The family Braconidae can be identified with following key characters: Fore wing cross vein 2m-cu almost always absent, but present in Apozyginae and rarely in Histeromerinae, Rhyssalinae and Helconinae. Hind wing cross-vein r-m almost always antefurcal, but interstitial in Trachypetinae. Hind wing vein C+SC+R fused along all its length except for Trachypetinae. Joint between terga of metasomal segments 2 and 3 inflexible with suture, if present, sclerotized except in Aphidinae.
