Mythicomyiidae
 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 humpbacked thoraces and lack the dense vestiture common in Bombyliidae. Mythicomyiids have until recently not had much attention in the literature.
