A New Species Of Eurytoma (Hymenoptera, Chalcidoidea, Eurytomidae) From South Korea, Feeding On Seeds Of Prunus Tomentosa Thunb. (Rosaceae)

Eurytoma tomentosae sp. nov., included in the Eurytoma amygdali species-group, is described from South Korea. This species could potentially be an economically important pest, as it interferes with reproduction by attacking the seeds of the garden plant P. tomentosae. A key to the two Eurytoma species feeding on Prunus in South Korea is provided.
