Abstract
A new genus and two new species of Kempyninae (Osmylidae), Ponomarenkius excellens gen. et sp. nov. and Arbusella magna sp. nov., are described from the Middle-Upper Jurassic of Daohugou (China). The finding demonstrates that extant kempynins, a typical Gondwanan group, are overshadowed by their Mesozoic relatives in taxonomic diversity and variety of wing venation. Striped patterns of both newly described species are an example of cryptic and disruptive coloration, possibly pinnate leaf mimesis. Eyespot patterns of Arbusella magna sp. nov. can be explained as a result of sexual selection. The abundance and distribution of the Mesozoic kempynins are discussed.http://zoobank.org/urn:lsid:zoobank.org:pub:CF33DEB4-0A69-407D-B1B2-1EC6537E4095
