Johnson (Hymenoptera, Scelionidae): new diagnostic data, distribution records and host associations.

Specimens of an egg parasitoid wasp, Johnson (Platygastroidea, Scelionidae), were reared from stink bug egg masses collected in the wild, in Maryland, United States. The egg masses were identified morphologically as (Stål), Stål and Dallas (Hemiptera, Pentatomidae). Molecular tools were used to further identify the egg masses as (Say) and (Say). All of these are new host associations for . We also provide data to contribute to future identification of : images of the holotype specimen and COI sequences from two disparate localities.
