摘要
The neuropterid (Neuroptera and Raphidioptera) fauna of the middle Eocene Coal Creek Member (Kishenehn Formation), U.S.A. is documented. Three families of Neuroptera (Ascalaphidae, Chrysopidae, Hemerobiidae) and two families of Raphidioptera (Raphidiidae, Inocelliidae) are recorded. Five new species and three new genera are described: Pseudoameropterus ambiguus gen. et sp. nov. (Ascalaphidae), Minimochrysa latialata gen. et sp. nov., Palaeochrysa greenwalti sp. nov., P. minor sp. nov. (Chrysopidae: Nothochrysinae), Macrostigmoraphia diluta gen. et sp. nov. (Raphidiidae). Two indeterminate species are also recorded: Megalomus-group gen. et sp. indet. (Hemerobiidae) and Neuroptera fam. gen. et sp. indet. The only previously described neuropterid from the deposit is the raphidiopteran Paraksenocellia australis Makarkin et al. 2019 (Inocelliidae). The neuropterid assemblage suggests a subtropical semiarid climate of the Coal Creek Member.
