Horismenus
Horismenus is a large genus of eulophid wasps (Hymenoptera: Eulophidae) comprising over 400 described species, primarily distributed in the Americas. Species are predominantly parasitoids, with documented associations including bruchid beetles (Coleoptera: Chrysomelidae: Bruchinae) in bean seeds, cerambycid beetles, mantid oothecae, and other insects. Several species exhibit hyperparasitoid behavior. The genus has been the subject of recent taxonomic revision due to cryptic species diversity revealed through molecular analysis.
