Families

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]

Identification

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]

Phylogeny

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]
