rights reserved.
