Abstract: | A new genus and species of pedogenetic gall midge, Estoperpetua sakhalinica gen. et sp. nov., of the tribe Heteropezini (subfamily Lasiopterinae) is described. Gall midges have not been recorded in Eocene amber of Sakhalin. A female with 4-segmented tarsi, large transparent triangular sensoria on flagellomeres, short wings and legs, and long 2 + 9-segmented antennae is described. Heteropezidi shows the greatest generic and species diversity in the Late Eocene Rovno amber. Representatives of this supertribe were also found in the Late Eocene Baltic amber, Early Eocene Oise amber, Miocene amber from Mexico and Dominican Republic, and African copal. Heteropezidi from different amber faunas are reviewed. |
