摘  要:Aphids are marked by their high polymorphism, but species reported from the Early Cretaceous are known only from alate morphs. The discovery of an apterous adult morph in Lebanese amber and a larva of the same species are very important for the understanding of both the morphological and biological evolution of this insect group at the very early stage of development. Gondvanoaphis estephani new subfamily, new genus and species of the recent aphids family Thelaxidae is described. The characters of the new genus in respect to other genera placed in Thelaxidae are reviewed. The palaeoeeological and palaeogeographical data concerning Gondvanoaphis new genus are also discussed.Aphids are marked by their high polymorphism, but species reported from the Early Cretaceous are known only from alate morphs.
