}}Diastatidae are a family of flies, and are in the order Diptera. They occur primarily in the Holarctic Region, but several species are known from the Oriental, Neotropical, and Australasian regions. Members of the family number over 20 described species in three genera. There is an additional fossil genus.[1] DescriptionFor terms see Morphology of Diptera Minute flies with grey or brown-grey body and, usually, maculate wings. The postvertical bristles on head are cruciate and vibrissae are present on the head are present.The front orbital bristles are inset and upswept. The costa is interrupted near the end of Radial vein 1 and sometimes also near the humeral crossvein. The subcosta is incomplete fusing with Radial vein 1 before the apex. The posterior basal wing cell and discoidal wing cell are separate. The anal cell of wing and the anal vein of wing are both present. BiologyAdults of living forms have been found along margins of bogs, marshes, and the edges of moist woodlands. Immature biologies are largely unknown. Hennig wrote about it thought to be Campichoeta punctum. Genera
