Mythicomyiidae, commonly called mythicomyiids, are very tiny flies (0.5–5.0 mm) found throughout most parts of the world, especially desert and semi-desert regions, except the highest altitudes and latitudes. They are not as common in the tropics, but genera such as Cephalodromia and Platypygus are known from these regions. Many of these "microbombyliids" have a humpbacked thorax (as in the Acroceridae) and lack the dense vestiture common in the Bombyliidae. Mythicomyiids have until recently not had much attention in the literature. Their small size has caused them to be missed when collecting. Yellow pan trapping and fine-mesh netting in Malaise and aerial sweep nets has resulted in a number of undescribed species from many parts of the world. A high diversity of both genera and species exists for this family in Africa, especially northern and southern portions. About 350 species are known (most in the genus Mythicomyia Coquillett). Hundreds more await description.

Because of their extremely small size and curious body shapes, some genera have been at times placed in the

terga (placed in the pleural membrane in Bombyliidae). Augmenting the morphological characters, it is also a much older lineage than any known Bombyliidae, dating from as far back as the Middle Jurassic (Palaeoplatypygus Kovalev; Callovian: 163–168 mya) with other genera known from the Cretaceous (Procyrtosia Hennig and Proplatypygus
Zaitzev).
