The family Mythicomyiidae, commonly called mythicomyiids, are very tiny flies (0.5–5.0 mm) found throughout most parts of the world, especially desert and semidesert 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 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 tremendous amount of undescribed material from many parts of the world. A high amount of diversity of both genera and s
