Abstract The paper presents the descriptions of new aphid taxa from Late Jurassic/Early Cretaceous locality of Khotont (Mongolia). Two new genera Secusellinaphis gen. nov., Vetellinaphis gen. nov. and three new species of the family Ellinaphididae are described. The newly described species are: Secusellinaphis khotontensis sp. nov., Vetellinaphis cracens sp. nov. and Vetellinaphis longalata sp. nov. These are the oldest representatives of the family. Phylogenetic relationships within Ellinaphididae, the position of the family with respect to the Palaeoaphididae and evolutionary aspects of the new genera are discussed.
