Abstract
Orianos brazai gen. et sp. nov. (Hymenoptera, Encyrtidae) is described and illustrated. Characters are given which should serve to separate the genus from related genera. The sole included species is an egg parasitoid of Agrilus sexsignatus (Coleoptera, Buprestidae), a serious pest of bagras, Eucalyptus deglupta Blume, in industrial plantations in the Philippines.
