Abstract

A new species, Megastigmus thyoides Kamijo (Hymenoptera: Torymidae), which emerged from seeds of Atlantic white cedar, Chamaecyparis thyoides (L.) B.S.P., collected in eastern United States is described and illustrated. This is the first record of this genus exploiting seeds of Cupressaceae in the Nearctic region. An average of 7% of the seeds collected from five sites in North Carolina were infested with this seed chalcid.
