The previously monotypic genus Coryptilus Gibson (Hymenoptera: Eupelmidae) is revised and two new species are described based on females: Coryptilus circalatus Fusu sp. nov. from the Oriental region and Coryptilus longicervix Kawano & Fusu sp. nov. from both the Oriental and far eastern Palaearctic regions. Coryptilus is known only from females and previously only from the Oriental region. An illustrated key to the three known species is provided.
Eurytoma tomentosaesp. 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. tomentosa. A key to the two Eurytoma species feeding on Prunus in South Korea is provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
