Interpretive Summary: A widespread group of parasitic wasps that attack stinkbug pests was examined to aid in their identification. A previous grouping was found to be invalid, and a parasitic wasp that attacks bagrada bug, a major pest of cole crops (i.e., cabbage, broccoli, cauliflower, kale, etc.) was found to have been misidentified on previous occasions and was renamed. This species likely arrived in North America recently, and may prove to be an important biological control agent of bagrada bug.
Technical Abstract: A morphological and molecular analysis of Gryon Haliday (Platygastroidea, Scelionidae) was conducted to provide a taxonomic and phylogenetic context for a species under evaluation as a biological control agent of Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae). Our analysis revealed that Gryon is polyphyletic and that the biological control agent is not G. gonikopalense, a name that was tentatively applied to this species in 2019. We here describe this species as new, Gryon aetherium Talamas sp. n., and resurrect the generic name Hadronotus Förster. Morphological characters that delimit our concepts of Gryon and Hadronotus are presented. Based on morphological characters and the multilocus phylogenies, we determined that four presently valid scelionid genera belong within Gryon. In total, 14 species are transferred into Gryon from these genera, 217 species are transferred from Gryon to Hadronotus, and 6 species are transferred from Gryon to Dyscritobaeus Perkins. Reevaluation of specimens determined as G. myrmecophilum in Mexico and field studies in California reveal that G. aetherium is adventive in North America.
