What is "crabronidae"

The Crabronidae are a large paraphyletic group (nominally a family) of wasps, including nearly all of the species formerly comprising the now-defunct superfamily Sphecoidea. It collectively includes well over 200 genera, containing well over 9000 species. Crabronids were originally a part of Sphecidae, but the latter name is now restricted to a separate family based on what was once the subfamily Sphecinae. As this change is very recent, the subfamilies of Crabronidae likely will each eventually be treated as families in their own right, as they have been treated as such by many authorities in the past (as in the catalog linked below).
