These are slender, medium-sized flies, with long abdomens. The femora are thickened, and bear two rows of spinules on the lower side. The costa is entire and the anal cell is elongated.


The biology of immature Megamerinidae is poorly known, but larvae have been recorded as predators living under bark or decaying vegetation.
