摘要

We describe herein a new aphid genus and species Daoaphis magnalata gen. et sp. n., belonging to the extinct family Oviparosiphidae from the Middle Jurassic (ca. 165 Ma) Daohugou beds, Ningcheng County, Inner Mongolia, Northeast China. The new genus is considered to be the earliest certain representative of this family and the body remains of one of the oldest aphids. The evolutionary position of this new genus and distribution of the family are discussed.
