The Ulidiinae are a subfamily of flies in the family Ulidiidae. Like the Otitinae, most species are herbivorous or saprophagous. Most species share with the Tephritidae an unusual elongated projection of the anal cell in the wing but can be differentiated by the smoothly curving subcostal vein. Most are dull gray to shiny brown or black flies with vein R1 setulose or, in a few cases, bare.[1]
