|Pseudacteon sp. (Phoridae)|

The Platypezoidea are a superfamily of true flies of the section Aschiza. Their closest living relatives are the Syrphoidea, which for example contain the hoverflies. Like these, the adults do not bust open their pupal case with a ptilinum when hatching, and thus the Aschiza do not have the inverted-U-shaped suture above the antennae. They are, however, muscomorphs, and thus have a particular type of pupal case resembling a rounded barrel and called "puparium".
5 families are placed in the Platypezoidea, listed below in taxonomic sequence:
- Phoridae - coffin and scuttle flies (includes Sciadoceridae)
- Opetiidae - flat-footed flies
- Ironomyiidae - Ironic flies
- Lonchopteridae - spear-winged flies, pointed-wing flies
- Platypezidae - flat-footed flies
Ironomyiidae, Lonchopteridae and Phoridae are sometimes separated as Phoroidea. The reduced Platypezoidea thus created unites the two families of flat-footed flies.
