The Nymphomyiidae are a family of tiny (2 mm.)slender, delicate flies (Diptera). Larvae are found among aquatic mosses in small, rapid streams in northern regions of the world. Many fossil species and a few extant species are known. Under an alternative classification, they are considered the only living representatives of a separate, archaic suborder called "Archidiptera". Nymphomyiidae are neotenic retaining various larval features. They have strap like wings with a very reduced venation and the wing margins have long fringes like those of Thysanoptera. The wings are shed after mating. The antennae are very reduced. Species in the genus ''Nymphomyia'' have atrophied mouthparts. These flies were discovered in a fast-flowing stream in Japan by Masaaki Tokunaga Entomological Laboratory, Saikyo University, Kuyoto. == References == *Courtney, G.W. 1994.
