Tachydromia is a genus of hybotid flies. It is widespread around the world, with species found essentially everywhere except the polar regions and some remote islands. They are not very diverse in East and Southeast Asia,^[2] or in Africa^[3]

Description[]

Tachydromia are minute, slender flies of shining jet-black color, that are almost devoid of hairs and bristles.^[2]

The globular head bears large eyes with large facets. Three ocelli are present. The two-jointed antennae are short. The vertical, rigid proboscis is shorter than the head.^[2]

The thorax is longer than broad. The slender legs bear microscopic hairs, but no bristles. The front femora are somewhat thickened. The males of some species have small spines on the middle femora or tibiae beneath.^[2]

The wings are narrow, with the costa ending at the fourth vein and sometimes thickened beyond the insertion of the first vein. There is no trace of an anal cell present. Some species show one or two dark bands across the wings.^[2]
