The Sphecidae, thread-waisted wasps, are a group of often large wasps whose gaster bears a more or less elongate petiole that is usually composed of the first gastral sternite only. Historically, the name has been used to cover all apoid wasps (i.e. Apoidea excluding bees), a group that now known to be paraphyletic.

Characters (from Bohart & Menke 1976, as Sphecinae): Inner orbits entire, converging or diverging below or parallel; ocelli normal. Antennae usually inserted near middle of face, sockets contiguous with to widely separated from frontoclypeal suture; male with 13 and female with 12 antennal articles. Clypeus transverse or higher than wide, rarely nasiform. Mandible without a notch or angle on externoventral margin; palpal formula usually 6-4 (rarely 6-3 to 6-1); mouthparts short to long; mandibular socket usually closed; occiput and hypostoma usually in contact or nearly so. Pronotum with a high, short collar or collar elongate, and somewhat depressed below level of scutum, rarely tuberculate; pronotal lobe broadly separated from tegula. Notauli present or absent but weak and short when present; no oblique scutal carina. Episternal sulcus usually present, usually extending to anteroventral region of pleuron; omaulus absent. Definitive metapleuron usually consisting of upper metapleural area only. Midtibia usually with two apical spurs; midcoxal cavities and coxae usually approximate, midcoxae without dorsolateral carina or crest; precoxal lobe present; hindfemur usually simple apically; claws with one to five teeth on inner margin, or simple; foretarsal rake present or absent; arolium usually large. Propodeum moderately long to very long; enclosure present, U-shaped, or absent; propodeal sternite present. Forewing usually with three submarginal cells and two recurrent veins whose end point is variable; marginal cell apex acuminate, rounded, or truncate. Jugal lobe large, occupying most of anal area, hindwing media usually diverging at or after cu-a; hindwing without subcoatal vein but with third anal vein. Gaster with cylindrical petiole composed of sternum I, displaced tergum I rarely forming part of petiole; tergum I without lateral carina or line; male with six or seven visible gastral segments; pygidial plate absent. Volsella of male genitalia usually with cuspis and movable digitus; aedeagal head usually with teeth on ventral margin; male sternum VIII variable; cerci present or absent.
