C. F. Fallén described 15 species of Lauxaniidae, the types of 13 could be studied in the collection of Fallén in the Swedish Museum of Natural History, Stockholm and one type is located in the collection of Zetterstedt in the Zoological Museum Lund. The type of Sapromyza multipunctata was not found. Lectotypes are fixed for 12 species. Homoneura subnotata Papp is a new junior synonym of Homoneura notata (Fallén). Homoneura notata auctt. nec Fallén is now called Homoneura dilecta (Rondani, 1868). Homoneura interstincta (Fallén) has been misidentified in the past. It is fully redescribed and illustrated. Homoneura mediospinosa sp. n. (= H. interstincta auctt. nec Fallén) is described and illustrated. Sapromyza pallida Fallén is unrecognizable, because the only existing syntype, belonging to the Lyciella illota group, cannot be properly identified.
