Ufens niger (Ashmead) (Hymenoptera: Trichogrammatidae) is reported for the first time as an egg parasitoid of the corn leafhopper, Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae), which is one of the most important pests of maize in the Americas. In addition, eggs of D. maidis were found to be parasitized also by Anagrus nigriventris Girault (Hymenoptera: Mymaridae) for the first time in Mexico. Ufens niger was found in 2016 in El Grullo and A. nigriventris was found in 2013 in Zapopan; both sites are in Jalisco State in central Mexico.
