Tryphoninae
The Tryphoninae comprise a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Most species of the Tryphoninae are koinobionts ectoparasitoids of Symphyta larvae, but members of some genera ( e.g.'' Netelia'') are ectoparasitoids of Lepidoptera larvae. Tryphonines have a hair-margined clypeus and two longitudinal parallel ridges occur on the first tergite. The female sometimes has stalked eggs projecting from her ovipositor.
Most species are Holarctic. Fifty-one genera are described.
