First report of the genus Dicladocerus Westwood (Hymenoptera: Eulophidae) from Korea with an updated key to the Eastern Palaearctic species

This study reports the genus Dicladocerus Westwood (Hymenoptera: Eulophidae) from Korea, with a newly reported species, Dicladocerus yoshimotoi Özdikmen. We provide a redescription of this species with photos of diagnostic characteristics based on paratype and Korean specimens. Due to subtle morphological variations among Dicladocerus species, we also provide a key to distinguish species within the Eastern Palaearctic region.
