Interpretive Summary: In the course of a “classical” biological control program against the glassy-winged sharpshooter a new species of an egg parasitoid with potentiality for the control of GWSS was reared in Tamaulipas, Mexico, from eggs of at least two close relatives of GWSS. The new egg parasitoid was compared with Nearctic egg parasitoid species and revealed that it represents an undescribed species, which is described in the current study. Molecular data further confirm its identity as a new species and its likely conspecificity with forms from Argentina and Peru.

Technical Abstract: A new species of Gonatocerus Nees (Mymaridae) is described from the states of San Luis Potosí and Tamaulipas in Mexico, with additional records from Argentina and Peru. Type specimens of G. uat S. Triapitsyn sp. n. were reared in Mexico from eggs of proconiine sharpshooters (Cicadellidae: Cicadellinae: Proconiini) in the genera Homalodisca Stål and Oncometopia Stål. Taxonomic and molecular evidence from five gene regions (28S-D2, ITS1, ITS2, COI, COII) is provided to help differentiate the new species from the morphologically similar taxon, G. ashmeadi Girault, which also belongs to the ater species group of Gonatocerus.
