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 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. Hundreds more await description.
Muhlenbergia is a genus of plants in the grass family.

Hemipenthes is a large genus of flies belonging to the family Bombyliidae (bee-flies). There are many described species, distributed throughout the Holarctic realm.

A number of species formerly in this genus were moved to a separate genus, ins in 2020.
