Synonyms and other taxonomic changes
Formerly treated as a subfamily of Torymidae (Megastigminae).
Worldwide. Most of this family's diversity (9 of 12 genera) has been reported from the Australian region, but the diversity in other regions appears to be underestimated and many species remain to be described.
Many species are parasitoids of gall-inducing insects, while others are phytophagous (feeding on seeds or as gall inducers).
