First discovery of Plutarchia (Hymenoptera, Eurytomidae) in Palearctic region, with description of a new species from South Korea

The genus Plutarchia is discovered in the Palearctic region for the first time. In this study, we report a newly described and newly recorded species from South Korea: P. fuscipennata sp. nov., and P. malabarica Narendran & Padmasenan, 1990, respectively. The host association of Plutarchia malabarica reared from leaf -miner flies (Diptera: Agromyzidae) attacking the seeds of Pueraria lobata (Willd.) Ohwi (Fabaceae) has been unknown until now. A key to the South Korean species and descriptions of the new species are also provided.
