Synonyms and other taxonomic changes
probably polyphyletic(1); vaguely defined and rather artificial chalcidoid assemblage: for example, it does not have the enlarged metafemora of the Chalcididae (except Chalcedectini), it does not have the quadrate (rectangular) pronotum of the Eurytomidae (except Spalanginae), it does not have the exserted ovipositor of the Torymidae (except for 2 genera)...

*Epichrysomallinae and Sycoryctinae recently transferred to Pteromalidae. Cratominae & Panstenoninae sunk into Pteromalinae(3)
close to 600 spp. in >200 genera of 18 subfamilies in our area, ca. 3500 spp. in almost 600 genera worldwide placed in ~30 subfamilies(1) [38 taxa recognized as subfamilies by different workers are briefly discussed in(4)]
Parasites on a wide variety of hosts.
Some are hyperparasitoids.
The adults of some species feed on the body fluids of the host, after puncturing it with the ovipositor.
Life Cycle
Some used as biocontrols
