Orussoidea is a superfamily of sawflies. It contains the living family

Orussidae The Orussidae or the parasitic wood wasps represent a small family of sawflies (" Symphyta"). Currently, about 93 extant and four fossil species are known. They take a key position in phylogenetic analyses of Hymenoptera, because they form the s ...

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 ...

, the group containing wasps, bees and ants, with both groups together forming the clade Euhymenoptera. Like most members of Apocrita, but unlike other sawflies, members of the superfamily are parasitoids.

)-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)
