The Pamphilioidea are a small superfamily within the Symphyta (the sawflies), containing some 250 living species restricted to the temperate regions of Eurasia and North America. These hymenopterans share the distinctive feature of a very large, almost prognathous head, which is widest ventrally. The superfamily consists of two extant families.[1]
