Orussoidea is a superfamily of sawflies. It contains the living family Orussidae, as well as the extinct families Burmorussidae and Paroryssidae. They are the group of sawflies closest to the

Apocrita Apocrita is a suborder of insects in the order Hymenoptera. It includes wasps, bees, and ants, and consists of many families. It contains the most advanced hymenopterans and is distinguished from Symphyta by the narrow "waist" ( petiole) formed ...

parasitoid In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable str ...

)-Recent Burmorussidae is the earliest diverging group, with the Paroryssidae more closely related to modern Orussidae. The infraorder Orussomorpha was proposed for the grouping of Orussoidea with Karatavitidae, however Karatavitidae is now considered to be more basal than the clade consisting of Orussoidea and Apocrita (Euhymenoptera)
