Scatopsoidea is a superfamily of true flies that comprises the families Canthyloscelidae, Scatopsidae, and Valeseguyidae.^[1][2] There are about 400 known species worldwide but more may yet to be discovered, especially in the tropics.^[2]

In Scatopsoidea, the posterior margin of the katepisternum is displaced to a more posterior disposition, causing the pleural suture to be folded. The superfamily also has a well-developed sperm pump and associated apodemes.^[1]

Based on morphological features, Scatopsidae and Canthyloscelidae are sister groups to each other, and Valeseguyidae is the sister group to them.^[1]

An analysis of nuclear and mitochondrial gene markers supported the monophyly of Scatopsoidea. It also found that this superfamily is the sister group to Bibionomorpha.^[3]
