The genus Coccophagoides (Hymenoptera: Aphelinidae) is revised herein and two new species are described. These are Coccophagoides comperei Doutt and Coccophagoides utilis Doutt. Both C. utilis and another new species, Anthemus inconspicuus Doutt (Hymenoptera: Encyrtidae), are primary parasites of Parlatoria oleae (Colvée). They were collected in Pakistan and have been imported to California to control this olive pest.
